What to Absolutely Avoid
-
❌ Leaving the battery on the bike in an unheated garage/shed. This combines the worst of all worlds: cold temperatures and potential parasitic drain.
-
❌ Storing it fully charged (100%) or completely dead (0%). This is the fastest way to ruin your battery.
-
❌ Charging the battery when it's freezing cold. If you bring the battery in from a cold car or garage, let it warm up to room temperature for several hours before plugging it in to charge. Charging a cold battery causes irreversible damage to the cells.
