Standard battery capacity analyzers verify the battery health of electrical backup power systems by applying DC current to the terminals to perform a load test, then displaying the remaining available voltage. Applications include UPSs, security systems, and fire alarms.

Battery capacity analyzers with record storage connect to a computer to transmit or export data for analysis, recordkeeping, and storage. These analyzers verify the battery health of electrical backup power systems by applying DC current to the terminals to perform a load test, then displaying the remaining available voltage. Applications include UPSs, security systems, and fire alarms.

Battery impedance testers apply an oscillating AC current signal to the terminals, observe the resulting voltage drop, and calculate the impedance, or resistance, in Ohms. This measurement determines connection resistance between cells and cell voltage for a more comprehensive look at battery health when compared to other battery testers. Applications include UPSs, security systems, and fire alarms.
