Introduced 1911, but added to ANSI standard in 1959 Sometimes used in pen flashlights, laser pointers, powered styluses, calculators, fishing lures. ![]() ( July 2011) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.

See Battery chemistry for a list of other electrochemical systems. The following tables give the common battery chemistry types for the current common sizes of batteries. For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size. The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. The same physically interchangeable cell size or battery size may have widely different characteristics physical interchangeability is not the sole factor in substituting a battery. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. I’ve listed the price for the pack of eight (around 68p per battery), as it’s a good compromise between pack size and price.3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries Bigger packs are generally better value (although not always), with prices per battery dropping to around 55p. For a set of four, expect to pay around 73p a battery. Latest dealsĭuracell Plus batteries are available in a wide range of unit sizes. That’s a decent overall capacity and these batteries should do well in low-drain applications, such as in remote controlsĪs with most alkaline batteries, Duracell says that these have a 10-year shelf life, so you can buy in bulk and not worry about them discharging while not in use. I measured the Duracell Plus AAA at 146mAh, giving me a total capacity of 560mAh. I give batteries a few hours to cool down, and then re-run the same test to measure any residual capacity. That’s alright, but is a way behind the Amazon Basics Alkaline AAA batteries. That’s just behind the nominal 1.5V that you’d expect from alkaline batteries however, as voltage drops quite rapidly with alkaline batteries, this minor variation doesn’t matter.Īfter the initial drain, I measured a capacity of 414mAh. I started by measuring the initial voltage of the batteries, which I bought from Amazon, at 1.49V. Its drainage test uses a high load of 600mA (+/-20%) with a cut-off voltage of 0.94V. In short, batteries deliver more power under lighter loads less under high drain conditions. ![]() As with all batteries, the total capacity of the batteries depends on temperature, load and the cut-off voltage (voltage drops as the batteries are drained). Other batteries perform better in the high drain testĭuracell provides a detailed specification sheet for its AAA Plus batteries.That’s a little disappointing considering how well the Duracell Plus AA batteries did in my tests. There’s also the high price to consider, with these batteries costing a lot more than much of the competition. Overall tested capacity in my tests was good, although the batteries didn’t do as well as some of its competitors in the initial high-drain test. The default choice for anyone that wants long-lasting batteries, Duracell has built a good name for itself. Picture a set of AAA batteries in your head, and the Duracell Plus AAA are probably the set that you’re thinking of. ![]()
