5.1. Charging
CAUTION

The batteries must be charged under the specified conditions, using the charger
specified by GS Yuasa or the one included in the equipment. Using without recharging
may result in an insufficient load. If the batteries are charged under the conditions
other than those designated by GS Yuasa, it may cause the following negative effects
including leakage, heat generation and fire hazard.
a) Over Charge: Accelerated water loss and corrosion on positive grid.
b) Insufficient Charge: Deterioration of positive and negative active material.

Keep the surface temperature of the batteries below 50
℃
as much as possible while
charging. If the surface temperature rises above 50
℃
, it may cause the batteries to
break or deteriorate. Please stop performing a refresh charge to prevent the rise of the
battery temperature when there is a risk that the temperature rises above 50
℃ .
5.1.1. Standard Charging

Correct battery charging is very important for optimum battery life. Improper battery charging may
result in decreased battery life, battery leakage, potential risk of fire or other catastrophic battery
damage. Recommended charging is below.
Bulk
: 0.2CA (SLR1000:200A, SLR500:100A) MAX, Constant Current Charge up to 2.4VPC
Absorption : 0.1CA (SLR1000:100A, SLR500:50A) MAX, Constant Voltage Charge 60-90 mins
Float Application : Not Applicable

Example) Charge and Discharge Cycle
Discharge condition: DOD70% (0.1CA*6h)
Charging condition:
- Normal charge:
- 0.1CA for 6h, estimated 90%SOC
- Equalization charge:
- 0.025CA for 2.5h after charged (to 104% of rated capacity)

Efficiency of Discharge and Charge
- Approximately 88% at normal charge condition
- Approximately 83% at equalization charge condition
CAUTION
Charging the batteries with methods other than the method recommended by GS Yuasa may cause the
following adverse effects:
a) Overcharge: accelerates the decrease in electrolyte and corrosion of the grid frame of the positive
plates and shortens battery life.
b) Insufficient Charge: accelerates the deterioration of the active materials of the positive and negative
plates and shortens life.
5.1.2. Equalization Charging
These batteries may require periodic equalization charging shown in Table 4 below after standard charging.
Perform equalization charge under the following conditions (whichever comes first):

Every 20 days
