leagend BA640 Colour-Screen Battery Tester Announced for Workshops

leagend has launched leagend BA640, a colour-screen battery tester tailored for independent garages and mobile technicians. The unit is aimed at delivering fast, highly accurate diagnostics for everyday workshop workflows, with clear on-screen readouts that make results easier to interpret during busy service bays.

leagend BA640 supports common 6V, 12V and 24V workshop needs and focuses on the measurements technicians use most when assessing a battery and its associated systems. Its compact handheld form factor and intuitive controls make it suitable for quick checks or detailed tests during servicing.

Key features of leagend BA640 include:

  • Colour display for clear readings — high-contrast screen reduces misreads in dim workshop conditions.
  • Multi-voltage support — works with 6V, 12V and 24V lead-acid batteries used across cars, vans and light commercial vehicles.
  • Comprehensive test suite — measures voltage, internal resistance, CCA and provides state of health (SOH) and state of charge (SOC) indicators.
  • Charging & cranking system checks — enables follow-up tests on alternator and starter performance without swapping kit.
  • Fast, workshop-calibrated accuracy — driven by leagend’s proprietary testing algorithm to deliver repeatable, trustworthy results technicians can act on.
