Battery Chargers & Testers

Dead batteries don’t schedule appointments. David’s Heavy Duty Tool Sales carries over 130 heavy duty battery chargers, jump starters and testers built for commercial trucks and fleet yards — equipment with the amperage to wake up a bank of Group 31s in the cold.

Commercial Battery Chargers

Our battery chargers range from bench-top maintenance units to wheeled shop chargers with boost modes for 12V and 24V systems. If your fleet runs multi-battery banks, we’ll match you with a charger that can actually feed them.

Charging System & Battery Testers

Guessing costs alternators. Our battery and charging system testers verify state of charge, cranking capacity and alternator output in minutes — so you replace the part that failed, not the one that was convenient.

Jump Starters & Booster Packs

For road service and yard moves, we stock professional jump starters and booster packs with the cranking amps to start heavy diesel engines — plus the cables and connectors that survive being run over.

Keep the Fleet Rolling

Veteran-owned and supplying trucking, construction and agricultural operations across North America since 2016. Order online or call 616.591.0095 — we’ll size the charger to your batteries, not the other way around.
