The Battery Informer™ is the smartest, most accurate and cost effective battery State-of-Health (SOH) indicator in the industry. If you can read, you can now easily evaluate if your batteries will perform as required. The Battery Informer™ is intelligent and automatically learns each individual battery's baselines. It then measures the ohmic reading every day and trends that measurement to the individual baseline. Compensating for temperature it iconically displays the battery status as " GOOD", "WARNING", or "FAILED", based on IEEE standards. The Battery Informer™ was designed to lower your cost of battery maintenance while increasing the reliability of your back-up power system.
