Charging Time

The time required to complete each charge depends on the discharged condition of battery,

characteristics of charger used, or the temperature during charge. For cycling use, using

constant voltage charging, this time can be estimated by the following expression:

(1)  Discharge current: larger than 0.25CA  Tch = + 3 ～ 5

(2)  Discharge current: less than 0.25CA    Tch = + 6 ～ 10

Tch: time required for charge (hours)

Cdis: ampere-hour discharge before charge started

       I: initial charging current.

Complete charge time for float service will be slightly more than 24 hours.
