Two days ago, I saw an interesting thing from Low Yat Plaza, 2nd floor and it just costs RM9. So, I brought it. It is a battery tester. When I reached home, I started to test it out and it works. It works for AA, AAA and 9V batteries.
This battery tester is really useful because many of my old batteries which I thought low battery level are actually not until I tested them out. So, don’t straight away throw all your old batteries. Get one battery tester to test them out. They might still have good level of battery in them.
