Charging
Standby use: Apply constant voltage charging at 2.275 volts
per cell (or 2.25–2.30VPC).
Cyclic use: Apply constant voltage charging at 2.40-2.50 VPC.
Initial charging current should be set at less than 0.25CA.
Top charge: Product in storage (ambient temperature 25°C/77°F)
requires a top charge every six months. Apply constant voltage at
2.40 volts per cell, initial charging current should be set at
less than 0.1CA for 15 to 20 hours.
Discharge
Stop operation when voltage has reached the minimum
permissible voltage. Recharge immediately.
Do not operate at 6CA or more current continuously.
Storage
Always store battery in a fully charged condition.
If battery is to be stored for a long period, apply a recovery
top-charge every 6 months.
Store batteries in a dry and cool location.
Temperature
Keep within ambient temperatures of –15°C to +50°C
for both charging and discharging.
Incorporating battery into equipment
Encase battery in a well ventilated compartment.
Avoid installing battery near heated units such as a transformer.
House the battery in the lowest section of the equipment
enclosure or rack to prevent unnecessary battery temperature rise.
Others
Avoid terminal short circuit.
DO NOT expose to open flame.
Avoid setting batteries in environments which can cause
direct contact to gasoline, paint thinner, organic solvents,
synthetic resins, oil, etc.
