Installation, Commissioning and Maintenance
Installation
The ground shall be strong enough to back up
load.
Batteries integrated in equipment should be
compliance with the installation instructions,
separately installed on rack and cabinets should
be connected by bolts to the foundation.
Battery racks or cabinets should be properly
installed according to instructions.
Connecting
Before connecting, make a overall check of all
the batteries and connectors to see whether
there is hardware damage or manufacturing
defects in order to guarantee the polarity are
correct.
The charge equipments are in cut-off state and
without loads, then connect the positive and
negative terminals to chargers.
During the installation and transit of the battery,
use insulted tools, gloves, aprons and safety
glasses; do not touch connecting terminals and
safety valve in transit.
Placing tools and conductive articles on the
battery is strictly prohibited.
Maintain the connecting terminals clean and
tighten the connectors as per required torque
value.
Commissioning
Assure battery operation in the clean
environment;
At 20
℃
, charge the battery with 2.24Vpc for 16 to
24 hours, or with 2.35Vpc for 8 to 12 hours;
charge voltage should be adjusted according to
the ambient temperature.
Maintenance
Monthly maintenance:

Measure and record the ambient temperature
of the battery room, battery container and
terminals.

Check container, lid and terminal surface
defects and temperature of each battery.

Measure and record the total voltage and
floating current of the battery system.

Correct problems once found.
Quarterly Maintenance:

Repeat every item of monthly inspection.

Measure and record floating voltage of every
on-line battery.
Annually Maintenance:

Repeat quarterly maintenance and inspection.

Check whether the connectors are loose or
not.

Check whether the safety valve is tight or not.

Perform a discharge test to check the exact
load every year and discharge 30~40% of the
rated capacity.
Three-year Maintenance:

Carry out a capacity test(C
10
) every three
years and every year after six years' of
operation. If the capacity of the battery is lower
than 60% of the rated capacity, the battery
should be replaced.
Security Instruction

Only professionals shall be allowed to open
and maintain the battery with insulated tools;
Any metal objects to be put on top of the
battery shall be strictly prohibited;

The battery should be stored and installed
upright; upright down or on one side is
prohibited;

Please do not use any organic solvent to clean
batteries;

Please do not smoke or set out fire near
batteries;

Please do not remove the relief valve or put
anything into the battery;

Please charge the battery within 24 hour after
the discharge;

Long storage time would result the
degeneration of battery performance, and
suggest use the battery early.
