General
All of our electric bikes have the latest generation batteries with battery management circuitry built into them. It has no memory, it can be charged at any level you wish. It is a better practice to top off your battery at your convenience rather than waiting until your battery is low to ensure maximum battery life.
The best way to look after the battery on your electric bike is to use it regularly. Leaving it discharged is likely to shorten its life. So ride your bike regularly and recharge it regularly. It's usually lack of use and lack of charging that causes problems.
Charging
Never leave your bike battery discharged for long periods of time. If you are not going to use your bike for a while, charge its battery every month anyway. If necessary get a monthly timer so it can be recharged every 4 weeks automatically. That way you can just plug it in and the timer will take care of it for you without you having to worry about it.
When your bike is new, fully recharge the battery at least one time, this conditions the battery cells. After that, there is no need to discharge the battery before recharging. There is no memory effect on batteries so you can top them up at any time, and we recommend that you do this.
You cannot overcharge the battery. The intelligent charger that comes with your bike reads the battery as it charges it and will switch itself off when the battery is full. So just plug it in and leave it overnight and it will ready for you in the morning.
Weather
In the winter or when it is cold, any battery will become less efficient. This is true of all batteries, you will be aware that after a freezing night and on cold mornings cars can be more difficult to start because the battery has got so cold. It is not quite the same with an electric bicycle, but if the battery is allowed to get very cold by being left out in a garage or shed, the battery efficiency will drop considerably.
This will result in the bike feeling a bit slower and the range or distance it will travel before a recharge is required will be reduced.
If you can bring your bike indoors when the weather is very cold it will not just help the battery, all the moving parts will run better as well, as the oils will be more efficient therefore reducing any drag and general wear on the bike.
Attention
Your electric bike relies on its batteries and you rely on your electric bike, so look after the battery and it will look after you. It is not unusual for a well-maintained battery to last for many years. Even though your bike will feel less powerful as the battery gets older and the range will diminish, you can continue using the battery for years to come.
Electric bikes do need a bit more attention than ordinary bikes, but these simple precautions will prolong their life, and give you many happy years of electric bike cycling.
