Float Se rvice:

Every month, recommend inspect ion every battery voltage.

Every three months, recommend equalization charge for one time.

Equalization charge method:

Discharge: 100% rate capacity discharge.

Charge: Max. c urrent 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

. cyc les, depth of discharge, ambient temperature and charging voltage.
