How to Store Your E-Bike Battery
Winter and long-break storage
Quick answer
Store it partly charged (many manuals suggest roughly half), indoors at cool room temperature, and top it up every month or two so it never runs flat.

Free, and each takes under 5 minutes.
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.
Step-by-step checklist
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.
