How to Test E-Bike Battery with Multimeter?

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. 

  1. Simply connect the device to an e-bike 
  2. Check the continuity
  3. measuring voltage
  4. Test the resistance

How To Check Electric Bike Battery With No Tools?

Battery testers are cheap and amazing, but if you haven’t got any, there is a solution, and we're going to show it. How to test an e-bike battery without a multimeter is pretty simple. There is a basic  equation:

distance*100\battery original capacity


Do it on an empty flat road and use full throttle until the battery is completely discharged to make this procedure properly. Afterward, you will have an approximate understanding of how much full capacity varies from original. A lithium battery is an excellent device, but it isn’t immortal, so don't feel bad if it needs to be repaired or replaced over time.
