equalize charge to reduce recharge time.
6.4 Charge
6.4.1 Float Charge Parameters:
Charge voltage: 2.23 ~2.30V/cell at 77°F (25°C)
The maximum charge current: 0.30C10
Temperature compensation coefficient: -3mV/cell (taking 77°F (25°C) as base point)
Total variation range of charge voltage is ±0.02V/cell
Note:
1) All cell/jar voltages of a battery string have a little difference at the beginning of use,
after approximately six months voltage ranges should tighten up.
2) Effects from too high float voltage or too low float voltage are: Too high for a long time
(overcharge): life shortened. Too low for a long time (not charged enough): Cannot meet
load and/or makes battery voltages inconsistent. The battery string capacity will drop
accordingly and life is shortened.
6.4.2 Cycle Usage Charge Parameters:
Charge voltage: 2.40 ~2.50V/cell at 77°F (25°C)
The maximum charge current: 0.30C10
Temperature compensation coefficient: -5mV/cell (taking 77°F (25°C) as base point)
Total variation range of charge voltage: ±0.02V/cell
Charge capacity is 110% ~ 130% of discharge capacity.

: -3mV/cell(25°C)
: ±0.02V/cell
Note:
Do not use equalization charging as the standard floating application. Adopt equalization charging
under recommended situations below:
1. Discharging capacity is below 80% of rated capacity.
2. Batteries have not been used for more than 3 months.
3. Float voltage of battery unit is less than 2.18V/cell
4. Batteries have been floating for 3 ~ 6 months and found low voltage batteries in the string.
5. Batteries have been floating for a year.
6. Batteries supplementary charged before used.
7. After performing a capacity test.
