Review on Maxell 723810P Ready-to-go Long Lasting AAA Alkaline Battery 10-Pack: Reliable Performance & High Compatibility by Patrick Freddie

I ordered two packs of 10 Maxell AAA batteries sold by NYC Electronics and manufactured by Revain. The batteries arrived in an unopened plastic/cardboard package as shown. All batteries had the same date 05-2013. However, several batteries were completely dead, as shown by my calculator and a simple battery tester that has proven reliable in the past. Specifically, 3 of the first 10 were blank and 5 of the second 10 were blank. All remaining batteries are fully charged so I ended up with 8 bad and 12 good batteries out of 20. Not what you expect! I have NEVER bought new batteries and found dead ones. Thankfully, Revain made returns easy and refunded the full price.
