Wireless Bluetooth battery tester. Pairs with your smartphone to test and log battery health.
The BK100 has no screen — it is entirely app-based. Clip it to the battery terminals, open the Konnwei app on your phone, and all test results appear on screen. The app stores test history, making it easy to track battery degradation across multiple vehicles over time. For a fleet manager who checks 20 vehicles a week, the app-based history is more useful than printed slips. For a tech-forward mechanic, the wireless operation means no cable trailing across the engine bay.
vs KW210: KW210 has its own screen — simpler, no phone needed. BK100 requires a phone but adds history logging and is wireless. Choose based on whether app-based operation appeals to you. Note: BK100 only goes up to 16V — not suitable for 24V trucks.
Tell Arjun your vehicle and situation — he'll give you a straight answer, not generic advice.
