bmw airhead battery
For whatever test you DO, watch the voltmeter which is part of the tester, or, have your own digital meter connected to the battery posts ...the voltage must NOT sag quickly. 2016-feb-11 - Image result for bmw airhead battery relocation. You cannot expect full life out of a premium battery like the Odyssey if you store the battery where it is over 90°F for many months; no matter the advertising. Do check now and then that the timer still works and the charging is not too much, not too little (voltmeter)! $13.99 Battery Housing for Pre-1955 BMW Twins & Singles 6 Volt. Simply connect it to the bike battery and then put a common cheap timer on the power plug. You may not see bubbles if the charging current is quite low; and, it may not happen anyway for quite some time. Saved by ALEX BROWN. My suggestion is to charge relatively quickly to 14.7 volts, and then, if using a smart charger, float/maintain at ~13.6 volts. Allow a long time for the charging and rejuvenation. The mats do not have to be glass fiber but most are. I know of no Smart Charger manufacturer that will tell you these things! Setting the regulator without knowing that all is OK ...wiring, mounts, diode board, connections, grounding ...etc. This is Beemerboy’s new Stainless Steel Battery Box, suitable for all years of R65/R80/R100 Airhead BMW’s. INTRODUCING THE ORIGINAL BMW BATTERY PRICE FINDER. If the charging system is in good condition, and that includes all connections, even in the ignition switch!, and the voltage is too low, perhaps you should adjust the VR or get an adjustable one. The stator was redesigned with a center tap for the three windings (which fed to the diode board) and the rotor winding resistance was decreased to 3.4 ohms. ANTIGRAVITY BATTERY LITHIUM TRACKER. Keep in mind what average is, mathematically. If properly taken care of, both the Panasonic and the Odyssey, brands often talked about, are usually very good batteries; but, like ANY type of battery, one should pay attention to charging voltage/current & avoid excessive discharge for any period of time. HINT: When a battery is old or getting closer to failure (even not very old batteries can start dying), if your stock BMW dash voltmeter is wildly swinging during use of the directional (trafficators) flasher, & you have already checked the wiring and connections at various places, the battery may need replacing. At the end of the above period top off the battery cells again, to the same upper fluid level mark, using the same acid mixture. 2. You use it quite a few years beyond what Snowbum says you should ....it is now 8 or 9 years old (which you are proud of, and let everyone know on the Airlist and Facebook how great your selected battery brand is). Many early model Airheads, and many later models, both as stock items, came with the DIN type socket, mounted on a small bracket that is often located near the top of the left side rear shock absorber unit. The truck driver takes her to the bus station at her request. The testing should always be done with the Harbor Freight analog meter in the same horizontal or vertical position, to eliminate meter needle mechanical balance irregularities. There are positive & negative lead plates in the battery & they are not the same types of lead substances. NOTE that using 1/2 the CCA rating is a better test. 20. This will probably result in a longer battery life, and only quite slightly less life for your incandescent lamps, which will be a wee bit brighter while going down the road. Another item is that the AGM/VRLA type needs to have lots of plates, because the liquid electrolyte is being presented in a mat, thus, these batteries are tightly packed, leaving less ability for heat-related expansion and contraction. The stock size fuse was 8 amperes, but up to 16 amperes can be used if you use the socket for other purposes needing more current. There are several fixes I have used for this. Further, any charger must be capable of producing at least, during the initial charging ...a minimum ...of 14.2 volts, especially on the Odyssey. You report to a List or Forum that this is a lousy brand of battery. You are going to be very late for work this morning. Another brand with a decent reputation is MotoBatt. The pickup truck driver takes you to a motel, where you stay for two days while you await the motorcycle dealership opening; where you find they do not have the correct battery, but will have it for you the next day. 11. Most smart chargers will have no output, therefore no charging ...unless the battery they are connected to has at least some voltage (maybe 8v or greater??). A Smart Charger can be connected & plugged