The lithium batteries compared here is lithium-iron (Li-FeS2) batteries, there does also exist lithium batteries with 3 volt, they are usual sold in other sizes (CR123, CR2), but can also be found in AA size, but cannot be used instead of ordinary AA batteries. Unloaded voltage will be around 1.8 volt. These batteries are rated with 1.5 volt and has around 3000mAh.Īccording to Energizer the battery will work down to -40☌, but with reduced capacity. Today they are very rare, because they have been replaced by alkaline batteries, that has considerable better performance.Įnergizer has a datasheet with specifications and their AA has about 2900mAh at 25mA load, but only about 1400mA at 500mA load.Īccording to Energizer the Alkaline battery will work down to -18☌, but with reduced capacity.Īlkaline batteries is also known to leak and destroy equipment, even unused cells can leak. They are rated for a 36 months self life and can be used from -10☌ to 50☌. The Varta datasheet for these batteries specifies 1000mAh when discharge at unspecified low current. These batteries are rated 1.5 volt, their actual capacity is seldom specified, because it varies with load. Some of the other names used for the AA cell size is: penlight, mingon, MN1500, M IEC uses R6 for the AA battery size and then places a letter before, depending on chemistry, the most common are: LR6=Alkaline AA, FR6=Lithium AA, HR6=NiMH AAĪNSI uses 15A for alkaline AA, 15LF for lithium AA and 1.2H2 for NiMH AA. The AA battery has been around a long time and during that time many different names has been used, both from manufacturers and from standard organizations. The standard size of AA batteries is up to 50.5 mm long (including plus pole) and 14.5 mm in diameter, this was standardized in 1947 by IEC (but the battery was in use long before that). not rechargeable, NiMH,NiZn and LiIon is rechargeable. Zinc-carbon, alkaline and Lithium are primary batteries, i.e. In this article I will look at some different AA battery chemistries: zinc-carbon, Alkaline, Lithium, NiMH, NiZn, LiIon.
