A nationwide network of battery charger repair service providers is available through the ARS-authorized repair center network. Also available for certain types of battery-charging systems is an off-site repair service through Rathbone Energy Services.
Regardless of which service provider is being contacted for service of a battery charger, ensure that any selected provider actually works on the particular type of charging system that is in need of service. Lithium ion, nickel cadmium, lead acid, six- and 12-volt, and three-phase systems all have different repair costs and distinct requirements. Not all service providers provide expertise in repairing all types of battery-charging systems.
