Every car battery is some amount of time away from failing, so the only thing for anyone with a car, motorcycle, truck, RV, ATV, boat, or other 12V battery-dependent vehicle can do is to make their battery’s demise as convenient as possible. A car battery tester that reveals a battery’s current state of health is the best tool to accomplish that goal, and a great one is nearly half off at Walmart right now.
The Askmuse Car Battery Tester is on sale for $20, 46% less than the $37 it’ll normally run you. It’s a simple device, a handheld unit with a few buttons and a screen attached to a pair of testing clamps, but it can save you hundreds of dollars, not to mention lots of time and hassle, if you’re able to replace a battery before it dies on you.

To use this tester, simply attach the high-quality brass alligator clamps to the battery in question and turn on the unit. It can provide an accurate test report in a few milliseconds with information including voltage, internal resistance, cold-start current, battery capacity, charging condition, cranking condition, and alternator condition along with calculations like the battery’s cold-start ability and aging level. This information can help you identify whether the battery is the problem if your car won’t start, and it can also let you know to switch it out for a new model before you get stranded in a parking lot somewhere waiting for roadside assistance.
“Works great!” wrote one shopper. “It helped me to determine that a loose wire was the cause of low voltage from the battery.” That catch saved the shopper more than enough money to justify the cost of this tester, particularly on sale as it is now.
Another shopper put it even more simply, writing that this “impressive” tester is “fast, accurate, and easy to use.”
If you’ve got a car, boat, ATV, or all of the above, the Askmuse Car Battery Tester is a great thing to have on hand. For $20, you can even afford to buy one to stash in all of your vehicles, as its compact size, easy operation, and quick results mean it’s great on the go.
