![]() ![]() The four numbers indicate the week of manufacture. The first letter indicates the month and the second letter indicates the year. The code consists of two letters followed by four numbers. The Duracell Optimum Expiration Date Code is a way to tell how old your battery is. In fact, many of us have probably been using expired batteries without even knowing it! So what does the expiration date on a battery really mean?Īnd how can you tell if your battery is still good or not? ![]() Most people don’t realize that their batteries have expiration dates. The Duracell AAA Battery Datasheet also includes detailed information about the battery’s capacity and discharge rate. This battery is designed for long-term use, and it provides excellent performance in both high and low temperatures. If you’re looking for a durable and reliable AAA battery, the Duracell AAA Battery Datasheet is a great option. No matter what type of battery it is, the basic principle is the same: A chemical reaction creates electricity, which powers our devices. Nickel-cadmium batteries work similarly, but use nickel and cadmium instead of lithium and oxygen. Nickel-cadmium batteries are used in some cordless power tools. Lithium-ion batteries work by using a chemical reaction between lithium and oxygen to create electrical energy. Other types of batteries include lithium-ion batteries, which are often used in laptop computers. Lead-acid batteries work by using a chemical reaction between lead and sulfuric acid to create electrical energy. The most common type of battery is the lead-acid battery, which is used in cars. But what exactly is a battery?Īnd how do they work? A battery is a device that converts chemical energy into electrical energy. They power our phones, laptops, and many other devices. For example, an alkaline AAA has a capacity of about 1000 mAh, while lithium AAAs can have twice that capacity.īatteries are an essential part of modern life. The power output of a AAA battery depends on its chemistry different chemistries have different watt-hour capacities. The first dry cell batteries were developed in the late 1800s by Georges Leclanché and others, using an invention by French physicist Gaston Planté as their starting point. Dry cell batteries are so named because they do not contain liquid electrolyte, as opposed to wet cells which do contain liquid electrolyte. the international standard reference electrode (SRE). IEC 60086-3 defines a terminal voltage for a AAA of 1.2 volts ± 0.1 volt vs. ![]() A AAA battery is typically cylindrical, with a diameter of 10.5 mm and a length of 44.5 mm, although the size varies by manufacturer. The “AAA” designation comes from the International Electrotechnical Commission (IEC). ![]() How Many Milliamps is a AAA?Ī AAA battery is a type of dry cell battery. These parameters are a reference when a battery is needed, and specific qualities are required since batteries are used in all types of devices and for infinite purposes.How many mah is a 1.5 duracell aaa batteryĪ 1.5 Duracell AAA battery has 950 mAh. To compare and understand the capability of each battery, some important parameters are characteristic of each battery, also within a type of battery. Rechargeable nickel–metal hydride (NiMH) AAA batteries are heavier, they typically weigh 14–15 g (0.49–0.53 oz). The positive terminal has a maximum diameter of 3.8 mm (0.15 in) the flat negative terminal has a minimum diameter of 4.3 mm (0.17 in).Īlkaline AAA batteries weigh around 11.5 grams (0.41 oz), while primary lithium AAA batteries weigh about 7.6 g (0.27 oz). AAA batteries are common in portable electronic devices.Īn AAA battery is a single cell that measures 10.5 mm (0.41 in) in diameter and 44.5 mm (1.75 in) in length, including the positive terminal button, which is a minimum 0.8 mm (0.031 in). An AAA battery is one of the most common types of single-cell cylindrical batteries. ![]()
