Standard batteries are the kind most people picture when they think of disposable battery power. They're found in everything from thermometers to staffing pagers.

Rechargeable battery
These have a much higher energy density than single-use batteries and are great for high-drain devices. They can also handle many charge-discharge cycles.

AA
The AA battery is one of the most common types of batteries used in household electronic devices. These batteries use dry cell technology to power small electrical devices that consume low amounts of energy, such as remote controls and clocks. AA batteries are also known as standard batteries, and they can be found in many electronics stores. These batteries are available in both rechargeable and non-rechargeable varieties.

The type of battery that a device requires depends on its power requirements. For example, a flashlight may require a higher voltage than a clock. The device's owner's manual should specify which size of battery is required. Generally, high-drain devices such as digital cameras require AA batteries, while lower-powered items such as remote controls and clocks can be powered by AAA batteries.

When choosing a battery for a specific device, the type of chemistry should be taken into consideration. Different chemistries offer different capacities, voltages and discharge rates. Zinc-carbon and alkaline AA batteries are non-rechargeable, while NiMH, NiZn and lithium batteries are rechargeable. Lithium batteries also have a much lower self-discharge rate than other chemistry types.

Regardless of the battery chemistry, all AA batteries are cylindrical and have a diameter and length of 14.5 mm x 50.5 mm. They have a nominal voltage of 1.5 V, which is based on the zinc-carbon battery's chemistry. The AA battery's capacity is measured in milliampere hours, with the exact figure being dependent on the battery chemistry and test conditions.

Although most individuals understand how batteries operate, confusion can still arise when selecting the correct battery size for an individual device. AA and AAA batteries are the most commonly used types of replacement battery in households, but it is important to know which type is required for each device. Typically, high-drain devices like digital cameras will require AA or AAA batteries, while low-drain items such as TV remotes can be powered by a single AA battery.

Whether a battery is rechargeable or not, it should be stored properly. This can reduce the risk of leaks and corrosion and extend its life. When storing a battery, it is recommended that it be kept in a cool, dry place away from direct sunlight and other heat sources. In addition, the battery should be placed in a plastic case to protect it from environmental damage. If a battery is accidentally dropped, it should be picked up carefully to avoid damaging the internal components. Additionally, the battery should be discarded once its charge is depleted. This will help prevent environmental pollution and will ensure that the battery's cells are not damaged. In addition to preserving the environment, this practice will save money in the long run, as replacing a battery is more expensive than simply recycling it. The cost of a new battery can vary depending on the brand, type and retailer, but it is possible to find an affordable price with some comparison shopping. This is especially true for online retailers, which can often offer cheaper prices than traditional brick-and-mortar stores.
