How Long Do Aa Batteries Last When In Use. YMMV-- Best regards Han. Factors that determine shelf life is the quality of the manufacturing process the chemical composition etc.
These batteries do not last nearly as long as Alkaline Nimh or Lithium batteries. Once the batteries dip below 135 volts they appear to be dead even though they still. Better batteries will show a later expiration date.
From October 2010 to April 2011 production Rayovac Ultra Pro alkaline batteries have increased performance on ANSI tests by 5 on average in AA 3 on average in AAA.
Heat facilitates the chemical reaction car batteries use to generate electricity but it also increases the rate of battery degradation. In cooler northern climates a battery may last five years or longer but in hot southern locales a car battery will typically last approximately three years. Ive used AA alkaline batteries that have sat in a drawer for two. These batteries do not last nearly as long as Alkaline Nimh or Lithium batteries.
