How to Choose Rechargeable AA Batteries
More electronics require batteries than arguably ever before, but most batteries are finite sources of power that can become costly to replace again and again. Lithium and alkaline batteries are widely available as non-rechargeable options, but lithium is the most common with respect to rechargeable battery types. Instead of replacing batteries throughout the lifetime of the product, rechargeable lithium-ion choices can make the process of restoring power more convenient and economic.
What are the advantages of rechargeable Li-ion batteries?
One benefit of rechargeable batteries is their ability to be easily recharged, rather than having to be replaced when theyre empty.
- A rechargeable Li-ion battery is better for the environment than one that is disposed of quickly. Most can still release harmful chemicals and metals, but rechargeable batteries are easily recyclable.
- Lithium batteries can store more energy and last longer than other types do. NiCD (or nickel cadmium) products have a long life but offer low voltage. Ni-MH (or nickel-metal hydride) products can be higher voltage, but they also require more frequent charging. Li-ion options, on the other hand, are wise choices for high-draw applications like power tools.
- Lithium is an abundant resource, meaning that common battery sizes like AA are widely available.
What else should I consider when looking?
Multiple factors can help you to decide if Li-ion batteries are fit for a certain situation.
- The upfront expenditure for the batteries and a charger may seem high, but the lifetime value is often worth it if they will be used often.
- Batteries can lose their capacity with each recharge. When the ions move, they can change the electrodes physical structure, and these moving ions can also form a rock salt that diminishes capacity. Self-discharge, or loss of stored energy over time, is not as common in this type as others, making them fit for long-term use.
- Travelers using these in their devices may face trouble when flying. The batteries may be restricted to carry-on luggage only, but the safety of Li-ion options is still adequate.
What features do Kentli rechargeable AA batteries have?
Kentli products are widely available and include features that can make them effective choices for those requiring rechargeable batteries.
- These batteries are often sold with the charger included. USB charging is compatible with charging ports on computers or wall adapters, though it is commonly recommended that only the manufacturers original charger be used with its brand.
- Li-ion and lithium-iron options are available. Both are lithium-based and offer similar characteristics.
- Capacity can range from 600 to 3000 mAh (or 900 to 4500 mWh) depending on how many batteries are used together at once. One battery will be on the low end, with the entire set being on the high end, and sets range from two to as many as 16 or more individual pieces.
