Discharging batteries is a function of your application.

Here are a list of helpful items:

  • Shallow Depth of Discharges (DOD) will result in a longer battery life. <50% DOD is recommended
  • 75-80% DOD is the maximum safe discharge for flooded and AGM batteries
  • Do not discharge flooded batteries >80%. This will damage (or kill) the battery. Recommend operating DOD for flooded batteries is 50% to 75% of capacity
  • A periodic equalization charge for flooded batteries is a must
  • Do not leave batteries deeply discharged for any length of time
  • Lead acid batteries do not develop a memory and need not be fully discharged before recharging
  • Batteries should be charged after each period of use
  • Batteries that charge up but cannot support a load are most likely bad and should be tested
