Using the proper batteries makes a huge impact on the overall performance and longevity of your device. This guide will explain the various battery sizes and kinds so you can get the most out of your device.

1. Lithium Batteries

Lithium batteries are one of the most commonly used battery types. They offer the highest energy density of any other battery cell, meaning they store more energy than other batteries, such as alkaline. Lithium batteries are only sold in AA, AAA, and 9V sizes; however, their mAh ratings exceed every other non-rechargeable battery. One AA lithium battery ranges from 2,700-3,400 mAh, and will last a long time, even under heavy use.

2. Alkaline Batteries

Alkaline batteries are among the most commonly used batteries today. They are inexpensive and can be found in nearly every retail store in the world. The biggest downsides of using alkaline batteries are their low energy density and short lifespan compared to other types of batteries. However, they are good for non-critical devices, such as remote controls and flashlights.

3. AGM Batteries

AGM batteries are becoming a popular power source, especially for solar applications. AGM stands for absorbed glass mat, and these batteries include lead and acid. They are able to store more energy than typical lead-acid batteries, and are generally more durable. These are also a good fit for long-term, off-grid power systems. Because AGM batteries are a good balance between sealed lead acid (SLA) and gel batteries, they are among the most popular batteries for solar applications.

4. Gel Batteries

Gel batteries are typically used in place of flooded lead acid or AGM batteries. They require little maintenance and have a longer lifespan than both flooded and AGM batteries. Gel batteries are not used in as many solar applications, due to their higher cost. However, they are a good fit for off-grid systems and other power systems that need a more reliable, long-lasting battery.

5. Carbon Zinc Batteries

Carbon zinc batteries are the least expensive type of battery you can purchase. They are also the least powerful and least durable of the common battery types. They are usually used for low-drain devices, such as smoke detectors and clocks.

6. Zinc-Air Batteries

Zinc-air batteries are different from every other popular battery type, because they are more of a fuel source than a power source, such as alkaline or lithium batteries. Zinc-air batteries are a good solution for devices that only need a small amount of power, such as hearing aids and watches.

7. Rechargeable Batteries

Rechargeable batteries can be used up to one thousand times in their life, making them more cost-effective than disposable batteries. However, they are more expensive at the outset than traditional batteries. Rechargeable batteries are the best choice in terms of battery life, and they are the most environmentally friendly, since they are reusable. The most rechargeable battery sizes are AA, AAA, C, and D; however, they can be found in nearly every battery size. Rechargeable batteries can be recharged using solar, wind, or AC power.

Conclusion

Batteries are incredibly important to modern technology, though they have undergone several updates since their invention. You should choose an energy source that is most friendly to your person or your project. You should also consider your power needs, the equipment you are powering, and the environment when making your choice.
