SAFETY PRECAUTIONS
(1)
When a sulfuric acid contact with skin
For acid contact with skin, eye or clothing, flush with water immediately. If swallowed, drink a large
amount of water or milk. Seek medical attention immediately. When handling acid, always wear
eye goggles or a face shield and rubber gloves.
(2)
Strict prohibition of fire and ventilation
Since batteries generate explosive hydrogen gas, no fire should be drawn near. Before the battery
charging, keep the battery cover open and check the ventilation status. Charging in an enclosed
space can cause a explosion.
Never place metallic articles on the batteries
(3)
If done so, it may cause "short circuit" accidents(dangerous especially while charging).
Sparks will be generated which is equally dangerous as open fires.
(4)
Handling of charger
When connecting or disconnecting a battery from a charger or attempting maintenance, make
sure switches are all off. Ensure that the charger and the battery are matched. If a 300Ah battery
is used with a charger designed to charge a 500Ah battery, it will severely overcharge the battery.
5)
OPERATION PRECAUTIONS
Avoid over-discharge
(1)
If over-discharged, it will be difficult to restore the batteries to the original state by recharge. In
order to maintain the batteries in use for long period of time, it is recommended to use the
batteries with discharge amount not exceeding 80% of the rated capacity. Further care should be
taken for preventing the unit cell voltage from falling below 1.5V.
Avoid over-charge
(2)
If overcharged, the rise in battery temperature will become excessive, resulting in deterioration of
plates and other parts and markedly shortening of battery life.
(3)
Avoid excessive elevation of temperature
Be sure to open the cover of battery housing tray before charging. If there is a possibility of
temperature to exceed 55
current.

Unpacking
Electric traction storage batteries(herein after refer to as "batteries") are delivered to customers in
dry-charged condition. At unpacking, check whether the batteries and accessories have been
damaged. If there are observed defects, you should notify the condition to our branch office or
agent. Never remove the sealing plug until the battery is put into service.
C, discontinue the charge operation temporarily, or reduce the charge