in all the time, according to many Smart Charger manufacturer's, but this is not the very best for the battery, contrary to common belief. For those that want to do it this way, it is simple. You purchase a battery. I have thought about the size needed for the Airheads, and I think one rated at 3 amperes or more would be fine for anyone, and one rated at 2 amperes would do for most, possibly even somewhat lower. I start from a cool engine & adjust the regulator after a 1 or 2 minute engine warm-up, which is enough warmup to allow me to go to 4000 rpm or so. What about Lithium batteries? Never connect or disconnect a battery charger unless its power plug is unplugged from the wall socket first ...that avoids sparks. 03/02/2006: Update on Digikey. There are now many choices; even more are going to be seen in the future. "Airhead… Rejuvenating. Your eyeball, with goggles on for safety! Be sure you are getting the actual brand, size and terminals, etc., that you want. Some literature will say there is an official sweet spot at 13.2-13.5 for flooded batteries. You do not get a motel room for two. A brand-new battery will start deteriorating immediately after being put into service, which is one reason batteries should be tested yearly, at least, by a load tester instrument. Suffixes are AP and P; both will work in an Airhead. 03/07/2019: Minor cleanup and minor clarifications. Put safety goggles on. Very knowledgeable BMW folks here. For bike batteries in the 14 to 32 AH range, you really need a charger rated at 3 amperes or more; and ones under 2 amperes are not good for longest possible life from a battery. If you have rubber mounts on the diode board, to change them to aftermarket solid metal ones before adjusting the regulator. You might also consider them for a Café bike. There is another peculiarity, not directly a Peukerts thing ...AGM/VRLA batteries can deliver somewhat higher voltage at the same time as having large loads. Do not use de-sulfating mode on lithium batteries! ....your battery may already have lost a lot of capacity, & may already have a decreased life, sometimes a large decrease. An AGM/VRLA such as the Odyssey or Panasonic might only need the charger every 2 to 3 months ...but do not fail to consider any clocks or other small drains ...they do add up! Construction methods can be wildly different. It protects the battery to a great extent at much higher temperatures than the none-metal case common versions; but, it also absorbs heat faster too. I highly recommend you do not use such a mode. There are certain models that can have timing chest to engine problems with painted touching surfaces, etc. There are smart chargers that have a de-sulfating mode. Made to suit Lithium Accu 12V / 290CCA Battery. https://bmwmotorcycletech.info/diodebds&grdgwires.htm. What it means on a practical simplified basis is that some batteries can be discharged (there is a re-charge effect too) at a higher % of capacity rate than others, with a minimal or less loss of total capacity. Nitpicking aside ...the CCA test is real world useful. Very long term charging can be done at 0.04 to 0.06 ampere. BMW released it as a sort of classic roadster … You must measure the voltage at the battery terminals themselves. The result is a cycle of gas>>>water>>>gas. Scenario #9: It either is already filled and deteriorating because Wal-Mart does not use chargers ...or, it is empty and YOU fill it with the acid that comes with it ...or you find at some other store. This avoids sparks. Connect your accurate digital voltmeter to the Harbor Freight units big alligator clamps. 10/02/2017: Some improvement in clarity, and a bit on color reduction. In many instances, these abused batteries, rejuvenated some, will draw a lot of charging current (which causes heat, and faster deterioration), and have other characteristics, that cause additional wear on your alternator charging system. There were two stators; the R90S had a stator with … The advertisements above are Google-sponsored. This will be denied by those trying to sell Smart Chargers. You failed to notice that the Wal-Martbattery has the + & - terminals reversed. 