Checking batteries and rechargeable batteries. Anyone who uses batteries and rechargeable batteries is regularly confronted with the problem of their state of charge. It's annoying when you realize that the energy packs are not fully charged when you're out and about.

Versatile and clear, the Voltcraft BT-12DIG battery and rechargeable battery tester provides a clear overview: all common formats and types, from button cells to 9 V blocks, from Ni-MH/Cd to LiFePO4 rechargeable batteries can be checked for their state of charge in measuring ranges between 1.2 and 12 V. Even hearing aid, digital, and disposable batteries can be tested to protect against unpleasant surprises.
