Services - Battery Capacity Testing

IEEE 500-1984 states that 98% of battery failures are degradation type failures. These types of failures can be detected through a comprehensive testing program. By incorporating a battery testing program, battery failure rates decrease by a factor of 267% as reported by IEEE 500.

A Battery Capacity Test, is the only "true" method recognized by the IEEE and many manufacturers in determining a batteries functional state.

Recommended Testing Intervals:

When the battery has reached 85% of its service life, it should be tested annually.

When a battery's capacity decreases more than 10% from the previous test or it's capacity is less then 90%, the system should be tested annually.

IEEE P1184 specifies annual tests for the UPS battery systems.

Valve regulated batteries should be tested every 12-18 months in accordance with the IEEE-1188. This is due primarily because of the lack of other means in determining the battery's "condition" and VRLA batteries are often more prone to "unexpected" failure.
