Battery Charging: 

To obtain the optimum cycle life performance from the Haze EV range it is vital that the correct charging profile is utilised. Haze specifies a charging profile with an equilizing/desulphation phase as detailed in the Haze document “Charging - Cyclic Applications” for flat pasted plates. 

Cycle Life:

To ensure maximum cycle life it is recommended that the battery be fully recharged as soon as possible after use. Cycle life is very dependant on the depth of discharge (DOD).

The following is a guide to the number of cycles expected.

100% DOD - 270 cycles

75% DOD - 350 cycles

50% DOD - 550 cycles
