ELECTRICAL DEVICE
Attention of Operation
ϠʳBattery electrolyte contains sulfuric acid, which can cause severe burns. Avoid
contact of skin, eyes, or clothing
ϠʳWhen sulfuric acid water spill into clothing will stick to skin. Take off the clothing
and flush with water.
z
Battery can be charged and discharged. Without charging, the battery will have
less lifetime.
z
If the battery have short circuit inside, both terminal will not have voltage existed.
z
Besides, the regulator rectifier lost the function and shorter lifetime.
If the battery stay too long without use, it will lost power and have less capacity.
The battery need to charge each 2~3 months.
z
After fill up the electrolyte, the new battery will generate voltage. It’s necessary
to recharge if the voltage is low. It’s necessary to leave the battery for more than
20 minutes before sealing the cap. It will increase the lifetime of new battery if
recharged before installed.
z
Do not unplug the electrical components from wire hardness when the current is
working. This will cause too high of voltage and damage other compounds such
as rectifier, light bulbs…etc. Turn off the main switch to OFF before the
operation.
z
z
z
The Maintenance Free battery does not need to refill electrolyte or water.
All charge system needs to be installed before check.
Do not use quick charge unless it’s in urgent.

The battery needs to be taking out from vehicle when doing charge work.
When checking the voltage, must use the electrical meter.
