Review on Tenergy 1.5V C Alkaline LR14 Battery - High Performance C Non-Rechargeable Batteries for Clocks, Remotes, Toys & Electronic Devices - Replacement C Cell Batteries 12-Pack by Sara Reyes

The first 4 I picked didn't seem to work, the next 4 worked perfectly so there was probably 1 battery in the first 4 that was dead or dead , but since I have the emergency toy 4, it is difficult to test one battery at a time, so far the second set of 4 batteries in the toy have lasted since Christmas and plenty of playtime. I need to see how long the packaging lasts and decide if I need to buy these again or rechargeable versions.
