Moreover, if other residents in your house own electric bikes, be sure to label the chargers to avoid mix-ups and battery damages.

Turn The Battery And Motor Off

Don’t’s Of Charging An E-bike

Now, what must e-bike users avoid when charging their electric bikes overnight and in general? Here are some of the most crucial errors that can damage e-bike batteries.

Storing Empty Batteries

It’s alright if you’re not using your e-bike every day. Maybe it’s too cold out there, or you’re busy with other chores. You might not be in the mood for bike rides.

Not Charging The Ebike Punctually

Some batteries, like the lithium-ion ones, are well-renowned for their extended life, but here’s a catch. They remain working even better when you charge them regularly.

30% is borderline, so it’s better to plug the e-bike as soon as you see the charging falling to 32% or 31%. It’s best to avoid using the e-bike even when it’s 20% to 25% charged to prevent further performance and lifespan problems.
