12V Battery Tester

Good product - had alt issues and tested on one car and showed good indication - however on 2nd car it did not show any indication - meaning the unit was in good order - As 1st test car had new alt and batteries.Charge lights in 2nd car went off about 2500 RPM - but there was not output from alt using volt meter. with engine runningTherefore 2 sources of info led to a new alt being sourced for 2nd car. Nice handy piece of kit to have in garage to hand. For the situations like the above

Well made. Works well. Simple to use.

Basic but simple to use and informative. Worth a place in any toolbox

This tester is straightforward to use and gives a clear, instant reading. I used it on my car battery and straight away knew it was time for a replacement. Saved me breaking down at the worst time.The display is bright and easy to read, the clips are solid, and it feels durable. Handy little gadget for peace of mind before long trips.

Yep..brilliant..worked a treat in finding a fault with the battery charge so we could confirm a new alternator was required. Arrived quicklyvand very good price.

It works, & easy to use

Nothing special does what you need to do, really good price.

I couldn't be arsed to get my multimeter every time I wanted to test the battery and alternator. This done the trick in an idiot proof way, brilliant. Green light good. Red light bad. Back to my cuppa in no time. It's smaller than I thought it would be which is better to fit in tool bag. Display is clear. Battery test is a doddle. Build quality is light weight but seems durable enough with the cables and I'd say that would be the weak link if any. Obviously don't put heavy tool on top of it. Safe operation. Detected voltage no problem and put my mind at ease that my issue lay else where. Brilliant and at this price I thought why not.
