Li-FeS 2 or Lithium Iron Disulfide is a type of non-rechargeable AA lithium battery featuring a typical voltage of 1.5 V during high drain applications, but also up to 1.8 V maximum open-circuit voltage. NiOOH batteries have a very similar capacity to standard alkaline batteries, but they can be drained using stronger currents and are often used in high drain devices like cameras and similar. NiOOH or Nickel Oxy-Hydroxide battery is a variety of alkaline battery where nickel oxyhydroxide is added to the manganese dioxide and graphite for the cathode leading to the 1.5 V typical voltage during high drain use and 1.7 V maximum voltage. Unless otherwise labeled, an alkaline battery is a primary, non-rechargeable battery. Often, they are labeled as RAM (Rechargeable Alkaline Manganese) batteries. Note: specially designed alkaline batteries can be recharged numerous times, but these are not standard alkaline batteries. When compared with Zinc Carbon batteries, the alkaline batteries have a higher capacity (hence higher energy density) and longer shelf-life, with practically the same voltage. They are based upon the reaction between zinc metal and manganese dioxide, they feature 1.5 V nominal voltage and capacity generally in the 1800 - 2700 mAh range. Zinc Carbon AA batteries are an older type of batteries, featuring a nominal voltage of 1.5 V and a typical capacity of 600 - 1600 mAh.Īctual capacity depends on the intended use of the battery (low drain, high drain) and the battery design.ĭue to the slightly lower capacity, Zinc Carbon batteries are being replaced with Alkaline batteries.Īlkaline AA batteries are practically standard AA batteries. Primary, non-rechargeable AA batteries include Zinc Carbon, Alkaline, Li-FeS2, and NiOOH batteries. The capacity of AA batteries also depends on the battery chemistry and is expressed in milliamp-hours (mAh) - capacity ranges from 500 mAh to 3300+ mAh, which is a huge difference.įortunately, the most common battery types are Alkaline (primary, non-rechargeable) and Nickel Metal Hydride (NiMH, secondary, rechargeable) batteries, but lithium AA batteries are coming on strongly.
1.5V: Zinc-Carbon, Alkaline, NiOOH, and some AA lithium batteries with the built-in DC-DC converters, The voltage of AA batteries depends on the battery chemistry and is expressed in volts (V): As one can see in the table, AA batteries differ in chemistry, capacity, voltage, and other features, and "the best of all", as time goes by, new battery types are introduced.
