Sealey AK414 battery hydrometer – tube type tester
If you’re regularly tinkering with cars, caravans or anything running a lead-acid battery, the Sealey AK414 battery hydrometer is just the bit of kit you need to keep things ticking along nicely. This clever tester lets you quickly check the health of 6V, 12V and 24V batteries, so you can spot problems before they leave you stranded. Whether you’re a pro in the garage or just like to keep your own motor in top nick, you’ll find it dead easy to use – just pop it in and see what’s what.
What sets this hydrometer apart is the built-in thermometer – not something you see on every tester. That means it gives spot-on readings whatever the weather, so you’re not left guessing when the temperature drops. The tube design keeps things straightforward, and the clear markings make it a doddle to get an accurate reading in seconds. Plus, thanks to its compact size, you can chuck it in your toolbox or glove compartment without any faff.
You don’t have to be a battery expert to get the hang of it, either. Just draw up some fluid, check the float, and you’ll know straight away if your battery’s up to scratch or if it’s time for a bit of TLC. Perfect for keeping on top of regular maintenance – or for those times when your car’s playing silly beggars and you want to rule out the battery.
- Works a treat on 6V, 12V and 24V lead-acid batteries, so it’s handy for everything from small kit to big motors
- The built-in thermometer takes the guesswork out of testing, giving you reliable results whatever the temperature
- Tube design makes it quick and mess-free, even if you’ve only got one hand free under the bonnet
- Dead easy to use and read, even if you’re not a seasoned mechanic
- Helps you spot dodgy cells early, so you can save yourself the hassle (and the cost) of a flat battery
- Small enough to stash in your kit without taking up precious space
Tip: After each use, just give it a rinse with clean water to keep it in tip-top condition for next time. It’s a small bit of effort that keeps your readings bang on.
