Battery Use/Storage: We want to take a moment to review proper battery use and storage. When you receive your batteries, please keep them stored in the original plastic tray that they were delivered in. Doing this ensures that there is no way any 2 batteries will be touching each other, and in effect draining power before use. Storing them in their original packaging keeps them all together and prevents any single batteries to be misplaced! **DO NOT STORE YOUR BATTERIES IN A BAG, OR ANY OTHER CONTAINER. THIS WILL RENDER YOUR BATTERIES DEAD IN A MATTER OF MINUTES** All batteries are checked for full charge before being sent out. Our policy ensures that you are receiving a functioning set of batteries.
