![]() 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. Simply charging it does not undue this basic chemical change.Comparison of AA battery chemistry Comparison of AA battery chemistries The reason the lifespan has shorten is because of the chemical reaction converting the chemicals that make up the cell as the battery drains. Although an alkaline battery may read “good” at 1.6 volts, this reading on a LiFeS2 battery indicates the product has been discharged. Any battery with an OCV <1.70 (after it has been allowed to recover) is completely discharged. In fact, you "measuring it" at 1.6V means its DEAD:Ī “good” battery will generally have an Open Circuit Voltage (OCV) >1.74 volts. If you want to recharge lithium batteries, get standard lithium secondary cells. If they could be recharged and life expanded, they would have found a way, considering how many billions they have in funds. To be honest, if they could be recharged, Energizer would market them like that. Can you physically recharge them? As you noticed, yes, but it's not a good idea. Lithium Primary batteries are not meant to be recharge.
