Stationery Battery Maintenance

These batteries are maintenance-free and not much cleaning or topping of water is required, as compared to a flooded cell. As it is challenging to determine the health of your battery system by following traditional maintenance techniques that only provide voltage and current data, Tristar Power Systems uses the state-of-the-art Medtronic’s battery analyzer to trend and monitor the battery conductance values.

Most of the VRLA carry a design life of 5, 10, or 20 years from the manufacturers, who normally warrant 1, 3, and 5 years-full and the rest pro-rata. Manufacturers honor these warranty claims only when you are able to produce evidence the batteries were serviced or maintained continuously by a service provider. In the event of no maintenance history, battery manufacturers may refuse to honor warranty replacements.

At Tristar Power Systems, we follow the IEEE Recommended Practice for Maintenance, Testing, and Replacement of Valve-Regulated Lead- Acid (VRLA) Batteries for Stationary Applications.

Our maintenance procedures include environmental checks, testing all cells with a Midtronics battery analyzer, checking cell temperatures, checking torque, checking specific gravity, ripple voltage, ripple current, charge, voltage, equalize voltage and more…

Readings obtained during the preventive maintenance are provided to our customer via web-enabled reports, thereby allowing comparison with previous test results.

Why Batteries Fail? Following are the most common reasons why a battery fails prematurely.

    Installation problems (improper mounting, loose connections on terminal, improper torque)

    Improper charging (voltage/current)

    Excessive discharge/charge cycling

    Ambient temperature (batteries not installed in a temperature-controlled environment)

    Manufacturing defects
