Kingbolen BM520 car battery tester
If you’re sick of guessing whether your car battery’s on its last legs, the Kingbolen BM520 is a cracking bit of kit to have in your glovebox or garage. This clever tester takes all the mystery out of battery health checks, letting you see exactly what’s going on with a clear, colour readout – none of that squinting at old-school dials. Whether you’ve got a car, van, SUV, motorbike, or even a boat or ATV, the BM520 handles the lot, testing 6V, 12V, and even 24V batteries from a titchy 2Ah all the way up to 220Ah.
What’s really handy is how simple it is to use. Just clip it onto your battery – no faffing about with which way round the leads go, as it’s got reversible access that stops you getting it wrong. It runs a series of tests, including starting and charging checks, and gives you the results in plain English so you’ll know straight away whether your battery’s fighting fit or ready for the tip.
You can use the BM520 on all sorts of batteries, including AGM, GEL, EFB and the usual lead-acid ones. For anyone with a stash of different vehicles or a small fleet, that’s seriously useful. Even for smaller batteries – think motorcycles, scooters or lawnmowers – there’s an ultra-low detection mode so nothing gets left out. And, if you like to keep tabs on things, you can save and replay up to five test records, so you can spot if your battery’s starting to go downhill over time.
Updates are a doddle too – just plug it into your computer or even some Android phones, and you’ll get the latest firmware for free. With a robust build and a solid two-year warranty, you really can’t go wrong.
