This battery tester will test almost any battery that you come across. Some batteries will test good on a volt meter, but when you actually use them are dead. This meter puts the battery under load, getting a much more accurate reading of remaining capacity.

ZTS also makes a Mini version of this tester that tests the five most common styles of batteries, I chose to go with the larger version that test thirteen different styles of batteries.

Check it out on Amazon (If you click on any Amazon links on my website they might give me some money, which is neat)
