The key to preventing battery failures is to minimize any misuse, perform scheduled routine maintenance, and track capacity. An annual capacity test on a battery plant is recommended to obtain a high degree of reliability. Battery load tests are considered by the industry to be the most effective method of determining a battery's ability to supportits the required load for the specified time period.
Capacity testing for -48V and +24V battery plants is performed per IEEE standards, which involves discharging each string of batteries separately utilizing a load box. The Emerson Network Power Intelligent Battery Load Tester automatically logs voltage and current measurements throughout the discharge and features 200 amps of built-in power for battery recharging.
