How to take care and repair the ebike’s battery?


Using electric bike is environment friendly. That is why more and more people are opting for it nowadays. On an average a single charge can allow you to ride about 30 kms. But with time, the capacity of battery goes on decreasing but you can enhance its life by taking good care of it. Charging it properly, cleaning and lubricating parts of the bike, not running the bike on full power every time and more precautions can really help the bikes battery to last longer.

With the advancement in technology, the batteries are made more powerful and long lasting but then too they can be damaged if not handled with care. 

Steps to be followed for repair

The repair of lithium batteries is easy and can be done at home. You need certain tools for doing that. You must have an old ebike battery, pliers, wire cutter, electric tape and a Multimeter to do so. You need to follow these steps to have the electric bike battery repair:

  • Open the old ebike battery first. Make sure that the inside battery remains undamaged as it will be used later.
  • Next, you need to cut the parallel connection between the cells but keep the series connection as it is. Then, with the Multimeter take the readings and measure the voltage of cells. The cell which has reading above or equal to 10.8 V means that it is usable. 
  • Now, connect active cells in series and measure the voltage. If the reading is around 36 to 42 volts then it is ready to use.
  • Now, open the damaged battery and throw away destroyed cells. Then, connect the old battery cells with the cells in the damaged battery. Most batteries have 6 cells inside it. The longest wire is negative and the rest three are positive so connect them accordingly. 
  • In the end recheck the connection and voltage. You can push the power button on the bike to see whether it is working or not. If it is not working, give battery a charge of 5 to 10 minutes and then recheck. In most of the cases it works. After that, you just need to reinstall the battery box and carry on riding your ebike.
