Equivalent those batteries with the correct application for best resultsThe Energizer L91 Lithium AA room is a fantastic power source. For high-drain applications, it offers great advantages over norm alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is grave to recognize the strength of L91, and use it only in applications that give you the best results. Otherwise you'll be wasting your money. According to materials sheet published by Energizer, the capacity of the Lithium AA cell (L91) is 3000mAh. This reckon remains nearly constant with load current. In comparison, the ordinary Alkaline mobile (such as the ) is rated as 2800mAh, but only at a very light load of 25mA. At a heavy load of 1000mA (in keeping for a digital camera or flash unit), its capacity drops to below 1000mAh. This number gets even worse at low...
Lithium AA batteries are NOT the same as Lithium-ion Rechargeable
[Updated on June 8, 2011] Note: Amazon has moved two of my anterior 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 communication - or else I look like a fool who says the same thing twice. === New information follows === There seems to be some mixture about those Energizer Lithium AA batteries. Several people have bought those batteries under the assumption that they are rechargeable, only to be dissatisfied later. Despite the name 'Lithium', those Energizer Lithium AA batteries are very different from the commonly known 'Lithium-ion' rechargeable batteries. Namely: - They are cull-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 apartment) The two types of batteries are not compatible. If your camera accepts AA cells, then you...
Compare with those batteries with the correct application for best result
The Energizer L92 Lithium AAA chamber is a fantastic power source. For high-drain applications, it offers great advantages over strange alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is weighty to recognize the strength of L92, and use it only in applications that give you the best results. Otherwise you'll be wasting your money. According to materials sheet published by Energizer, the capacity of this Lithium AAA cell (L92) is 1200mAh. This tally remains nearly constant with load current. In comparison, the ordinary Alkaline mobile (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 (representative 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 millstone, the L92 can provide about seven times more energy compared to the E92. This is where the marketing claim...
