Battery Tester BTW 6V/12V
High-performance and reliable.
The BTW 6V /12V is a high-tech connected battery tester. It tests both the battery and the alternator, and its “screenless” design makes it very economical. Designed to run tests directly on your phone or tablet, its dedicated application is very easy to use and enables you to manage a fleet of vehicles (cars, motorbikes, etc.) efficiently.
The BTW 6 V / 12 V is a cutting-edge, high-performance battery tester designed for 6V and 12V lead-acid batteries, including SLA, VRLA, GEL, AGM FLAT PLATE, AGM SPIRAL, open FLA, and START/STOP (EFB/AGM) types. With a “screenless” design, this economical tester sends test results directly to a mobile device via a dedicated app, making it ideal for efficient fleet battery management.
