Digital multi-battery tester: Precise battery tester for batteries, button cells & block batteries. Universal battery tester for household & workshop

A must, especially when traveling: Is the capacity of the battery still sufficient? This is a question that is not only relevant to your photographic equipment. After all, the batteries in flashlights are often exhausted at the wrong time. This multi-battery tester therefore shows you the charge status and battery voltage digitally. This means you know exactly whether your rechargeable batteries are still powerful enough or whether you should carry a replacement in your hiking rucksack.

Works without batteries: The multi-battery tester itself does not require a battery. This is because the power of the battery to be tested is used for a brief moment to check rechargeable batteries and button cells. The robust little battery tester is therefore always ready for use and can be conveniently carried in your jacket pocket or in the glove compartment of your car.

Almost universal: With this multi-battery tester, you can test a wide variety of energy sources. The most common battery types (type AAA, AA, C, D), but also button cells (with 1.2 V / 1.5 V / 3.0 V) or 9 V block batteries can be tested. This means that battery-operated toys and small electrical appliances are always ready for use. At the same time, the environment benefits from this device, because never again will a battery be disposed of too early.
