Battery Storage Over Winter

[LaszloB]

I have a 48 volt, 14 amp hour battery for my M2S Bike. I'll probably stop riding within the next month or so I won't ride until March or April. What is the best way to store the battery? Fully charged, leave it on the charger? Not on the charger?

Thanks

Store out of direct sun, 60 - 70°F, 60% charge, not on a charger. Check the charge level every 2 to 4 weeks and add some charge if it drops below 50%.

Thanks, my garage stays around 50 during the winter so that should work

It MIGHT be a good idea to keep it just a little warmer than that. While 50F is okay, optimal range for batteries is typically 15C to about 40C. 15C is about 60F IIRC, so you might see a little degradation. 50F isn't too bad though.

If you prefer keeping it in the garage as opposed to somewhere warmer, maybe check its charge more frequently (1-2 weeks).

Here is a handy chart for the optimal baterry temperature range.

Thanks, I can keep it in the house, I'll just store it in a battery bag

So you don't ride at 50F?

Not really, I'm good to about 50f on a sunny day Lol. What can I say, I'm a fair weather rider, like wearing shorts and not a lot over my torso
