● 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.

TIPS AND PRECAUTIONS
CGB CB, HR and SE Series batteries are truly efficient maintenance
free electro-chemical systems and are designed to provide years of
trouble free service. Their performance and service life can be
greatly maximized by observing the following guidelines.
• Heat kills batteries. Avoid installation and/or operation in
close proximity to heat sources of any kind. While the operating
temperature range is -15°C to 45°C, and ideal service life will be
realized when the battery is operated in an ambient temperature of
20°C (for cyclic service applications, a range of 5°C to 35°C is
• If the battery is to be installed in an air or water tight
container, ventilation must be provided. Batteries may generate
ignitable gases which must not be contained. Because of this,
batteries should not be installed near spark producing equipment.
• Avoid installing the battery in an atmosphere where organic
solvents or adhesives may be present. Do not clean the battery with
oils, thinners or similar substances. Use water only. The case and
cover of the battery is ABS plastic resin which may suffer damage
from these chemicals.
• Soldering to the battery terminals is NOT recommended. If
soldering is unavoidable, it must be accomplished within 3 seconds,
using a maximum 100 watt soldering iron.
• If installed in a heavy vibration or shock application, the
battery must be securely fastened with shock absorbing materials.
• Provide free air space between batteries when more than two are
grouped together. The recommended distance is 0.2" to 0.4" (5mm to
• Always wear insulated gloves when handling batteries; especially
when series and parallel connecting groups of batteries.
• When batteries are connected together in a series parallel
arrangement, the inter-connecting cables must be of equal length
and resistance to insure equalization of the load.
• For maximum life expectancy, the R.M.S. ripple current should be
regulated to no more than 0.1C (10% of battery's rating).
• Do not crush, incinerate or dismantle the battery. The
electrolyte contains sulfuric acid which can cause serious damage
to eyes and skin. Should this occur, flush profusely with water and
seek medical attention.
• Mixing batteries of different capacities, age and/or manufacture
is not recommended. Please consult with an application engineer if
it is unavoidably necessary.
• Battery life is dependent on its operating conditions. Please
refer to the life curves published in this Applications Manual.
These curves represent typical results under optimum operating
conditions. Actual life will vary greatly due to variability of
these conditions. To obtain optimum battery performance for standby
service, CGB recommends that within five years of use, the
batteries be replaced.
• Observe the external appearance of the battery. If, at any time,
cracks, deformation or other damage is found on the battery case or
cover, or if any leakage of the electrolyte is observed,
immediately replace the battery.
Note: If a battery with any irregular appearance as stated above is used
continuously, a decrease in capacity, leak age of electrolyte,
short circuits and a potential for a smoke and/or fire incident may
