Battery Safety

Battery Safety

Before installing, operating, or maintaining the batteries, read the battery manufacturer's safety instructions. Observe the safety precautions provided in this section, which are supplemental to the safety instructions provided by the battery manufacturer.

Basic Requirements

  • Avoid skin contact with battery electrolyte. Before handling batteries, wear goggles, rubber gloves, and protective clothing.
  • When handling a battery, ensure that its electrodes always point upward. Do not tilt or overturn batteries.
  • Before installing or maintaining batteries, switch off the battery circuit breaker or remove the battery fuse.
  • Install batteries in a dry, clean, and ventilated environment that is free from sources of ignition. Do not expose batteries to sunlight or water.
  • Ensure that the load-bearing capacity of the floor in the installation area is sufficient. Install additional supports if required.
  • Secure battery cables to the torque specified in the battery documentation. Loose connections will result in excessive voltage drop or cause batteries to burn out in the case of excessive current.
  • Ensure that battery cables do not come in contact with water.

Battery Short Circuit

High short circuit currents or electric shocks can cause equipment damage, personal injury, or death.

To prevent short circuit or electric shock, disconnect the batteries before performing any operation or maintenance.

Flammable Gas

  • Do not use unsealed lead-acid batteries.
  • Lead-acid batteries emit flammable gas. Therefore, place and secure lead-acid batteries horizontally to prevent fire or corrosion.

Store lead-acid batteries in a place with good ventilation, and take fire safety precautions.

Battery Leakage

High temperatures may result in battery distortion, damage, and electrolyte overflow.

If the battery temperature is higher than 60°C, battery electrolyte may overflow. If the electrolyte overflows, wear goggles, rubber gloves, and protective clothing and absorb the leaking electrolyte using sodium bicarbonate (NaHCO3) or sodium carbonate (Na2CO3). Do not transport or move batteries if there is an electrolyte leakage.

Battery Overdischarge

After connecting the batteries, remove the battery fuse or turn the battery circuit breaker OFF and then power on the power system. This prevents battery overdischarge. After the power system is on, replace the battery fuse or turn the battery circuit breaker ON.
