Here is a chart showing the average life cycle of a properly maintained deep cycle lead-acid electric scooter and bicycle battery pack.


New deep cycle lead-acid batteries have a formatting period of 20-50 cycles and their capacity will increase during this time until they reach their peak capacity. While they are in the peak of their life cycle their capacity will remain relatively steady until they reach the decline of their life cycle.


During the formatting period you should go easy on the batteries by avoiding deep discharges and recharging the batteries more often than normal.


Battery packs should be fully recharged after every use and also recharged every 30 days when they are not in use.
