E-bike battery care through the seasons

Lithium packs age fastest at the extremes of their charge range. For everyday commuting, top up to around 80 percent and recharge before the pack drops below 20 percent. Charge fully only before a long ride.

Aim for 10 to 20 degrees Celsius at roughly 60 percent charge for storage longer than a month. Avoid unheated sheds in winter: charging a pack below freezing causes permanent capacity loss.

Wipe the pack contacts with a dry cloth before mounting, and never pressure-wash near the battery mount or controller. A smear of dielectric grease on the pins helps in wet climates.
