Electric bikes are becoming more and more popular in 2022, and if you’re reading this you probably know that they don’t come cheap, that goes for the batteries too. So if you’ve already forked out lots of money on a brand new e-bike, you probably don’t want to be spending a big amount on a new battery if yours can’t quite cut it any more. So, we’ve compiled a list of tips to keep your electric bike battery in prime condition.


What is an e-bike battery?

An e-bike battery is a battery used to give specially designed electric bikes a bit of an extra kick. They are usually Li-ion (lithium-ion) batteries and are made up of multiple smaller batteries known as cells and a BMS (battery management system).

How do I make my battery last longer?

There are quite a few ways to help your electric bike battery have the longest life possible, here are a few of the best tips:


Ensure the battery is attached

This first tip may seem obvious, but you definitely don’t want your battery coming loose or coming completely off when you’re flying around the trails, make sure the battery is properly connected and attached to the bike.


Don’t fully drain your battery

If you can avoid draining all of the life out of your battery, it will definitely help prolong its lifespan. If the battery is fully drained, ensure it isn’t left empty by charging it up as soon as possible. It’s also worth making sure the battery is charged to around 85% or more, this will also help the battery stay healthy.


Correctly store your battery

If your battery isn’t in use for a long period of time, through the winter for example, you can’t really just leave it until you need it again. It is recommended to keep electric bike batteries in a dry, room temperature location, so probably not just in a shed outside. It is also vital to keep topping up the batteries charge every now and then to ensure that the battery doesn’t run flat. The battery will still drain over longer periods of time even when not in use, so check and charge the battery 1-2 times per month when the bike isn't being used.


Remove the battery when cleaning

It’s obvious that e-bike batteries can withstand some dirt and water, otherwise they’d be pretty useless, however blasting it with a hosepipe after every ride probably won’t do it much good. So if it needs to be cleaned, you’re probably better off just wiping off any dirt with a cloth, then putting it back on your bike after the bike has been cleaned.