2016-feb-11 - Image result for bmw airhead battery relocation. If you have a K bike, you might find the fumes have caused intermittent problems with 'the computers'. They are available for $180 from Hansens BMW: (541) 535-3342, www.hansensmc.com .Hansens is constructing a web-page with detailed information, including … Ted Porter's Beemershop: Ted likes the Odyssey & also sealed Interstate batteries, such as models FAYIX30L & FAYTX20HL ...and get the plastic support plate. These figures are for batteries being stored with no loads attached (not even electro-mechanical clocks) and the motorcycle is not being driven during this storage time. … You will find flooded batteries under such constant Smart Charger use to dry-up, that is, need distilled water to be added, and often this is within perhaps 4 months, most require it long before a year is up. 2016-feb-11 - Image result for bmw airhead battery relocation. Le migliori offerte per BMW R100 R80/7 BATTERIA culla Vassoio Cinturino di Cespugli di montaggio BOXER AIRHEAD sono su eBay Confronta prezzi e caratteristiche di prodotti nuovi e usati Molti articoli con consegna gratis! A high VR temperature should show lower charging voltage ...up to a few tenths of a volt. If the battery has been in use for some time, and the discharge amount is not great, you can certainly use a lower output charger. The bike starts and runs fine for the next few weeks. 4 "cells" are used in a "12 volt system" in this type of battery. If the current is low, and you can't see gassing, use the voltage measurement, and allow extra time. Then, use a real battery load tester to analyze the battery's condition. Let us say you have a quite well-maintained and not all that old Odyssey battery. Consider very carefully how your battery will be used, and under what conditions, etc. There is likely a small difference in the maximum height, as measured at the case top (& terminals stick up a wee amount too). Congratulations! $159.50 Warm & Safe USB Power Coax Adapter. Guess what happens if you try to start your motorcycle with a jumpered-battery, perhaps from another bike or a car, and you have a lithium battery..? You might well disregard that, I find it rather wrong for initial charging, and the whole idea of a 'sweet spot' is never explained. However, all the batteries under discussion here are for those with some form of the element lead, and sulfuric acid as the electrolyte, whether in gelled or paste or liquid form; and, some have the electrolyte solution soaked into absorbent mats. Regarding load testing of the battery, voltage drop while cranking, etc. You will likely find that a Lithium-Iron-Phosphate battery of even half the true AH rating of the common Airhead-sizes of lead-acid batteries is very pricey! No matter what brand you get, be sure that the negative & positive terminals are on the correct side and correct left-right. R65 Bmw … 1. Some, on purpose, try to cleverly avoid information such as Cold Cranking Amperes (CCA) by using other terms that are of no importance, or even meaningless. It is important that gas bubbles be eliminated now & then during the initialization period & a full & complete soaking of the internal parts accomplished before any high current charging. This information applies pretty well to all lead-acid batteries. Further small updates were done as I obtained more information, particularly on LiFePO4 types, on 03/01/2015 & 03/17/2015. BMW sells the gray gel battery for this. This is especially critical during anytime the time the cell caps are off, so be sure the cell covers were replaced before using any charger. Scenario #7: There is a serious need for watching the charging process; ...particularly if using a Smart Charger that has a de-sulfation mode (charges to a rather high voltage for short periods or uses sharp voltage spikes). $50.00 + $9.99 shipping . When the voltage reaches the fully charged amount, turn the charger off. Float voltage is not the bike system voltage under alternator charging ...it is a floating voltage for charging during storage, or after overnight SmartCharger use, with the SmartCharger still connected and powered. Check the battery using a Load Tester and note the voltage change during the testing. Generally, the car versions are in stiff cases, the motorcycle types not so much, so they have a somewhat more tendency to swell upon overcharging and high temperatures. The pulse mode is better, but not worth a premium. storage time ...although the deterioration will not usually be excessive. I particularly like the two-meter larger one, I think it is much more versatile ....and more accurate ....and you can use it on your car or truck battery, not just a motorcycle battery. 9.8 volts or higher at 70°F ...AND....and thanks also, for your donations! Regular price $99.00 Sale price $99.00 Sale. ), it is impossible to give hard & fast rules here. You can use a digital voltmeter at the battery, & the motorcycle's starter motor, to perform a load test, with a very approximate resulting guess of the battery condition. 