Short Circuit
Battery short circuit may cause human injuries. Although the voltage of ordinary batteries is
low, the instantaneous high current caused by the short circuit releases a great deal of energy.
There is danger of explosion if the battery is incorrectly replaced. Therefore, replace the
battery only with the same or equivalent type recommended by the manufacturer.
Keep away metal objects, which may cause battery short circuit, from batteries. If metal
objects must be used, first disconnect the batteries in use before performing any other
operations.

Battery Temperature
If a battery overheats, the battery may be deformed or damaged, and the electrolyte may
overflow.
When the temperature of the battery is higher than 60° C, check the battery for electrolyte
overflow. If the electrolyte overflows, absorb and counteract the electrolyte immediately.
Battery Leakage
Issue 02 (2019-02-26)
Wear rubber gloves and a protective coat in case of electrolyte overflow.
When handling a storage battery, ensure that its electrodes are upward. Leaning or
reversing the storage battery is prohibited.
Do not wear metal articles such as wristwatch, hand chain, bracelet, and ring.
Do not use unsealed lead acid storage batteries. Lead acid storage batteries must be placed
horizontally and stably to prevent the batteries from releasing flammable gas, which may
cause fire or erode the device.
Lead acid storage batteries in use emit flammable gas. Therefore, ventilation and
fireproofing measures must be taken at the sites where lead acid storage batteries are used.
