    this is the handiest little tool for batteries. I must have 4 elec meters/testers and this one is perfect just for batteries. saved me a few bucks by testing and keeping what I thought were dead batteries.

      I bought one of these sometime ago when PJ first started advertising them. I haven’t used it that much and it became unreliable. I felt like the contact on the inside of the sliding mechanism was bad because I could move it around and it would sometimes work. I bought it one more time to give it another shot. Maybe mine was just defective.
