A Must Have 4 Every Home
Yes, this is a must have item because it is one of those things is very useful & pays for itself quickly.I have discovered after testing many batteries. that when devices that are powered by say, 4-8 AA's stop working due to low battery power.that it does not always mean that every battery is dead. sometimes 1 or more are still good. as in 75 - 100%!I just spent a half an hour or more going through a box of used batteries …. 2/3r
- It operates quickly, providing results in seconds
- The tester may not be able to test batteries while they are in use.