19AH tray, 185x83mm footprinnt. Possible strange battery discharging situation. See item #1, below. Boxer Magic: A BMW airhead cafe racer from Lithuania Like many things from the early 90s, the BMW R100R suffers from an identity crisis. It is because of the lowering of reliability that I have made my somewhat conservative recommendations for scheduled battery replacement & considerably based on load testing the battery regularly, using the load testing method I describe. The big thing with lithium batteries with respect to being heavily discharged, is that re-charging SHOULD BE started at a very exceptionally low rate! It runs well and has had a LOT of work done recently. Some of the sellers do not mention that if the battery is well-discharged, a sudden fast charging will destroy the battery; or, at least reduce greatly its otherwise expected life. Charging System upgrades, Ignition System upgrades and more. It seems the airhead battery needs to be robust enough to do the job. Another way of looking at all this ...is that the rated AH is more usable in high loading conditions on those batteries ...such as repetitive cold weather use of the starter motor on hard-to-start bikes, over and over, within a minute or three, perhaps. I recommend between 14 & 14.9 volts, this varies with battery construction, materials, and temperature. Your new battery will not have 100% of its plate areas initialized chemically nor electrically. 14.6 volts is lower than allowable for other types of batteries, which generally have a limit of ~14.9. Original BMW Batteries are designed and tested to deliver a longer service … If you are the type of person who does take care of your battery, you can possibly get as much as 50% longer life than my averages, but you probably will only get 20% additional life. DURING the cranking, also watch the voltage. 1. This website uses cookies. The AGM and GEL batteries and, in particular the lithium batteries, are less affected than the flooded types. Thus, a decent load test is done at about 90 amperes on a 30 AH battery. Set the Harbor Freight unit either standing up or the back is flat downwards, whichever position you intend to use, & so indicate it on the Tester, so you will always use it. Get In Touch FlatRacer, 7 Baker Road, Harlesden, London, United Kingdom, NW10 8TY Some literature, for some types of batteries, will show that the testing current should be 1/2 of CCA. ... Airheads Beemer Club Devoted to BMW airhead bikes and owners; Proper Initialization, which may here be somewhat more complex than the battery maker says, will lengthen battery life, with a small amount of extra effort. Vehicle batteries are no longer only the simple flooded (slosh) batteries of my youth. Many specialized chargers designed for these lithium batteries have special recovery modes, if the battery gets seriously drained. The LiFePO4 type is much more thermally stable & it does not have the thermal-runaway problems of the Lithium Cobalt types which can lead to a fire! Recharging the battery can usually recover almost all the original capacity & proper function of the battery. This "extremely long term trickle charging" is, as noted, done at 0.04 to 0.06 ampere. 25. Once that voltage is reached they automatically drop the charging voltage to one or even two lower levels, the final level is usually called the float level or maintenance level of charging ...which is just enough to maintain the charged condition; and that might be around 12.7 volts, some use higher. The batterybox is mounted underneath the gearbox at existing receiving points. When a dry battery has acid mixture first put into it, the battery will automatically gain a certain 'charge'. This is a real peculiarity, but it is true. Connect the Harbor Freight unit to the battery via its big alligator clamps. It needs to be installed into the starter relay plug. 13. $4.00 shipping. She turns you down for another ride, using a rather lame excuse. These are the models that are often rebuilt into Café Racers. Flooded batteries, additional information: A "flooded" battery usually has removable cell covers, contains liquid you can (or should!) Your own usage, and that includes a long list of things, makes, on average, a lot of difference in battery life. For either 1 or 2, above: I leave you to change to Fahrenheit, and calculate your conditions-effects. 