As you might know, having a dead battery in the middle of a snowstorm is one of the worst experiences you can ever go through. This year one of the coolest Black Friday deals available is designed to prevent that from ever happening.

The Schumacher BT-100 100 amp Battery Load Tester is available on Amazon for a discounted price of just $25.95, compared to its base price of $58.30.

The device is designed for everyday use on 6V and 12V batteries, and can test load, check battery condition, starter motor draw and provide a detailed charging system diagnosis.

The load tester is just 2.7 pounds, and its dimensions are 15 x 7 x 4 inches, according to the Amazon listing. It is listed in the top 10 Home Improvement devices on Amazon and has a 4.5 out of 5 star average rating, so you know when you purchase one of these bad boys you're getting a good product.

Its shock-resistant meter is housed in a strong steel case with a durable baked enamel finish, according to the Schumacher site. A rubber insulated carry handle was added to the device as well for your safety.

The BT-100 also comes with a top-mounted rocker switch and super-grip battery clamps to make it easy to use no matter how experienced you are with cars.

Why we want it

The product is very easy and convenient to use, and great to have in the garage, whether you want to check a battery in a car, boat or a mower. It saves time removing batteries to take to a shop for testing and no battery is needed for the tester.
