Great Use for camping I was looking for a battery that we could use for camping that would last for the time we would be out camping. Sometime for weeks on end. They did just what I was looking for and the price was fair. December 15, 2011
Best for outside in michigan winters The Ultimate Lithium are the best batteries i have ever used outside in my game cameras in the harsh Michigan winters. Never had a batterie work in the cold like these do. December 15, 2011
Used in a trail camera These batteries have been used for about six months, in a trail camera. In all kinds of temps from summer heat to winter below freezing. They are being used outdoors in a trail camera, and still show a full charge. A great product, and I have recommended them to friends. December 15, 2011
They last forever having a good deal of electronic stuff i use many batteries, mostly AA and the energizer fits my needs, long lasting and dependable. December 15, 2011
Ultimate Lithium I used these in my digital camera and they are still going strong after shooting hundreds of pix at a wedding and an entire two week vacation. Normal good batteries last maybe a hundred shots or so, but these seem endless! December 15, 2011
Lasts A Long Time I have found these batteries to give me far better service in the long run than rechargeables. I know that I will get close to a thousand pictures with each set; however, I cant rely on rechargeables to give me a long life after recharging. Eventually they die. Rechargeables also do not retain life after charging. With current technology, these are just the better way to go. December 15, 2011
This product lasts a very long time! I use this product in my insulin pump. I need a long lasting battery that continually works, and this is the best there is! I can usually go 8-10 weeks between having to change the battery, which is wonderful for something that is being used all day long, each and every day. December 15, 2011
Wouldn't consider buying any other battery I found myself once too often in a situation with my digital camera ready to take a once in a life time picture, and the battery was dead. I can't tell you how upsetting that was, I tried the Energizer Lithium and have not looked back, it may be a bit more pricey but it is worth it. December 15, 2011

Exhausted on Digital Camera but OK for

When ultimate lithium AA batteries show out of charge on my Pentax digital SLR camera, they still show as 'good' on my battery tester and work in a flashlight. Why is this?

Answer: 
A flat battery has a high internal resistance. It can still work at low current, for a device that doesn't take a lot of whack. It is like having a resistor connected between the device and the battery. A radio can often run on flat batteries - I used to collect them for this purpose. Reason - a radio uses a few milliamps and a digital camera is a television camera, it takes a few amps. So the digital camera would cause a flat battery to drop the voltage down to nothing, the radio wouldn't.

Answer: 
Thank you for this great question, I would be happy to assist you. Digital camera is very powerful and can drain a battery down very quick, depending on how many features or options you use. The open circuit voltage of a lithium battery can be very misleading. The condition (remaining capacity) of a lithium type battery cannot be determined with a voltmeter; the 1.5 volt reading does not indicate a good or bad lithium battery. Most battery testers are not much better since they are calibrated for alkaline battery chemistry. The flashlight might be working because the battery might still be strong enough for that device.

Thank you for taking the time to contact Energizer.

Answer: 
Thank you for this great question, I would be happy to assist you. Our Ultimate Lithium batteries actually have a 15yr shelf life, and our Advanced Lithium have a 10yr shelf life. If you are using these batteries in a high drain device (which they are designed for) they should last a bit longer then our Alkaline. If you don’t use them and are stored properly, you should get some decent service out of them. Just keep an eye on the use by date.

Answer: 
Ultimate Lithium batteries are not rechargeable. Lithium batteries work best in high drain devices like gaming systems, music players and digital cameras. You may be thinking of lithium ion, a rechargeable battery type. Ultimate Lithium and Advanced Lithium batteries should be disposed of properly when they are fully used.

Did you improve the actual capacity in the new ULs, or was the improvement achieved by flatter discharge curves? If the former, what's the difference in capacity in mAh between the old and new ones, measured at 0.1 A discharge rate?

Answer: 
3100 mAh from the data sheet. These batteries are much more effective than AA alkalines (2900 mAh) at high current drains (> 200 mA) and low temperatures(<5F). Yet at low drain rates and room temps they are not much longer lasting and certainly not cost effective. Hence, they should be purchased only if the drain rates are high or the temps are very cold. Then you will save a bundle and not have to change baterries as often.

Answer: 
Thank you for your great question! The Ultimate Lithium batteries may work very well in your flashlight. We suggest checking with the manufacturer of the light to see what they suggest to use for batteries as they have probably done extensive testing on the best battery to use in their product. Hope this helps. Any additional questions, let us know here or give us a call at 1.800.383.7323.

Why are these batteries not rechargeable?

I have never heard of lithium ion batteries not being rechargeable, why is this the case? Is it due to the fact there is no protecting circuit in the battery which makes it cheaper to manufacture?

Thank you for this great question, I would be happy to assist you. In sense you are correct, Lithium ION batteries ARE rechargeable batteries. However, our AA/AAA and 9v Lithium batteries are Lithium IRON, so there is a different chemical make up on the two batteries. I do apologize for the confusion.

Answer: 
Thank you for this great question, I would be happy to assist you. Regarding our E2 vs the Ultimate and Advanced, there is no difference. When Energizer came out with the Lithium battery the packaging read E2, this was just a marketing design (e-square). Over time the packaging changed over and it was no longer part of the package.
