Battery Tester - Digital

Precise watch battery tester with easy-to-read, red LED digital display and "Load"-function: this enables you to check the capacity of watch button cells 1.5V (301-399) and lithium cells 3.0V (BR/CR-series). Power supply by 9V battery.

Technical details:

Dimensions (L x W x H): 115 x 85 x 65 mm

Weight: 100 g

Instructions for use:

1. Connect the supllied 9V inside the battery compartment.

2. Using the black mini-cable, touch the minus pole of the battery and read the voltage.

3. Press the "LOAD" button at the same time and wait approximately 2-3 seconds to read the voltage again. During the test, you will receive important information about the estimated lifetime of the button cell:

a) If the voltage remains stable, this means that the battery is OK!

b) If the voltage does not remain stable or even has a tendency to fall sharply, we can assume that the life of the button cell will be short; It is recommended to replace the battery.
