Ultratool 12V car battery and relay tester
If you’re fed up with chasing electrical gremlins or want to save yourself a trip to the garage, the Ultratool 12V car battery and relay tester is just the bit of kit you need. Whether you’re a seasoned mechanic or just handy around the driveway, this nifty little tester makes sorting out relay problems a total doddle.
Rather than blindly swapping out fuses and relays hoping for the best, this tester gives you a clear yes-or-no answer in seconds. Just hook it up to any standard 12V car battery, pop in your relay, and let the LEDs do the talking – green means your relay’s spot-on, red means it’s time for a replacement. It works with both 4 and 5-pin relays, so it’s got most vehicles covered without any faff.
What makes this one really handy is its size. It’ll slip into your glovebox or toolbag, ready for action whether you’re sorting a stubborn starter in the garage or diagnosing dodgy electrics at the roadside. It’s dead easy to use, too – no degree in rocket science needed, just a quick check and you’re off.
This tester doesn’t just save you time and hassle – it can help keep you out of sticky breakdown situations by catching relay faults before they leave you stranded. Pair it with your multimeter and you’ll have most electrical niggles sorted in no time.

- LED lights show clearly if your relay’s working, so you don’t waste time scratching your head.
