Emtech LaboratoriesHearing Aid Battery Tester Keychain

Perfect for my needs
This little battery tester is essential for me to assist my 98 year old father with his hearing aids. I never know if a battery that's laying around is new or old so I always need to test. He has his own tester but it tends to wind up in mysterious places, so I bought one to keep on my keyring so I always have one available. Perfect and low cost!
