B2-1 Safety and Warnings
-
-
-
-
-
-
-
The battery should be away from heat source
and the place that is easy to produce sparks,
the safety distance should be greater than
0.5m.
The battery should avoid direct sunlight,
and cannot be placed in the environment
with large amount of radioactivity, infrared
radiation, ultraviolet radiation, organic solvent
gas and corrosive gases.
Due to the high voltage of battery componen-
ts, there is risk of electrical shock; therefore,
insulated tools should be used when
installing or removing the conductive straps,
wear insulated gloves, aprons and protective
goggles when installing or handling batteries.
During installation or handling of the batteries,
only non-metallic sling can be used, wire
ropes cannot be used.
Dirty strap or loose connection may cause
battery ignition, or even damage the battery
group, so double-check and remove the dirt
on the strap when installing, and tighten the
strap.
DO NOT clean the battery case with organic
solvent, DO NOT use carbon dioxide fire
extinguisher to extinguish electrical fires,
carbon tetrachloride fire extinguisher is
available.
When the battery is connected to the charger
or the load, circuit switch should be at "OFF"
position, and make sure the connection is
correct: positive electrode of the battery
is connected to the positive electrode of
the charger, and negative electrodes are
connected with each other.
During the use of battery, be sure to tighten
the bolts of the terminals, so as to avoid
sparks and poor contact.
As for failure to comply with instructions for use,
maintenance without using origi-nal parts, user
corruption, or violation of provisions when adding
electrolyte and other circumstances, the quality
assurance will automatically void.
B2-2.1 Pre-use Checks
-
-
-
-
-
Check if the fixing bolts on the bracket for the
battery are tightened, insecure installation
may cause damage to the case due to the
shock during the travel of the vehicle.
Metal objects should not be placed on the
battery to prevent short circuits;
Check if the poles and wiring connections are
reliable from time to time. In order to prevent
oxidation of terminals, you can apply Vaseline
or other protective agents;
DO NOT check the capacity of battery
through direct ignition (short circuit test), such
method may damage the battery;
There will often be yellow white paste around
the battery poles and cover, which is caused
by the corrosion of sulfuric acid to the poles,
wire clips and holders, etc. These substances
are of very large resistance and must be
removed in a timely manner;
When you need to use two batteries in
series, the capacities of the two batteries are
preferably to be equal. Otherwise it will affect
the service life of the battery.
B2-2 Use of Battery
B2-2.2 Discharging
-
-
-
-
When connecting or disconnecting the battery
connector (such as, plug), the power supply
must be disconnected first;
In order to meet or exceed the rated bat-
tery service life, the battery should avoid
excessive discharge during runtime (the
remaining capacity is less than 20% of the
rated capacity);
Re-charge the battery immediately after
discharging without delay;
The normal load voltage of battery is 20.8V
~24.4V, if the voltage is lower than this range,
it indicates that the battery already has
capacity loss, the circumstance of long time
under load voltage may reduce the service
life of the battery.
