Installation And Care Of Sealed Lead Acid Batteries - Wheelock PSC-2420-B Installation Instructions Manual

INSTALLATION AND CARE OF 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 of 20 degrees C (68 degrees F) and batteries are completely discharged once every three months.
LENGTH OF SERVICE LIFE WILL BE DIRECTLY EFFECTED BY THE NUMBER OF DISCHARGE CYCLES, DEPTH OF
DISCHARGE, AND AMBIENT TEMPERATURE.
Use Guidelines:
1. Avoid installation and/or operation in close proximity to heat source. While the operating temperature range is 0 to 49 degrees C
(32-120 degrees F), battery life will be maximized at an ambient of 20 degrees C (69 degrees F).
2. Batteries may generate ignitable gases. Because of this, batteries shall be installed in a well ventilated location, away from spark
producing equipment.
3. Batteries shall not be installed in an atmosphere where organic solvents or adhesives may be present. The batteries shall not be
cleaned with oils, thinners, or similar substances. The case and cover of the batteries are ABS plastic resin which may suffer
damage from these chemicals.
4. Batteries shall not be installed in a heavy vibration or shock location.
5. Batteries shall have a 1/4" minimum separation between cells.
6. Insulated gloves shall always be worn when handling batteries.
7. Batteries shall not be crushed, incinerated, or dismantled. 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.
8. Batteries of different capacities, age, or manufacturer shall not be used together.
Battery Storage:
Batteries which are to be stored for an extended period of time should be given a supplementary charge monthly. Batteries should
never be stored in a discharged condition.
The self-discharged 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 will vary depending upon temperature. Cooler temperatures cause the self-discharge rate to
decrease. Warmer temperatures cause the self-discharge rate to increase.
