The Powerware BMA monitors individual battery voltage continuously to determine condition and charge. If a problem is detected during float service, discharge or recharge, the Powerware BMA sounds an alarm to alert you of a potential failure in your backup power.

A 1,000 event alarm history enables you to track battery discharges, recharges, temperature conditions and low/high-voltage batteries. Only by tracking the condition of your batteries can you be sure that your UPS' critical load will be supported during a power disturbance.

Installation is included in the price of the cost-effective BMA. (There is an additional cost for installation at sites located further than 100 miles from an authorized service center.)
