Battery Life Expectancy:
Battery life expectancy is dependent upon several variables and each location will be different.  Variables include climate, duration of each use, depth of discharge, how often used, the equipment attached to the battery and the preventative maintenance performed.  Therefore, Whelen Engineering recommends that the batteries be checked and inspected at least once a year.  Additionally, contacting the battery manufacturer for specific battery life expectancy information is also suggested.  For best performance, Whelen Engineering recommends that batteries should be replaced every two to three years.

Precautions: Please note that only trained and qualified personnel should handle, inspect and test batteries.  Before performing any battery service, it is recommended to contact the battery manufacturer and receive up to date MSDS sheets and safety precautions.  Open flame, sparks, heat or smoking in vicinity of batteries can be hazardous to life.  Ensure proper safety measures are fully understood, and proper precautions are followed.  Batteries may be heavy, improper planning and handling can be hazardous to personnel.
