Energizer - Advanced Lithium AA Batteries (4-Pack)

I just love those lithium batteries they last so long.

I have a black and decker energy monitor that attaches to my power meter. It tells me how much power my house uses in real time. With regular batteries it quits in the hot summer and cold of winter. Using lithium cells it works all year on one set no matter the temp.

I use it in powerful tool. works great. prefer lithium ones.

The batteries on my digital camera need to be replaced often. Very frustrating when I'm in the midst of trying to take pictures and then I get the "low battery" signal. Checked online for reviews and these batteries seemed to have good results. So far these batteries are doing good, but I've only used them for about a month, so don't know if I'm going to run into the same issue.

My son is a diabetic and is on an insulin pump it requires a fully charged battery or it will reject it have used those "copper " batteries went through 7 before getting one acceptable in fact when they send a pump them with theENERGIZER .so I up grated to the Advanced the regular lasted about 3 weeks these last so long about 7 to 8 love these WELL WORTH THE MONEY!

My daughter ran an experiment with these batteries comparing them to the Energizer Ultimate. It turns out that although they did not last as long as the Ultimate batteries, these only lasted slightly less time than the ultimate on average. The Ultimates ran for 14 hours 15 minutes, while these lasted about 13 hours 15 on average.

If you need AA batteries for your digital camera go with these. They last a lot longer than your standard AA battery. When using two batteries in one device and the device appears to be dead, do a voltage check on both batteries. What I've found is that most of the time only one battery has lost its charge but the other is still holding 1.5 volts or more.

I use these as back-ups for my rechargable batteries when I travel. I don't have to worry about them losing a charge like the others. They stay charged until I use them. Eventually I throw them out and don't have to carry them around. They have come in handy many times when I take a lot of pictures before I can recharge the other batteries.
