Brand new e-bikes don’t need any diagnostic, but sooner or later, the battery becomes less efficient than before. It may happen for several reasons:
- When charge-discharge cycles come to an end.
- When the battery reaches the end of its useful life.
- After a long winter in the garage in a discharged state.
- After overcharging or overdischarging.
- After exceeding the allowable cell currents.
- Due to inherently poor cell quality.
Loss of battery capacity on electric bicycles inevitably leads to a decrease in mileage on a single charge. Many people want to know how to test e-bike battery capacity. Battery management is highly recommended, and we’ll give you some advice you should always keep in mind because they are based on our own experience and big research.
So if the moment has come when your bike loses its power, it is time to use a multimeter. It’s a simple device that was created one century ago by a British electrician, who got tired of carrying three items in his bag and made one of his own. It's a pretty compact device, and it’s always good to have one, there are many models on Amazon, and they all work in the same way. We're going to give you a step-by-step tutorial, it’s really a great way to check out the charge of your bike. Keep in mind that your battery should be fully charged before the operation.
- Simply connect the device to an e-bike
- Check the continuity
- measuring voltage
- Test the resistance
It’s the most common way how to check e bike battery.
There are no special skills and techniques, but reading manuals is recommended. Overall it isn’t dicey at all, and you can make this procedure of your own even without deep knowledge. Don’t forget about full charge at first, usually, it takes around six hours for an average charging cycle.
