## At a glance

- Provides battery state-of-health and state-of-charge information, along with voltage, current and CCA readings.
- Includes battery, cranking and charging-system checks, according to the listing.
- The tester draws power from the vehicle battery, so it does not need its own internal battery for testing.
- The listing describes an LCD with adjustable contrast and a backlight.

## Pros

- Combines battery-condition checks with cranking and charging-system diagnostics in one handheld tester.
- The stated support for several lead-acid battery types and rating standards offers flexibility across compatible 12V vehicles.
- Can be used with the battery in the vehicle or removed, according to the listing.

## Cons

- It is limited to 12V lead-acid batteries and is not intended for lithium, 6V or 24V systems.
- Testing depends on the vehicle battery for power, so the tester is not a standalone battery-powered unit.

## Before you buy

- The listing details are inconsistent or unconfirmed: the title gives a 100–2000 CCA range, while other copy specifies a 30–200Ah battery range, and the details section labels the power source as battery-powered while the usage description says it draws power from the vehicle battery. Confirm the applicable rating range and power arrangement for the selected listing.
