Battery & Charging Systems Testers
“It needs a battery” is a $200 guess; a tester makes it a fact. We stock over 40 battery testers and charging system analyzers for 12V and 24V truck electrical systems — verify batteries, alternators and starters in minutes, before parts get thrown at the problem.
Test the Whole Charging Circuit
Good analyzers check more than state of charge: cranking capacity under load, alternator output and ripple, and voltage drop across the system. That’s the difference between replacing the failed part and replacing parts until it starts.
Fleet-Grade Testing
Multi-battery banks need testers that understand series-parallel configurations. Ours do — and they print or store results, so PM records show battery health trending before failures strand trucks.
Complete the Battery Bay
Pair testers with our commercial battery chargers and the full battery chargers and testers line.
