AG13 LR44 AG10 CR2032 2025 2016 PP3 6LR61 Battery capacity tester
1, Applicable for most batteries selling in supermarket, either primary or secondary, that include 1.5V/1.2V/3V/9V/12V.
1.5V batteries: D/C/AA/AAA/AAAA.
1.5V button cells: from AG0 to AG13.
3V batteries: CR series, CR2032-CR2025 and etc.
9V batteries: PP3/6LR61.
12V batteries: 23A; 27A.
2, Three LEDs to indicate battery status. For better understand, you can further divide each light into 10 degrees. That is from 0.1 to 1.0, depends on light intensity.
3, Three metal contacts on top to be connected to battery cathode(positive), probe to anode(negative).
4, Advantages: there is a small load designed to inside circuit, that can examine real power of tested battery. Voltage read from a multi-meter can be sometimes deceitful. That is high-voltage, but few charges(electricity) inside. This phenomena can be metaphorized by a man's strength. Tall and big are usually considered with strength, but not all the cases. To distinguish, we need to give a load to test. If he shoulders well, then proves to be good. If not, just seems powerful, inside is weak.
5, Unit size: 55*50*26mm.
6, Power supply: AG13/LR44*3 pieces( included ).
How to use:
1, Take out probe hidden in back slot.
2, Put battery anode(positive) to top metal contact. Left for 3V; middle for 1.5V; right for 9V and 12V.
3, Connect probe to battery cathode(negative).
4, Read LED to check battery condition.
5,Power supply: AG13/LR44*3 pieces.
