Battery Load Tester 100 A

The KAIHENG tester applies a fixed 100 A load to 12 V batteries and a 50 A load to 6 V batteries. It measures voltage with ±0.2 V accuracy on a four-character LCD display. Copper alligator clips with insulated grips connect to the terminals for starter-motor simulation and charging-system checks.

For DIY battery health checks

Suits owners who want to verify 6 V or 12 V lead-acid batteries in cars, motorcycles, boats or RVs without visiting a shop. Not for users who need to test 24 V systems under load, analyse lithium chemistries, or log data over time.

Clips on, press switch, read display

A 24 cm lead lets the unit sit clear of the battery while the clips grip the posts. Hold the load switch for up to 10 seconds; the perforated housing vents heat from the internal coil. First use may produce brief odour or smoke from the protective coating — this is normal.
