Lithium battery and trickle charging - April 11, 2014, 09:51 AM

So I purchased a Lithium battery at the end of the last summer since the last battery was crapping out from a motorcycle store in the NOVA area. The person who sold me the battery told me I didn't need to trickle charge the lithium battery which I sadly took his word for it and now I have another dead battery after a winter of being away.

I started to do some reading and I guess you are supposed to trickle charge them however you have to be careful when it comes to trickle charging them because you can overcharge them? Is this the case? How do other deal with lithium batteries and storage? What kind of trickle charger should I be looking at? I have some generic one from Walmart that im not sure

Thanks!

The lithium battery needs a specific charger so you do not 'over charge' it. I would highly recommend getting one to save your investment of that battery. If it not completely dead but not enough juice to turn the bike over you can turn on and off your ignition several times and it will 'wake up' the battery some and most likely fire the bike.

You can get the Shorai battery charge, but you don't need it.

Don't trickle charge lithium batteries. There is nothing wrong with charging them up with a standard battery charger (the bike does not put out anything special), but there is no need to leave them on a charger like a lead-acid battery for storage. They hold their charge in storage much longer than a lead-acid battery.

If anything, never charge it. When you are ready to go, hit it with a really fast charge just to get the bike started and let the bike handle the rest. YMMV.

I read that if your regular charger has a desulfate process as part of the programming, when it cycles through that it will ruin an Li battery.

I jumped the bike with my car and rode it some Friday night before the rain started. It started up fine yesterday too so ill see how this battery goes.

Def will put the money down for the trickle charger! Thanks!

Best thing for winter storage with a one of these batteries is to disconnect them from the bike. With no residual current draw from the bike electronics, it will stay charged over a winter with no problem. Just connect it up in the spring and fire it up and you should be fine. I do this with my track bike.

I have the Alien Motion and their balancing charger, but I have not needed the charger so far. Pretty much all of the manufacturers do not recommend using a standard charger on them, so I personally wouldn't do it. Too much invested in the battery to risk it for me. The right charger is cheap insurance and keeps you warranty alive.

Also depends what brand lithium battery to get too. My evo ballistic battery says you can use there smart charger or use a regular battery charger. It has something built in from preventing it from over charging. Normal battery chargers stops charging when it hits a certain voltage point, so the evo ballistic battery does the same thing.

Check your product manual to see what that company recommends.

Does anybody know if the 70s charging system technology is suffecient enough to charge lithium batteries? I bought a Full Spectrum for the project bike a while back but haven't used it since, and it's completely dead. It's the small old style P1 (I believe) so I'm not sure if plugging it into my Speed Triple will be safe. I was thinking about plugging it into the CB450 and ride it around for a bit to charge it up.

If it is completely dead then it is no good. What volt does it have in it? Any?
