Sunwa 1.5V/9V/Button Battery Power Level Tester

Pros: Bought this to quickly test batteries used for toys and other devices. Helps verify if a battery is completely dead. Works well on 1.5v batteries.
It is fairly well built and I didn't have any issues using it for different types of 1.5 v batteries.

Cons: Will tell you when a battery has full charge but if a battery is only half depleted, it is hard to tell as it may still be in green zone but would fail to work in a device that needs full power.

Other: Works well, helps you make good use of batteries.

Pros: If this would really work, it would be a nice device.

Cons: -It is just an indicator whether the battery is empty or not... -Do not expect to get reliable results from this device. I tested an AAA battery to use in my voice recorder. It indicated 'Good', but within an hour my recorder had stopped working due to a low battery. After testing the battery again, the battery tester still indicated that the battery was 'good' -quite big

Other: Waste of money, from my point of view.

Pros: It shows how much the battery life is on a battery, before deciding to throw them out, good build quality, it helps alot if you have a lot of remotes around the house to know which batteries are dead or good

Cons: The readings are not super accurate but it does say which ones are excellent, and bad. after a while you wont use it as often as you think you would. the coponents installed were poorly done since everything is rubing on the red panel

Other: I wouldnt recomend to buy this item, because you will end up not using it as often as you think since you could easily misplace it

Pros: It is a very useful tool for the home. When you have many batteries for toys, remote controls, etc. and do not know which are good and which already have to recycle. Good build quality. Measures virtually all formats of batteries, including batteries 9v and button type. It is advisable to have on hand when needed.

Cons: The readings are not accurate perhaps. well indicates when the battery is charged, but may discharged battery which seems to operate in a low power device.

Other: good product
