Kingbolen BM550 car battery tester
If you’ve ever found yourself stuck with a flat battery (usually at the worst possible moment), you’ll know what a lifesaver a decent battery tester can be. The Kingbolen BM550 is exactly the bit of kit you’ll want stashed in your glovebox or garage. Designed to work with 6V, 12V, and 24V batteries, it’s spot-on for cars, vans, trucks and even the odd motorhome – basically, if it’s got a battery, this thing can handle it.
What really sets the BM550 apart is its versatility. You can use it on almost any standard lead-acid battery, including the newer AGM and EFB types found in start-stop engines – so you’re covered whether you drive a classic or something bang up to date. It’ll test batteries from a tiny 2Ah all the way up to a beefy 220Ah, with cold cranking amps (CCA) ratings from 100 to 2000. The big, clear display makes it a doddle to read your results – no squinting or guesswork required.
Using it couldn’t be easier: just hook it up, follow the prompts, and in seconds you’ll know if your battery’s fighting fit or in need of some TLC. It’s tough enough to cope with regular use in all sorts of weather, so whether you’re a weekend tinkerer or a pro mechanic, you’ll get plenty of mileage out of it. The whole unit is compact and light, making it a breeze to chuck in the boot or keep handy in your toolkit.
- This tester works with 6V, 12V, and 24V batteries, so it’s ideal for everything from runabouts to work vans and lorries.
- It’s compatible with most battery types you’ll find in UK vehicles – lead-acid, AGM (flat and spiral), GEL and EFB (just steer clear of deep cycle batteries).
- You can check batteries as small as 2Ah, right up to the big lads at 220Ah, with CCA ratings from 100 to 2000 – so it really covers all the bases.

- It’s built to last, with a rugged design that shrugs off knocks and cold mornings in the garage.
- Handy for everything from routine servicing to tracking down those annoying intermittent electrical problems.
- Keeping an eye on your battery health helps avoid the hassle and expense of unexpected breakdowns.
- To keep your tester working tip-top, just wipe it down after use and store it somewhere dry – easy as that.
