If the power system is not powered on and does not supply power to any load for more than

Basic Precautions
Before installing and maintaining the battery, note the following:
Do not wear metal articles such as wristwatch, hand chain, bracelet, and ring.
Use special insulated tools.
Take care to protect your eyes when operating the device.
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.
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.
