What are Battery Maintenance?

Maintenance of secondary batteries or lead acid batteries:

  1. Don’t leave battery discharge for long time or battery will become more difficult to charge due to lead sulphate deposit on plate.
  2. Avoid over discharging below 21 volts for 24 volts battery.
  3. Specific gravity of each cell to be maintained.
  4. Large variation between cells usually mean that one or more cell no longer retain a charge.
  5. Loose or corroded/ dirty terminates will cause the load current to drop.
  6. Don’t overcharge or over discharge.
  7. Don’t charge at very high or very low rate.
