How to Store Your E-Bike Battery

In plain English

Lithium batteries age fastest when stored full or completely empty, or in heat or freezing cold. Storing one partly charged in a cool, dry room slows that aging down. A battery left completely flat for months can switch itself off for good.

Work from the top. Steps go from free and easy to shop jobs. Switch the bike off before touching any connector. Tick each step as you go. Your progress is saved on this device.

1. 1Charge it to about halfFree For storage longer than a few weeks, many battery makers recommend a partial charge, roughly half full (for example 2 or 3 bars out of 5). Check your manual for its number.
2. 2Take it off the bikeFree Remove the battery so nothing slowly drains it.
3. 3Store it indoors, cool and dryFree Keep it at cool room temperature, away from heaters, direct sun and anything flammable. Avoid garages and sheds that freeze.
4. 4Top it up every month or twoFree Check the charge level every month or two, and top it back up to about half if it has dropped.
5. 5Wake it up gentlyFree Before riding again, let it reach room temperature, then fully charge it.
