How to Charge Your E-Bike Battery Safely

In plain English

Lithium e-bike batteries are safe when they're treated well, but damaged batteries and wrong chargers cause fires. A few charging habits make a big difference, and they also make the battery last longer.

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. 1Use the right chargerFree Use the charger that came with the battery, or an exact replacement with the same voltage and plug. Never use a charger for a different voltage.
2. 2Charge in a safe spotFree Charge on a hard, non-flammable surface, away from beds, sofas and exits, where a smoke alarm can hear it. Don't cover the battery or charger.
3. 3Let it reach room temperatureFree After a ride, let the battery cool. In winter, let a cold battery warm up indoors first. Don't charge below freezing.
4. 4Stay nearby and unplug when fullFree Charge while you're home and awake, and unplug when it's full rather than leaving it on the charger for days.
5. 5Check it before chargingFree Look for swelling, cracks or damage, especially after a fall. If you see any, don't charge it. See a shop.
6. 6Have the battery testedShop job A shop can test the battery and its protection circuit and tell you if it needs replacing. Never open the battery pack yourself.
