Maintenance & Cautions

Float Service

  • Every month, recommend inspection every battery voltage.
  • Every three months, recommend equalization charge for one time.

Equalization charge method:

Discharge: 100% rate capacity discharge.

Charge: Max. Current 0.3CA, constant voltage 2.4-2.45V/Cell charge 24h.

  • Effect of temperature on float charge voltage: -3mV/Cell.
  • Length of service life will be directly affected by the number of discharge

Cycles, depth of discharge, ambient temperature and charging voltage.
