A battery has one or more cells. These cells convert chemical energy to electrical energy, and they are suitable for powering electrical devices. Batteries are suitable for use at home because they are easy to use and they offer quick power. There are different battery sizes. This variable size is to create batteries that suit the electrical current requirement of several devices. Battery sizes include AA, AAA, 9V, C, D, etc.
AA batteries are the most popular battery size. They are suitable for thermometers, cordless phones, clocks, etc. Next to AA batteries, AAA batteries are the second most popular batteries. AAA batteries generate less energy due to their smaller size. The batteries are suitable for devices that do not require a lot of energy. These devices include clocks, remote controls, timers, etc. The best AAA batteries include Energizer AAA batteries, Duracell AAA batteries, etc.
C batteries are heavy-duty, and they are suitable for toys, radios, and flashlights. These batteries are also ideal for devices that require safe and reliable power, such as restroom flush sensors. The best C size batteries include Duracell Coppertop batteries, ACDelco batteries, etc. Furthermore, D batteries deliver power for an extended period. The batteries are suitable for large flashlights, soap dispensers, and stereos. The best D batteries include EBL D size batteries, Rayovac D batteries, etc.
9V batteries have a rectangular shape, and they are ideal for devices that require high voltage and power. This battery is suitable for devices such as infrared thermometers, battery-powered alarms, and electronic scales. The best 9V batteries include Amazon Basics 9 Volt alkaline batteries, Energizer Max 9V batteries, etc.
There are different types of batteries; rechargeable and non-rechargeable. Non-rechargeable batteries are also known as primary batteries. These batteries are only suitable for single use. Types of non-rechargeable batteries include alkaline and coin cell batteries. Alkaline batteries have alkaline electrolytes. These types of batteries have a long battery and shelf life. They are ideal for powering portable devices, and they have a nominal voltage of 1.5 Volts. Alkaline batteries are a bit pricey, but they have low leakage and a low self-discharge rate. Some of the best AA alkaline batteries include Amazon Basics AA Alkaline Batteries and Duracell general purpose alkaline battery.
On the other hand, coin cell batteries have an alkaline composition and lithium or silver oxide chemicals. These batteries are lightweight, have a long shelf life, and are the longest-lasting batteries. Coin cell batteries are expensive, but they have a high performance, and they are suitable for high-drain devices. The Energizer Ultimate Lithium battery is an example.
Rechargeable batteries are secondary batteries because they are reusable. These batteries are pretty expensive, but they are worth the price in the long run. Rechargeable AA batteries can be Ni-Cd or Ni-MH batteries. Ni-Cd batteries have a nickel and cadmium composition. The batteries have a low discharge rate ad they have a nominal voltage of 1.2 Volts. The batteries are easy to recharge. Charging the battery frequently prevents the growth of crystals on the battery plate.
Ni-MH batteries are more environmentally safe than Ni-Cd batteries. Although Ni-MH batteries have a lower nominal voltage (1.2 Volts) than alkaline batteries, they can replace them. Ni-MH batteries are suitable for household appliances. However, they have a high self-discharge rate. Some of the best rechargeable AA batteries include Panasonic Eneloop rechargeable batteries, energizer rechargeable batteries, etc.
Factors to consider when purchasing batteries include the manufacturer, device, and cost. Top battery manufacturers include Duracell, Energizer, Rayovac, etc., batteries from top brands are pretty expensive but high-performance batteries. Another factor to consider is the device. Lithium batteries are ideal for high-drain devices such as digital cameras, smart devices, and wireless devices. Nevertheless, Alkaline batteries are cheaper than lithium batteries. They are suitable for high-drain and low-drain devices such as clocks, smoke alarms, remote controls, etc.
Cost is another essential factor. Rechargeable batteries are cost-effective in the long run because they are reusable. However, bulk buying batteries also saves costs.
