CB121200 12V 120AH High Capacity Lead Acid Battery Non Spillable Maintenance Free

Sealed Construction
The unique construction and sealing techniques of the battery guarantee leak
proof operation in any position with no adverse effect to capacity or service life.
Electrolyte Suspension System
All batteries utilize an electrolyte suspension system consisting of a high
porosity, glass fiber material which in conjunction with plates, totally absorb and
contain the electrolyte.
Gas Recombination
CGB batteries incorporate a built-in design that controls gas generation and
induces recombination of more than 99% of gases generated during float or
cyclic usage.
Maintenance Free Operation
Due to the perfectly sealed construction and the recombination of gasses within
the cells, the battery is almost maintenance free.
Low Pressure Valve Regulated System..
All batteries are equipped with safety release valves, designed to operate
between 1.5 and 6 psi (10-40kPa) and automatically reseal. Hence, there is
never an excessive accumulation of gas within the battery.
Heavy Duty Grids
Heavy duty lead calcium tin alloy grids provide an extra margin of performance
and service life in either float or cyclic applications.
Cyclic Service Life
More than 600 discharge/recharge cycles can be realized from CGB CB and HR
batteries, dependent on the average depth of discharge.
Float Service Life
SE and CB, HR Series batteries have an expected life span of 3 to 5 years in
float service applications.
Self Discharge - Shelf Life
The self discharge rate at room temperature is approximately 3% of rated
capacity per month.
Operating Temperature
CGB Batteries may be operated over a broad range of ambient temperatures.
Deep Discharge Recovery
The batteries recover their capacities even after repeated deep discharges

Batteries should be stored in dry and clean warehouse which has good air
exchange system. Batteries should avoid direct sunlight. Batteries should not
be near to heat (such as radiator, the distance should more than 1m). Batteries
should avoid any toxic gas and organic solvent.
When the ambient temperature is less than 25℃, the longest storage life is 6
months. If ambient temperature is higher, the longest storage life varies as
specified in below chart.

Storage Temperature (℃)




Storage Time (Month)





Batteries should be recharged within the storage life or before using.
Charging methods: maximum charging current 3.0A, constant voltage
2.45±0.05V/cell (25℃);
Charging time: 15~20h; Temperature compensation coefficient: -5mV/℃/cell.
