Panasonic Digital Power AA Alkaline Batteries - 4 Pack

These are good batteries at a reasonable price. As I write, they are powering my wireless mouse. They also provide the power for my TV remote control, my LED flashlight, and even the remote control for my ceiling fan.

It is possible to give batteries an objective rating in milliampere-hours (mAh), an indication of how much charge they store. Unfortunately, the manufacturers rarely provide us with that information. All that I can say is that these batteries seem to work at least as well as any others.

the only real way to compare batteries would be to place 2 different brand batteries in 2 same devices & see how long they last. i didn't do that. simply these are batteries & they work. my only other way is to compare on price & at about $1. a battery here on Amazon, they're not as cheap as 50 cents a battery when on sale at CVS. other than that, good batteries.

Buy Panasonic Digital Power AA Alkaline Batteries - 4 Pack Now

These alkaline batteries have been powering my digital camera, and since first installing them, I've taken about 70 photos. Panasonic products are usually reliable, which is the case here. They cost a bit more than others, especially off brands, but do seem to last longer. I'd buy these again for my camera.

Based on test results using digital cameras published in Consumer Reports, Panasonic Digital Power batteries performed essentially the same as their nearest competitors, Eveready Gold and Rayovac. That's the good news. The problem for Panasonic, however, is that Eveready Gold AA alkaline batteries cost only half as much and Rayovac just 60% as much. While Duracell CopperTop batteries cost the same as Panasonic, they outperformed them 223 camera shots to 195. Based on either cost or performance, Eveready Gold, Rayovac, and Duracell CopperTop were found to be better buys than Panasonic Digital Power.

Want Panasonic Digital Power AA Alkaline Batteries - 4 Pack Discount?

I didn't know Panasonic made batteries! I often shop locally for batteries and have never seen Panasonic, just the typical EveryReady, Duracell, and Rayovac. I don't remember purchasing batteries from Amazon ever before although I make almost daily purchases from Amazon (316 so far in 2012, 324 in 2011, 193 in 2010, 206 in 2009...) and have never noticed them as customers also bought this. The Amazon listing says they have been available on Amazon since March 16, 2003; who knew?

I was very pleased to be offered these on the Amazon Vine program (lucky me!) and tested them to work wonderfully in every electronic device I tested them in. I really like the Panasonic name and don't recall ever having a problem with anything manufactured by Panasonic; it is a brand I trust as higher quality and lower defective rate.
