Our pick

Topdon BT100

Choose the Topdon BT100 for checking a 12V car battery and investigating cranking or charging-system problems.1

Why this one

  • The Topdon BT100 covers 100 to 2,000 CCA and lists flooded, AGM flat-plate, AGM spiral, GEL and EFB batteries, so it suits those common battery types within its rating range.1
  • Its cranking and charging tests let you check those parts of the starting problem alongside the battery assessment.1
  • The backlit LCD helps you read the results in a dim garage.1

Read the review

Before you buy: The Topdon BT100 has no built-in printer, so choose a printing tester if you need paper records.2

Other contenders

  • Clore Automotive BA327

    Choose the Clore Automotive BA327 for workshop paper records or broader voltage coverage: it has a built-in printer and tests 6V and 12V batteries plus 12V and 24V charging systems.58

For keeping a printed record of every test

A paper test record calls for a tester with a built-in printer.8 The Clore Automotive BA327 is the pick for this, combining its printer with a 40 to 2,000 CCA range and listed support for start-stop AGM and enhanced flooded batteries.8
