The most common consumer battery is the lithium-ion battery (the battery used in most of the consumer electronics we use on a daily basis). It is the most widely used battery type on the market because it is lightweight, rechargeable and can hold its charge for a long time.

But lithium-ion batteries come with a few setbacks — for example, they’re typically not as durable or as powerful as other types of batteries. To solve this, manufacturers are now creating a new type of lithium-ion battery designed to be much more powerful with a longer life span.

These new batteries fall under a variety of names, but they are all similar in nature: lithium-iron-phosphate, lithium-ion polymer and lithium-manganese-cobalt (to name a few).

If you’re looking for high-quality rechargeable batteries for the electronic devices you use every day, you’re in luck! We’ve put together this list of the 10 best rechargeable lithium-ion batteries of 2021.

Frequently Asked Questions (FAQ)

Which brand of rechargeable batteries is the best?

Rechargeable batteries is a huge market. There is usually a very large variety of sizes and mAh both in AA and AAA rechargeable batteries. There are also a few different types of rechargeable batteries including NiMH and lithium-ion batteries.

NiMH stands for Nickel-Metal Hydride and lithium-ion batteries stands for lithium-ion polymer. Usually, when you buy rechargeable batteries, you are getting NiMH batteries. These batteries are very stable. They lose about 5% of their charge after six months, and take about eight hours to recharge, but they are the most affordable to buy.

If you are looking for rechargeable batteries that last longer, you can consider Lithium-ion batteries. These are pricier, and take up to 15 hours to charge, but they lose less charge in time which makes them worth it.

Which rechargeable battery lasts the longest?

Type of battery: CR123 vs AA

CR123 is newer battery in comparison to AA. High tech CR123 batteries come in higher capacities (1350 mAh, etc.) while AA batteries maxes out over 2000 mAh.

However, CR123 are more powerful and expensive in comparison to AA. For some devices such as flashlights, high capacity AA batteries can give enough power. It depends on your needs on which battery you will choose. If you are planning to use AA batteries, get the highest capacity you can afford. They hold power well and are designed to last longer than other batteries.

What are the most powerful AAA rechargeable batteries?

AAA batteries are smaller than AA batteries. Typically, AAA rechargeable batteries can use up to 1000 milliamp hours (mAh) of energy, compared to AA batteries which use 1600mAh of energy.

Most of the rechargeable batteries have a 1350mAh capacity. UPG 1600mAh batteries is a powered label designed to test these batteries. It is a superb brand and has a long life.

If you are looking for something that has an even superior battery life, look into Sony and Energizer rechargeable batteries. Sony batteries, specifically those with the rating of 2500mAh, perform exceptionally well and last longer, and are thus preferred over the UPG and Energizer rechargeable batteries. Regardless, each of these brands delivers exceptional battery life and performance.

What should I look for in a rechargeable battery?

Pay attention to the milliampere-hours (mAH) rating. The higher it is the more charge the battery can store. Batteries generally have lower milliampere-hours ratings with different models, so you want to pay close attention to this when making a selection. The higher wattage means more power in a shorter time, so keep that in mind as well.

Conclusion

From the list above, we recommend that you choose from the first two models on the list, as they are the best in class.

However, if you already have an existing AC adapter, then you can choose from the fourth, fifth, or sixth models on the list. They are still considered to be the best models in their respective categories, although the fourth and fifth models on the list require you to purchase an AC adapter separately.
