4.8 Battery Care and Backup Battery Calculations
4.8.1 Caring for Sealed Lead Acid Batteries
Sealed lead acid batteries are designed to operate in standby service for approximately five years.
This is based upon a normal service condition where there is an ambient temperature of 20
degrees C (68 degrees F) and batteries are completely discharged once every three months.
Length of service life is directly affected by the number of discharge cycles, depth of
discharge, and ambient temperature.
Use Guidelines
Avoid installation and/or operation in close proximity to heat sources. While the operating
temperature range is 0 to 49 degrees C (32-120 degrees F), battery life is maximized at an
ambient temperature of 20 degrees C (68 degrees F).
Batteries may generate ignitable gases. Because of this, install batteries in a well-ventilated
location, away from spark producing equipment.
DO NOT install batteries in an atmosphere where organic solvents or adhesives may be present.
DO NOT clean the batteries with oils, thinners, or similar substances. The case and cover of the
batteries are ABS plastic resin, which may suffer damage from these chemicals.
DO NOT install batteries in a heavy vibration or shock location.
ALWAYS wear insulated gloves when handling batteries.
DO NOT use together batteries of different capacities, age, or manufacture.
WARNING: DO NOT crush, incinerate, or dismantle batteries.
The electrolyte contains sulfuric acid, which can cause serious damage
to eyes and skin. If contact does occur, flush with water and seek
immediate medical attention.
4.8.2 Storing Batteries
For batteries that are to be stored for an extended period of time, give a supplement charge
monthly.
NEVER store batteries in a discharged condition.
The self-discharge rate of batteries is approximately 3% per month when the storage temperature
is maintained at 20 degrees C (68 degrees F). The self-discharge rate varies depending upon
temperature. Cooler temperatures cause the self-discharge rate to decrease. Warmer temperatures
cause the self-discharge rate to increase.
