I use coppertop AAA batteries in my razor which I use every day to shve my head and face. I am going on 30 days with the same battery and it is still running strong. I love these batteries. I also use the AA in my DirecTV remote controls in my house. I used to go through batteries at least once a month. With the coppertop, you can notice the difference in the speed the guide pops up.
I was eager to try out the Duracell Rechargeable Batteries & Charger because I am one who goes through batteries like clock-work. I have a battery drawer full of all brands and types. I have tried out an Energizer Charger & "C" Batteries before so I have a comparison between the two to share. I gave Duracell a 4 out of 5 stars due to the quick charge time but small size. Duracell charger gives you a red/green light to let you know when they are finished charging. I feel they were always recharged within an hour and ready to go. However, I have only had to charge them up twice. I used the AA batteries for my Wii Remote and the AAA for my graphing calculator I use for college. Not once has my devices died due to batteries yet. However, I still go ahead and charge them back up every couple days anyway. The charge time is great and they last a long time. My only complaint is the size of the charger. It only holds enough room for 2 AA and 2 AAA batteries. Some devices annoyingly use 3 or sometimes 4 batteries. So this small charger would be best used for 4 AAA or 4 AA. Not mixing two and two. If you use both AA and AAA around your house often then I'd recommend buying TWO Duracell chargers. Compared to Energizer charger, the Duracell is amazing. Energizer's batteries dies so quickly and require charging almost every 24 hours. The charge time to fully recharge the C batteries were 3+ hours. Duracell exceeded my expectations for a rechargeable device.
Great case of batteries. They are wonderful quality that last a long time. It's great to buy this quantity and the expiration date is a few years out so they definitely will last.
