Excellent Professional Battery Tester
The FOXWELL BT705 Car Battery Tester has been a fantastic purchase and completely solved a problem I was having diagnosing battery and charging issues. I was struggling to determine whether my car’s slow starts were due to the battery or alternator, and this tester pinpointed the issue straight away. It’s very easy to use – just connect the clamps and follow the on-screen instructions on the clear 2.8-inch LCD display. It gives quick, accurate readings of battery health, cranking performance, and charging voltage. I really like that it works on both 12V and 24V systems, so it’s ideal for not just cars but also motorcycles, trucks, and SUVs. The build quality feels solid and professional, and the results are consistent and reliable. It’s now my go-to tool for checking any battery before replacing it unnecessarily. Highly recommended for anyone – professional or DIY – who wants a dependable, accurate, and easy-to-use battery tester that actually gets to the root of electrical problems.

Excellent bit of kit
I had been having electrical problems with my car, all sorts of codes and dash lights poping up, sensors failnig and the like, I had chacked my battery with a digital multi meter and it showed as ok, so I couldn't understand what was going on, A lot of forums talked about how modern cars are very dependant on thebattery as a major part of the electrical and electronic system and how even a few volts of a drop can cause all kinds of problems, So I bit the bullet and bought this. Plugged it in let it do it's thing and it came back to tell me my battery was a dud. Bought a new battery and hey presto all my codes lights and issues were gone. Very easy to use and 100% reliable
