What happens when an e-bike battery gets weaker?
An e-bike battery changes over time. This applies to all electric bikes, regardless of model. At first, you rarely think about it. The range is more than enough, and charging becomes something you do without reflecting on it.
You charge a little more often. You do not get quite as far. It is not something that happens from one day to the next, but something that builds up over time.
The battery loses capacity with use.
A battery wears every time it is used and charged.
This means that capacity gradually decreases, which in practice means a shorter range.
This is not a fault, but a natural part of how e-bikes work.
How quickly it becomes noticeable mainly depends on how often the bike is used. An electric bike that is used daily will also show the change more clearly.
Daily charging is part of normal use.
A common question is how often you can charge the battery.
We point out that the battery can be charged daily if the e-bike is used daily. In other words, this does not damage the battery in itself.
For many people, charging becomes a routine, just like charging a phone. The important thing is not to avoid charging, but that the bike works in everyday life.
When the battery is not in use.
One of the most important points in our guidelines is storage.
If the battery is not used for a longer period, it should be stored at around half charge.
Not full, and not completely empty.
It is a simple detail, but it affects how well the battery holds up over time. Even so, it is also one of the most common things people miss.
Common mistakes that affect the battery.
What stands out when you look at how e-bikes are used in real life is that many people make the same mistakes.
The bike is put away with a fully charged battery for longer periods
The battery is left completely discharged
You try to avoid charging despite daily use
None of this destroys the battery immediately. But over time, it contributes to the battery losing capacity faster than necessary.
How a weaker battery shows in everyday use.
When the battery starts to lose performance, it usually shows in small steps.
You charge more often than before.
The range becomes shorter.
You start planning your trips a little more.
The bike still works. The motor behaves as usual.
Only the time between charges changes.
E-bikes are being used more, and that affects the batteries.
E-bikes are used differently today than before. They often replace the car on shorter journeys.
The Swedish Transport Administration describes the e-bike as an efficient alternative for everyday travel in urban environments.
When the bike is used more often, the battery is also used more regularly. This makes the change in capacity more noticeable over time.
What matters in the long run.
It is easy to focus on range when buying an e-bike.
But what really matters is how the battery performs after long-term use.
Our guidelines are quite simple:
Charge when you use the bike.
Store the battery at around half charge when it is not in use.
Use the bike regularly.
