- set it to DC Mode
- use the negative proper on the negative battery side (usually the black one)
- use the Positive Prope on the positive battery side (usually the red one)
- See reading on Multimeter
- if the reading same as the battery voltage means that the battery is capable to produce the correct voltage.
Note: if you have a softback battery you could test the charging ports as well using the same testing method.
Other Ways To Check Ebike Battery
There are some other methods you can use to check your electric bike battery.
The first option is to check the battery screen reading, which often gives you information about the number of charges you have charged, as well as the voltage readings and the remaining charging levels, and this information is useful in many situations because as it gives you quick information about the status of the battery.
The second option is to check the temperature of the battery during charging, as it is normal for the battery temperature to increase slightly during charging, but if the temperature is so high that you feel hot when you touch it this means that there is something abnormal.
In this case, it is preferable to start first Change the charger and then check the battery voltage and also the charging port in the battery.
The third option is to use a spare battery to compare the performance between the current ebike battery and the spare bike battery (this option may be useful if you have a battery that has the same capacity in which case you will be able to compare Apple to Apple) If you have a spare battery of a different capacity this option will not be practical.
Conclusion:
As a general rule, you can check your ebike battery using the below methods
- Using a Multimeter to check the battery voltage
- Doing a road test to check the range of the ebike battery compare it with the original battery range.
- Checking ebike battery information screen.
- Check the temperature of the ebike battery.
- Compare an ebike battery with a spare battery that has the same capacity.
