hello everyone and welcome back once again today I'm going to demonstrate for you a battery tester here that I picked up on Amazon it's the bt 168 battery tester it does sells nine volt 1.5 volt triple a double-a does the 1.5 volt like I mentioned 9 volts or like I mentioned here and the cells and all the other batteries in here this cost less than six dollars Canadian on Amazon and I'm going to do a test today to see if this is actually something that can be reliable enough to test batteries so as you see here I have a variety of batteries here I have a couple have a I would consider it cheap Walmart battery great value and that is lightly used I think this is a recharged a used rechargeable battery but it is fully charged again I have a deep battery that's that came out of the radio it is moderately used but it should still be in good condition this is a lightly used 9-volt battery th
