Maintenance & Cautions

Cycle Service

  • Avoid battery over discharge, especially battery sereis connection use.
  • Charged with recommend voltage, ensure battery can be full recharged.

In general, recharge capacity should be 1.1-1.15 times discharge capacity.

  • Effect of temperature on cycle charge voltage: -4mV/℃/Cell.
  • There are a number of factors that will affect the length of cyclic service.

The most significant are depth of discharge, ambient temperature, discharge rate, and the manner in which the battery is recharged.

Generally specking, the most important factors is depth of discharge
