Top Customer Reviews
According to data sheet published by Energizer, the capacity of the Lithium AA cell (L91) is 3000mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the Energizer E91 AA) is rated as 2800mAh, but only at a very light load of 25mA. At a heavy load of 1000mA (typical for a digital camera or flash unit), its capacity drops to below 1000mAh. This number gets even worse at low temperature. At zero degree C and 1000mA load, the L91 can provide about seven times more energy compared to the E91. This is where the marketing claim of "Last up to 7 times longer" comes from.
When used in a digital camera at room temperature of 25 degree C, the L91 is more likely to last 3-4 times longer than alkaline. This is enough to justify its price, which is also around 3-4 times higher than alkaline. However, in low-drain applications (such as smoke detector, wireless mouse or remote control) alkaline cells will last just as long at a fraction of the cost.
The L91 also contains much higher energy when compared to an ordinary rechargeable NiMH cell such as the Energizer NH15-2500.Read more ›
Note: Amazon has moved two of my previous reviews (one for Energizer Lithium AA 4-pack, one for 8-pack) under one page. Therefore I have to update my review to add some new information - or else I look like a fool who says the same thing twice.
=== New information follows ===
There seems to be some confusion about those Energizer Lithium AA batteries. Several people have bought those batteries under the assumption that they are rechargeable, only to be disappointed later.
Despite the name 'Lithium', those Energizer Lithium AA batteries are very different from the commonly known 'Lithium-ion' rechargeable batteries. Namely:
- They are single-use batteries (NOT rechargeable like Li-ion)
- The terminal voltage for each cell is around 1.65V (compared to around 3.7V for each Li-ion rechargeable cell)
The two types of batteries are not compatible. If your camera accepts AA cells, then you should use those Lithium AA cells and not Li-ion rechargeable battery. Alternatively, you may explore other rechargeable battery options, namely:
1. Low-self-discharge NiMH AA cells, such as Sanyo Eneloop or Sony Cycle Pre-Charged. Those have a operating voltage of 1.25V per cell, so some cameras (especially those that use only two cells) may not operate correctly on those.
2. Nickel-Zinc rechargeable such as PowerGenix AA.Read more ›
When it comes to cameras, digital cameras are the worst with battery power. When I first got my camera, the pair of double A batteries that came with it only lasted an hour. I then bought a brand new pack later, and those also were unusable within 60 minutes.
This was going to be a major problem. I bought a pack of special Olympus Lithium batteries (very expensive and hard to find at the time) which lasted, at max, two and a half weeks.
Finally, I found a pack of Energizer Lithium batteries. I stuck them in my camera and expected them to last about five days. To my surprise, this pack of four batteries lasted me a whole month of road trips and hang-outs.
These batteries are long-lasting, reliable, very light, and inexpensive. I was very satisfied with the performance of these batteries, and I hope this review helped you in your decision or search.
According to data sheet published by Energizer, the capacity of this Lithium AAA cell (L92) is 1200mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the Energizer E92) is also rated as 1200mAh, but only at a very light load of 25mA. At a heavy load of 500mA (typical for a P&S digital camera), its capacity is reduced to about one-third. The difference gets even greater at low temperature. At zero degree C and 500mA load, the L92 can provide about seven times more energy compared to the E92. This is where the marketing claim of "Last up to 7 times longer" comes from.
When used in a digital camera at room temperature of 25 degree C, the L92 is more likely to last 3-4 times longer than alkaline. This is enough to justify its price, which is also around 3-4 times higher than alkaline. However, in low-drain applications (such as smoke detector, wireless mouse or remote control) alkaline cells will last just as long at a fraction of the cost.
The L92 also contains much higher energy when compared to rechargeable NiMH cell such as the Sanyo Eneloop AAA.Read more ›
