Laser 4294 battery hydrometer tester
If you’ve ever been caught out by a flat battery, you’ll know how handy it is to keep an eye on your lead-acid batteries – whether it’s your motor, your boat, or even your caravan. The Laser 4294 battery hydrometer tester is a cracking bit of kit for anyone who wants to make sure their battery’s in tip-top shape before it lets them down.
This tester makes checking your battery’s health a doddle. It measures the specific gravity of the electrolyte in your battery, which is a fancy way of telling you how charged – or knackered – it is. The floating discs inside are spot-on and dead easy to read, so you’ll know in seconds if your battery’s got enough juice or if it’s time for a recharge (or even a replacement). It’s temperature-compensated too, so you don’t need to worry about cold mornings or a bit of heat in the garage throwing off your readings.
What’s more, the Laser 4294 is built to take a bit of stick. Made from proper high-grade plastic and glass, it’s lightweight but tough enough to survive life in the toolbox. It’s compact enough to stash in the glovebox or boot, so you’re always ready in a pinch – whether you’re a professional mechanic or just like to keep your pride and joy running sweet.
- You can quickly spot a dodgy cell and sort it before it leaves you stranded on a Monday morning.
- It helps squeeze more life out of your battery, so you’re not forking out for a new one every year.
- It’s ideal for everything from cars and vans to boats and backup generators – anywhere you’ve got a lead-acid battery ticking away.
- There’s no fiddling about with complicated electronics – just a simple, reliable test in seconds.
- Give it a rinse with fresh water after use and it’ll keep giving you accurate results for yonks.