09/16/2016: Update metacodes, scripts, layout, content improvements for clarity. You have had many years of use with no problems. Westco AGM Sealed Battery, 12V/30AH For K75/100 2 Valve Bikes Up To 9/92 & /6 & /7 Airheads Plus All R100R Models $129.95; Westco 12V30 AGM Battery/Battery Charger Kit $199.95; Accumate Automatic 12V/6V Battery Charger $58.95; Accumate Automatic 12V/6V Battery Charger/BMW Plug Adaptor Kit $69.95; Accumate BMW Plug Adaptor Cable $14.50 This can be partially true. The risk of expensive damage is particularly so on CAN-BUS bikes. $140. You could even use an old small light bulb for the resistor. The BMW R100RT was the touring version of the airhead series. It is raining. $150.00. Use a common low output non-smart type once every month or two, for just enough time to recharge the battery, but do monitor the voltage! A VRLA battery can have other chemistries such as cadmium, iron, etc. The stock charging system in the Airheads will work OK with a lithium battery (if it is not heavily discharged), but a small increase in charging voltage is appropriate ...just as it is for even the stock flooded battery, or any AGM/VRLA, because BMW set its stock voltage regulators fairly low, often found to be approximately 13.8 volts as measured at the battery itself. The better Smart Chargers (lots of brands) are very nice, and most can be left turned on for extremely long periods (years in some situations). A load testing done while watching the RATE of voltage lowering adds a LOT of information, and, while unknown, I will explain that, etc. One day you were tired and hungry when you got home from a ride, and you forgot to turn off the large screen GPS navigator on the motorcycle. That shortens them a bit. Some are a bit more honest and say they are 'equivalent-to'. Fits right below the tank above the stock airbox. The reason is due to possibly grounding the battery without the battery ground wire at the speedometer bolt being connected, after you have purposely disconnected it. 05/22/2013: Update the lithium battery information, condense it. Be sure that your grounds, cables, brushes, wiring inside the timing chest, etc. Then disconnect that charger and connect the Smart Charger. ✭, ✭ Copyright Vonzeti 2019 ✭ All rights reserved ✭. Thus, strictly speaking, fully sealed car batteries, which always have a gas pressure valve, are also VRLA types. You could do it faster by starting off with no more than 1 ampere, never exceed that amount, & keep raising the voltage as the charging current tapers off from the battery obtaining a charge. Best to use the Smart Charger every month or even three, for overnight. Congratulations! Let's say that battery has an ampere-hour rating of 28 AH. see (wear eye protection) if a cell cover is removed. This is because motorcycle batteries are located in a poor environment for best longevity, such as heat/cold/vibration & poor re-charging. Huge charging currents will cause spot heating in the battery, and such things as plate buckling, steam, etc., are likely....& quite possibly the battery will be destroyed. If you make a number of stop & go's, particularly short, say in busy traffic cities or traffic-backed-up freeway jams; maybe have more lighting & heated clothing; if the battery is not being recharged enough, ......the battery may not have enough charge to start your bike again. 10/29/2013: Update for clarity, add more cautions & information on DEsulfation mode problems. Eventually the battery is ruined. The storage or available capacity of that lithium battery (6 AH being assumed here), assuming no other large drains than just to start the engine, and means that you could crank, for a bit of time, each, quite a number of times ...allowing the starter to cool off between starting attempts (the way you really should use a starter). The higher the charging current rate, the more bubbles. The 3-piece fiberglass tray can be made either black (left) or gray (right). Similarly, they are not the type of battery you want if you expect to reliably start your bike in freezing conditions, as power output of these batteries falls off very fast when they are cold; and, bike batteries of the lithium type have very low true ampere-hours (AH) ratings. I advise you to consider the actual height of the battery you will be purchasing ...and your tool tray fitment. We have been selling batteries for BMW R100/7 (76 - 84) - 1000 cc online since 2003 and will have the correct battery for your Motorcycle in stock, available for next day delivery. You're likely to get loads of opinions on this. Becouse … It really is best to get a proper sized Smart Charger for commuters usage. Some manufacturer's do not furnish important specifications when promoting & selling their products. So, my present second-best is to fill to highest level line or even a bit more, with distilled water (if a flooded type that can have water added); then connect a cheap non-smart wal-wort low current charger to it, with a series resistor to limit the current flow to 0.060 ampere, as measured after a full charge ...and keep it in relatively cool place.
