APS field service staff has the skills necessary to inspect and maintain your battery system. Based on IEEE battery capacity testing standards we perform internal resistance testing to base our evaluation of your string. We carry both industry leader Alber (Cell Corder) and Midtronics testing equipment to deliver detailed reports in relation to your battery strings condition. If you desire around-the-clock monitoring of your critical systems, we can install battery monitors: Alber, Cell Watch, and B-Tech just to name a few. For capacity testing or load testing we have an Alber BCT 2000 & 900 AMP Load Bank (24VDC to 125VDC, with monitoring of up to 256 cells), and a Canon 48VDC Load Bank.
