  • Page 34: Electrical Hazard

    Lucent Technologies Round Cell Batteries Electrical Batteries differ from other sources of power in that they are delivered to the points of installation as live units. A battery gives no indication by Hazard its appearance of the potential energy stored in it. Batteries have enormous short circuit capability that can result in serious burns or create dangerous projectiles from the object causing the short circuit.
  • Page 35: Shock Hazard

    Lucent Technologies Round Cell Batteries Electrical • Exercise extreme care to avoid any short circuits across the battery terminals. Hazard, continued • In a grounded battery system, use extreme care not to short any metal objects from the ungrounded battery terminal to ground (which can include the equipment metal chassis, building structure, cable racks, etc.).
  • Page 36: Battery Gases

    Lucent Technologies Round Cell Batteries Battery Gases Lead-acid batteries produce hydrogen gas even under normal charging and open circuit conditions. Boost charging or abnormal conditions, such as high temperature, abnormal charging, shorted cells, etc., can produce greater amounts of gas. If not permitted to escape, this gas can build up to explosive concentrations.
  • Page 37 – Disconnect at the load or charger first before disconnecting at the battery terminals. Note: Lucent Technologies recommends not making connections to the battery terminals while the circuit is attached to a power source or load. However, some circumstances may require personnel to replace cells within a string while the string is still connected to the load/charger to avoid interruption of service.
