Battery Tester for 6V 12V 24V Systems

The OBDResource BR502 tests 6V 12V and 24V lead-acid batteries rated from 100 to 2000 CCA. It reads voltage, internal resistance, state of charge and state of health on a 1.8-inch HD screen. The analyser works on flooded, AGM flat plate, AGM spiral and gel types found in cars, SUVs, pickups, motorcycles, boats and trucks. Results appear within two seconds with 99.6% accuracy.

Suits DIY owners and workshops needing quick

Technicians who require a printable report or data-logging function will not get that feature here. Users who must test lithium-ion or high-voltage traction packs should look at a different instrument. The tester is powered by the battery under test so no separate supply is needed.

Tests 100-2000 CCA range on 1.8-inch HD display

The single figure that decides fit is the 100 to 2000 CCA measurement window. If the battery falls outside that range the BR502 cannot return a valid result. The built-in microprocessor applies the selected CCA standard and shows Good, Normal or Poor within seconds.

Questions about this item

Does the BR502 need calibration or new clips over time?

The tester is battery powered and has no user-replaceable parts listed; keep the clips clean and store the unit dry to maintain the 99.6% accuracy spec.

What stops a long testing session first — heat, battery drain or the 1.8-inch screen?

The unit draws power from the battery under test, so the limiting factor is the vehicle battery’s own state of charge, not internal heat or display runtime.

How much heat or noise does the BR502 produce during all-day use in a garage?

It has no fan or moving parts, runs silently and generates negligible heat; the only power used is the tiny draw needed for the microprocessor and 1.8-inch HD screen.
