Steps
Store the battery at around 50 to 60 percent charge, not empty and not full. A completely flat pack left for weeks can lose capacity for good.
For everyday rides, stop charging at about 80 percent. Charge to 100 percent only the night before a long ride, then ride soon after.
After a ride, let a warm battery cool to room temperature before you plug it in. Charging a hot pack speeds up wear.
Unplug the charger as soon as the light shows the charge is finished. Do not leave the bike plugged in overnight or for days.
Avoid draining the battery to zero on every ride. Recharge when it drops to around 20 to 30 percent.
Never charge a frozen battery. Bring it indoors and let it reach room temperature first, which can take a few hours.
Keep the battery out of extreme heat. Store it indoors at room temperature, away from radiators, sunny windows and hot garages, and never leave it full in the heat.
Use only the charger made for your bike. A mismatched voltage or plug can overheat the cells and start a lithium fire.
Clean the bike with a damp cloth instead of a pressure washer. Forced water can get past the seals and into the battery casing.
Tips and common mistakes
Charge on a hard, non-flammable surface such as concrete or tile, and do not leave a charging battery unattended.
Winter range loss is normal and usually returns in spring. A battery that stays weak in warm weather is genuinely worn out.
Check the charge level every two to three months during storage and top it back up to about half.
A battery that is swollen, smells strange or gets hot while idle should be replaced, not charged.
Questions
Should I leave an e-bike battery on the bike over winter?
It is better to take it off and keep it indoors at room temperature, charged to about half. Cold alone is less harmful than storing it full in a hot or freezing place.
How often should I charge a battery in storage?
Check it every two to three months and bring it back to around 50 to 60 percent. Lithium packs slowly lose charge and can be damaged if they sit empty.
Can I use a different charger if the plug fits?
No. A matching plug does not mean matching voltage or current. Use the charger supplied with your bike, or one the manufacturer lists for that model.
