Autophix BAS300 Plus 2-in-1 car battery tester & OBD2 scanner
If you’re after a proper bit of kit to keep your car running sweet, the Autophix BAS300 Plus is well worth a look. It’s a clever 2-in-1 gadget that checks your 12V battery’s health and doubles up as a full-blown OBD2 scanner. Whether you’re tinkering away at home, sorting out a mate’s motor, or working on customers’ cars in the garage, this tool helps you stay one step ahead of any gremlins under the bonnet.
Battery playing up? The BAS300 Plus takes the guesswork out of things. You can quickly run a load test, check how the battery copes when you’re turning the key, and make sure your alternator’s actually charging the thing. On top of that, when that pesky engine warning light pops up, the OBD2 side lets you read and clear fault codes, see what the sensors are picking up, and get a proper handle on what’s going on. No need to faff about with separate tools – it’s all in one handy, pocket-sized unit.
The display is spot-on: big, bright, and easy to read, even if you’re squinting under the bonnet on a grey British afternoon. And the menu’s as simple as it gets, so you don’t have to be a tech wizard to get stuck in – just plug it in and crack on. Ideal for anyone who wants to dodge costly surprises at the garage or simply likes to keep their car in tip-top nick.
- Checks the health of standard 12V lead-acid batteries from 100 to 2000 CCA, so you’ll know if yours is on its last legs before it lets you down.
- Runs a cranking test to see if your battery’s got the oomph for cold starts – handy for those frosty winter mornings.
- Assesses your alternator and charging system, meaning you can spot issues before your battery goes flat at the worst possible time.
- Works as a proper OBD2 scanner for most cars from 1996 onwards – read and clear codes, check sensor data, and keep on top of those warning lights.
- Small enough to stash in the glovebox or toolbox, so it’s always on hand when you need it.
- Super easy to use, with a high-res screen that gives you clear, no-nonsense results in seconds.
Tip: Give your battery a check every couple of months, especially before a big trip or as the seasons change. It’s a cracking way to avoid those “won’t start” moments and keep your car running like clockwork.
