Ansmann Universal LCD Battery Checker with Capacity Test
This premium battery checking unit will test almost all types of batteries. It will measure the cell's capacity on standard AA/AAA/C/D/9V/12V batteries, button cells and lithium batteries such as those used in digital cameras.
The LCD display indicates the level of capacity in terms of a percentage so you'll be able to monitor the life of your batteries. Cell capacity is shown in the following increments: 100-90%, 80-60%, 50-30%, 20-10% and 0%. There is also a "self test" function to test the unit's own 9V battery.
Retailers, offer your customers a free battery checking service with this industrial grade checker.
