Storage Battery

Before operating storage batteries, carefully read the safety precautions for battery handling and connection.

Improper handling of storage batteries causes hazards.

When operating storage batteries, avoid short circuit and overflow or leakage of the electrolyte. Electrolyte overflow may damage the device. It will corrode metal parts and circuit boards, and ultimately damage the device and cause short circuit of circuit boards.

If the power system is not powered on and does not supply power to any load for more than two weeks, turn off all battery loops.

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.

Hazardous Gas
  • 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.
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

If the electrolyte overflows, absorb and counteract the electrolyte immediately.

When moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte may hurt human bodies. When you find the electrolyte leaks, use the following substances to counteract and absorb the leaking electrolyte:

  • Sodium bicarbonate (baking soda): NaHCO3
  • Sodium carbonate (soda): Na2CO3

Select a substance to counteract and absorb the leaking electrolyte according to the instructions of the battery manufacturer.
