Fast and accurate, the Midtronics GRX-3000 Battery Diagnostic System can determine, often in less than five minutes, the difference between a recoverable battery and one that is not. Defective batteries with open welds and shorts are rapidly identified and recoverable batteries are safely and quickly charged. Diagnostic charging sessions are customized and controlled. Charging stops as soon as batteries can be returned to customers, or are determined to require replacement. The GRX diagnostic station delivers efficiency in the shop and more accurate preventative maintenance decisions by helping to eliminate guesswork and wasted time charging defective batteries.
