It even fits neatly into the handy storage case, so you can take your batteries and charger with you on the go more easily.

Lights tell you the status of each battery in the charger, and it sits snuggly against power sockets without taking up too much space. The charger itself can charge between one and four AA or AAA batteries (or a mix of both) at any one time an advantage over some chargers which only charge in pairs. They're also designed to operate just as well at temperatures as low as four degrees Fahrenheit, making them great for cold climate use. The Eneloop Pro batteries don't have as many charge cycles as standard Eneloops, but they do have an extra 25% capacity, making them last significantly longer depending on the device they're powering. If you need a mix of long-life AA and AAA rechargeable batteries and could use a high-powered charger too, the Panasonic Eneloop pro charger kit has everything you need. They are now rarely used and have mostly been replaced by metal-hydride based batteries.Panasonic eneloop pro High Capacity Power Pack, 8AA, 2AAA, with"Advanced" Individual Battery Charger and Plastic Storage Case Buy From Amazon 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). The batteries have a lithium anode and iron disulphide cathode with a lithium salt as the electrolyte. Plus, theyre backed by a 10-year storage warranty. This non-rechargeable AAA uses a lithium/iron disulphide chemistry. Duracell AAA batteries deliver long-lasting power, which can result in less frequent battery replacements. They tend to have higher energy densities and capacities (850–1,200 mAh) and last longer than zinc chloride batteries. This slight difference in chemistry goes a long way in improving the capacity of alkaline batteries for the same nominal voltage (1.5 V). 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.
