Clarke C12BT 12V Digital Battery Tester review

A battery tester might not seem, on face value at least, the most vital addition to your home workshop or garage tool collection, but with bikes commonly experiencing battery issues when stored over winter, a well-rated example at a good price is almost a ‘must have’. 

This 12V digital battery tester from Clarke, as available through Machine Mart scores on both counts, gaining almost universal 5/5 reviews on Machine Mart’s own website and also currently costing just £31.19. 

The C12BT, to give it its correct model name, is designed specifically to be easy to use for the home mechanic and is also suitable for both cars and bikes. 

All you have to do is attach the two crocodile clips to the correct battery terminals of your machine, leaving the battery in-situ as you do so. Once done, the battery’s voltage, charging power and battery power are all then displayed on the unit’s easy-to-read LCD screen. 

That’s it, easy-peasy, lemon squeezy… 

The Clarke C12BT is also sturdily built with a rugged, grippy, plastic case, weighs just 0.23kg (with packaging), is available both in store and online through Machine Mart’s website, is suitable for all 12V batteries and, in the interests of safety, also benefits from reverse connection and overcurrent protection, so that even ham-fisted users can use it safely. 

Nor do you just have to take our word for it, satisfied buyers have also posted glowing reviews on Machine Mart’s website, such as, here, from Ian: 

“A good little tester. I doubted it at first but took my car to a garage and their equipment agreed with it so all is good.” 

And also from Mike: “Excellent, small, compact, and easy to use.”
