Panasonic Heavy Duty C Batteries X 12

Have to use with my ADT. In my opinion Energizer doesn't last as long as Panasonic.

You really cannot beat the price of batteries on Amazon! Even if you end up having way too many, it is still cheaper to buy the giant pack on Amazon then the smaller pack locally. Typically I just ask a neighbor or relative if they want to split a pack of batteries if I know, I’m going to have way too many extras.

these batteries are a real good value at the price

A GREAT GROUP OF BATTERIES AT A VERY GREAT PRICE11 THANK YOU SOMUCH!!!Alfred

cheap

The web page for these batteries has a misleading description, claiming these batteries are either alkaline based or carbon-zinc based, depending on what part of the description you read. I've already reported this problem, but it doesn't change the fact that I wanted to buy alkaline batteries and wound up getting old-school carbon-zinc. Yes, they're still batteries. Yes, they still make my flashlights light up. But carbon-zinc doesn't have the shelf-life of alkaline, and they don't last as long in devices. In fairness to Panasonic (who had nothing to do with the Amazon web page) there is nothing wrong with how these batteries were made, and I probably paid a reasonable amount for them. But, when I say reasonable I mean that when I buy alkaline batteries I'm able to use them all before they die because of their superior shelf-life. Whether or not what I paid for these carbon-zinc batteries was reasonable will actually depend more on how long their shelf-life turns out to be. Supposedly, carbon-zinc cells can last 5 years from what I found when I researched them. Alkaline batteries can last longer than that if they're fresh. I guess I'm going to find out just how long carbon-zinc really will last!

ran down faster so I bought rechargeable batteries

Price is reasonable and they work well. I order repeatedly. Recommend.
