Easy-to-understand good/fail judgment
Easy selection of CCA value using JIS/CCA conversion table on the back
Compatible with start-stop battery
JIS / DIN / EN standard measurement and judgment possible
Charging system test function (alternator check) also included
Internal resistance (internal impedance) measurement displayed
Immediate determination of discharged batteries without recharging
Waterproof specification (IPX6) to prevent water damage failure
LCD with backlight
Patented "Single Load Dynamic Resistance", a world-class proprietary technology

Accurate diagnosis to avoid battery problems

SOH, SOC, internal resistance measurement

Smallest and lightest in its class

The smallest design that fits in your pocket despite its high performance
Smallest and lightest in its class, compact enough to fit in a pocket. It is not bulky in the tool box, enabling staff to carry it with them at all times and facilitating their work.

Industry's first IPX6 waterproof rating

Resistant to accidental water damage
Conforms to IPX6, a world first for a battery tester. Measurements can be made without worrying about malfunctions due to wetting of the device, even when used outdoors in rainy or stormy weather, rescue scenes, marine scenes, and so on. Dirt from the operation can be easily washed out with water.

Easy to see in the dark

Backlit LCD screen
Diagnostic results can be checked without the need for external lighting when measuring batteries at night or in the dark, or even when measuring batteries located deep under the hood, in the trunk, or in the back of the living room. Smooth and stress-free diagnosis in any situation.

Simple operation

Intuitive operation and easy to understand diagnostic results.
GOOD & PASS: Battery is good and has sufficient charge.
GOOD & RECHARGE: Battery is good but needs to be recharged.
RECHARGE RETEST: Battery is discharged and cannot be determined.
BAD & REPLACE: Battery has deteriorated or short-circuited cells. Replace immediately.

CCA/JIS conversion table included

No need to look up, no need to get lost.
The back of the unit comes with a CCA/JIS conversion table. Quick battery measurement is made possible by quickly checking the code corresponding to the battery.

Clamps are fully covered and insulated

Safety design to prevent unexpected short-circuit.
Clamp fittings are fully covered with plastic. Prevents short-circuiting in the event of unintentional contact with metal surrounding the battery.
