## At a glance

- Checks 12V lead-acid battery health, cranking and charging systems.
- Listing describes support for Regular-Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB batteries within 100-2000 CCA.
- Retains the most recent test result for review, according to the listing.
- Uses battery-terminal power, so no separate power source is listed.

## Pros

- Combines battery-health, cranking and charging checks in one device.
- The compact listed dimensions and 215 g weight make it practical to keep with vehicle tools.
- Data review can help compare against the most recent test without repeating it immediately.

## Cons

- Limited to 12V batteries according to the product description, so it is not presented as a tester for 6V or 24V systems.

## Before you buy

- The listing gives a battery-terminal minimum operating voltage of 12 volts but also says testing stops below 8V and advises charging before retesting. These voltage details are inconsistent, so check the manual for the operating threshold. It also describes multiple battery chemistries and a 100-2000 CCA range as applicable to most listed lead-acid batteries, not every battery or vehicle. Turn off the ignition for battery testing and follow the manual's safety instructions.
