Universal 12 V battery tool

The LUOM KW510 combines a conductance battery tester, a fully automatic 5 A charger and a pulse-repair maintainer in one handheld unit. Its colour LCD and button interface give clear voltage, internal-resistance and cold-cranking-amp readings for 12 V lead-acid and lithium-ion batteries. The tester covers 100–2000 CCA and multiple rating standards without needing a separate analyser.

Fitment and workflow

Clamps connect directly to the battery posts on cars, motorcycles, ATVs, lawn tractors, trucks, SUVs or marine craft, so no special adapters are required. The charger can start from as low as 2 V and tops out at 12 V 5 A, letting you recover deeply discharged cells before switching to trickle or maintenance mode. Pulse desulfation runs automatically once sulphation or acid stratification is detected, freeing you from manual reconditioning steps.

Included accessories

The package supplies the tester-charger-maintainer body, heavy-duty clamp cables and a multi-language manual. No extra software, app or subscription is needed; all diagnostics, charging profiles and repair cycles are selected on the device itself. The compact 7.68 × 5.83 × 2.72 in, 1.46 lb enclosure stores easily in a tool bag or glove compartment.
