![]() ![]() They are now rarely used and have mostly been replaced by metal-hydride based batteries. Nickel Cadmiums are the oldest among the rechargeable AAAs with a high self-discharge and high toxicity (cadmium is a dangerous heavy metal). The batteries have a nominal voltage of 1.2 V and a capacity of between 300 and 500 mAh. Nickel-cadmium AAAs use nickel oxide hydroxide and cadmium as electrodes with a potassium hydroxide electrolyte. Rechargeable AAAs are mainly lithium and nickel-based. Secondary AAA batteries are rechargeable, meaning you can use them over and over again. This means they can be used in standby devices like panic alarms. Lithium iron disulfide batteries have long lifespans some can last up to 20 years. ![]() Their capacity is usually around 1,200 mAh making them suitable for high-drain use in cameras and high power lighting. They give a similar nominal voltage (1.5 V) as the other primary cells (up to 1.8 V maximum open-circuit voltage). Energizer AAA NiMH Rechargeable Batteries (700mAh, 4 Pack) come pre-charged and ready to use directly out of the packaging. The batteries have a lithium anode and iron disulphide cathode with a lithium salt as the electrolyte. This non-rechargeable AAA uses a lithium/iron disulphide chemistry. They tend to have higher energy densities and capacities (850–1,200 mAh) and last longer than zinc chloride batteries. Superior performance in extreme temperatures from -40 to 140 degrees Fahrenheit great for use in all seasons. This slight difference in chemistry goes a long way in improving the capacity of alkaline batteries for the same nominal voltage (1.5 V).

Top Innovative Features for Energizer® Ultimate Lithium Batteries. Alkaline batteries are so-called because they use an alkaline potassium hydroxide electrolyte. But the difference lies in the electrolyte used. They both use zinc and manganese dioxide chemistry. AlkalineĪlkaline batteries have similar chemistry to zinc-carbon batteries. Plus, they get depleted faster than most other AAAs. Zinc-Carbon batteries get their electric current from the reaction between zinc and manganese dioxide. The battery uses zinc and carbon electrodes, and the electrolyte is typically made of ammonium or zinc chloride. Zinc-carbon cells have a nominal voltage of 1.5 V and a very low capacity (500–600 mAh), so they only work well for devices that don’t drain excessive current like TV remotes or clocks. Typically, non-rechargeable batteries come in four major groups depending on their chemistry. Some AAA batteries come in a single-use primary battery which you throw away when used up. ![]()
