Datasheet

 Description:

High performance and long service life of UNICELL batteries depend upon correct charging. Improper charging modes or inadequate charging equipment result in decreased battery life and or unsatisfactory performance. Any of the conventional charging techniques may be used, but to obtain maximum service life and capacity, along with acceptable recharge time, constant current/constant voltage charging is recommended. A charge quantity of 105-120% of the previous discharged quantity is needed for fully charging the battery. The charging voltage of battery decreases with increasing temperature and increases with decreasing temperature. At a temperature below 5 C (41 F) or above 35 C (95 F), the temperature compensation for charging voltage is necessary. At ambient temperature the compensation will not be necessary

Overcharging should be avoided: As a result of too high a charge voltage, excessive current will flow after reaching full charge, causing decomposition of water in the electrolyte and hence, premature aging. Undercharging should also be avoided: if too low a charge voltage is applied, the charger current output will essentially stop before the battery is fully charged. This allows some of the lead sulphate to remain on the plates which will eventually reduce capacity.

HANDLING INSTRUCTION

# Do not short the terminals.

# Do not place the battery near or in fires

# Do not use the battery in a container or bag without proper ventilation

# Operate at a temperature between -15 C . To 50 C. But for cycle use , the 5 C to 35 C temperature range is recommended.

# To properly store the battery, remove battery from equipment or charger and store in a dry and cool place

# Immediately recharge after discharging

# If sulfuric acid from the battery is spilled on skin or clothing, wash immediately with water. If acid comes in contact with eyes , flush with large amounts of water and immediately see a doctor. # To obtain maximum life, the ripple current at the r.m.s. Current of charger should be regulated to less than 0.1C (A) # Avoid mixed use of battery. Different capacities , histories or manufacturers of batteries may cause damage to the batteries or other equipments.
