Professional 12V Battery Analyser

The Konnwei KW210 is a digital battery tester built for workshops and DIY owners who need fast, accurate health checks on 12-volt lead-acid batteries. It covers starting, deep-cycle and marine types across flooded, AGM, EFB, gel and maintenance-free chemistries. The colour screen and multilingual menu make it straightforward for technicians and enthusiasts alike.

CCA 100–2000 and 30–200 Ah range

The analyser measures cold-cranking amps from 100 to 2000 and capacity from 30 to 200 Ah, handling typical car, van and light-truck batteries with headroom to spare. It operates on DC 8 V to 16 V, so it draws power directly from the battery under test. Very large commercial or dual-battery banks above 200 Ah fall outside the supported range.

USB updates, PC printing and data review

A USB cable provides lifetime firmware upgrades and lets you print detailed battery reports on a PC. Results including SOH, SOC, CCA value and internal resistance can be stored, reviewed and graphed in real time on the device. No wireless connectivity or mobile app is included, so buyers needing remote logging should look elsewhere.

Questions about this item

Will the KW210 work with the 12V lead-acid battery I already have in my car?

How can I confirm the KW210 is reading correctly once I connect it?

The colour screen shows real-time voltage graphs, internal resistance in milliohms, SOH and SOC percentages, plus a clear Good or Replace verdict after each test.

Does the KW210 come with the USB cable needed for PC printing and firmware updates, or must I buy one separately?

The USB cable for lifetime upgrades and PC report printing is included in the box.
