Tools and Hardware Reviews of Sinometer BT558 Self-powered Battery Tester
Customer Review: I like this little Battery Tester.
Summary: 5 Stars
I bought this battery tester in Sept'08 from Amazon.
I like it so far.
- The small size is nice. I keep it in the same storage box as my batteries.
- The design is nice. I like how the testing arm is part of the protective case until you use it.
- The usability is good. Easy to use. I trained my 6 year old son how to use it and now he periodically he tests and gets rid of all the depleted batteries.
My Overall rating: 5 out of 5 stars. Good quality and usability for the price. Helps to ensure my battery supply has all the bad batteries weeded out from it.
I hope you find my review helpful.

Summary: 4 Stars
We go through a lot of batteries. This allows me to test them accurately before I put the old ones in the recycling bag.Customer Review: Inaccurate as it does not test under load
Summary: 1 Stars
The problem with this battery tester is that it only checks for voltage remaining in a battery. Even a 90% used battery can show nearly full rated voltage. It is only when a load is placed on the battery that a true assessment is possible.
For example, a dead alkaline battery and a fully charged rechargable battery (NiMH full charge = 1.2 volts) both read the same low (yellow).
Look for one of the more expensive units that tests under load.
Customer Review: Inaccurate reading if not exactly placed
Summary: 2 Stars
Pro: tests many sizes of dry cell batteries. Inexpensive. Can give accurate reading if you correctly position the battery.
Con: Tester contacts have to be exactly placed on the battery and it may take two or three tries to be sure. For each reading, the needle swings back and forth so you have to be patient and wait for it to stop moving.
