Battery Operation

Discharging batteries is entirely a function of your particular application. However, below is list of helpful items:

  • Shallow discharges will result in a longer battery life.
  • 50% (or less) discharges are recommended.
  • 80% discharge is the maximum safe discharge.
  • Do not fully discharge flooded batteries (80% or more). This will damage (or kill) the battery.
  • Do not leave batteries deeply discharged for any length of time.
  • 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. Refer to the Testing section for proper procedure.
  • Poor periodic maintenance can also contribute to battery discharge. Conditions such as poor battery cable contact due to improper torque can create high resistance connections that will increase amperage and reduce run times. Dirty and corroded terminals will lead to improper connections. Over or under watering will cause metallic component damage and electrolyte dilution or will sulfate the portion of the battery plate that is exposed to air.
  • Additional accessories will also accelerate battery discharge. Use of GPS systems, radios, heaters and coolers will shorten life and run time.
