The battery of your Dyson e-bike uses a Lithium–ion construction and some care is needed to maintain the battery’s peak performance and provide a long service life.

How long will my battery last?

This is a common question and is a bit like asking, "How long is a piece of string" as there is not a simple answer.

The battery pack contains multiple, (40-50 depending on the model) 18650 cells. These cells have a stated life of around 500 cycles. A cycle is full to empty. If you use the battery until 50%, then recharge this counts as a half cycle.

If we are conservative and say the range on a full charge is 40kms, then after 500 cycles you would have travelled 20,000kms. For most riders this is between 5-10 years.

The cells very rarely fail, however they will decrease in capacity over time. Therefore, after say 5-years your battery will still function perfectly well, however the range will have reduced.

So the answer to the question on battery life is when the battery no long provides the range you require, in most cases this is equal to the life of the bike.

To help maintain the life of your battery follow these tips. 

1. Keep your cool.

Like us, an e-bike battery likes to be kept at a reasonable temperature, around 10-20 degrees Celsius is just right. Avoid parking your bike in direct sunlight, or leaving in a hot car.

2. Keep up the charge.

If you have ridden your Dyson e-bike and the charge is low, charge up the battery as soon as is practical before storing. If you haven't used your bike for 3-months, take the time to recharge the battery.

The battery is equipped with a Battery Management System, (BMS for short) which prevents over charging and stops the battery discharging beyond a voltage which could potentially cause damage to the cells. Once fully charged, remove the battery from the charger.

Unlikely old Nokia phone batteries, there is no need to fully discharge the battery before charging. You can recharge your bikes battery after each ride if you like.

3. Use the correct charger.

Never use a charger which wasn't designed for the battery.

4. Keep dry.

Avoid water and moisture from entering the battery. Use a damp micro-fibre cloth to clean your e-bike, never a hose.
