Best Rechargeable Batteries

Why is it important to find the best rechargeable batteries? Mostly because, like getting a more efficient dishwasher, it is an incredibly green option.

The most obvious reason to make the switch to rechargeable batteries is because it means less waste. Instead of throwing away batteries when they are depleted, you recharge them. In fact, many of these batteries can be reused thousands of times before they no longer hold a charge. This means that you could get years of use out of them. Compare that to the weeks or months that you would get from a typical alkaline battery.

Along with less waste, you’ll also enjoy greater convenience. In the same way that a high-tech microwave can make your life easier, the best rechargeable batteries are designed to streamline your life. Whenever you need new batteries, simply remove the fully charged ones from the charger and pop the depleted ones into the charger. Fresh batteries are always within your reach.

Which Rechargeable Battery is the Best?

In recent years, there has been an explosion in options for rechargeable batteries. Some of these are more reliable and powerful than others. It’s also worth noting that there are significant differences in price. While some rechargeable batteries are downright cheap, others feel like a major expense. Is paying more really worth it?

In the following reviews, we’ve taken a closer look at eight of the most popular rechargeable batteries on the market today. Through rigorous testing, we uncovered the performance metrics for each model, and we also examined how much value you get for your money with each choice.

Read on to discover which of these recommended rechargeable batteries make the most sense for your requirements and budget.

Panasonic Eneloop


Rating: 4.6 out of 5 stars on Amazon
Price: $11.54 (Discounted. Regularly $14.99)

Panasonic EneloopEneloop is a well-known name in the field of rechargeable batteries. This particular model is noted for its incredible 2,100 charge cycles. That’s more than any other rechargeable battery on the market today.

The most recent generation of these batteries hasn’t been on the market long enough to really test this longevity in the real world, but Eneloop has a respectable pedigree. It’s easy enough to believe that these batteries can live up to the hype.

Pros

  • An amazing 2,100 charge cycles
  • Maintains 70 percent charge even after not being used for 10 years

Cons

  • Expensive
  • Expected a longer runtime considering the expense and hype

These batteries have an overall score of 4.6 out of five stars on Amazon. More than 9,800 customers have left their reviews so far, and 83 percent of these are five-star reviews. Fans of these top-selling rechargeable batteries say that these are a trustworthy choice, especially if you ensure that you’re buying from the latest, fourth-generation models. These all begin their model numbers with a “BK.” Accordingly, you’ll be getting the batteries that are rated for 2,100 charge cycles.

With their capacity to be recharged so many times, these are the ideal choice for someone who uses a lot of batteries and needs to frequently recharge. If this describes you, then these batteries may be worth the price.

Features

  • Composition: NiMH
  • mAh rating: 2,000
  • Number of recharge cycles: 2,100
  • Number of days battery holds a charge: Maintains 70 percent charge for 10 years when not in use
  • Hours of use per charge: Eight

An eight-pack of AA batteries will run you about $20 on Amazon. If they truly are able to be recharged more than 20 times, this is definitely a spectacular deal.

Energizer Recharge Universal


Rating: 4 out of 5 stars on Amazon
Price: $9.99

Energizer Recharge UniversalWith the ability to successfully recharge more than 1,000 times, these Energizer Recharge Universal batteries are an impressive entry in the marketplace. Making them even more attractive is that they are made up to four percent of recycled batteries.

If you’re looking for the best rechargeable batteries because you believe in leading a greener lifestyle, then these are the perfect choice.

Pros

  • Dependable batteries that last for years
  • Inexpensive when compared with options of similar quality

Cons

  • May need to periodically use a recharge conditioner
  • Some users report having to charge before first use

Overall, Amazon users give these batteries a four-star rating, with 343 customer reviews so far. Reviews suggest that these batteries can last for years, with some customers commenting that they had their previous set of batteries for 12 to 15 years. However, others note that they need to use a recharge conditioner on the batteries after about two dozen uses. These devices appear to make the Energizer batteries work as good as new.

Additionally, although the packaging says that these batteries arrive with a charge and ready to go, some users report that this did not reflect their experience. Be prepared to charge these batteries before their first use, if necessary.

Features

  • Composition: NiMH
  • mAh rating: 2,000
  • Number of recharge cycles: 1,000
  • Number of days battery holds a charge: 365
  • Hours of use per charge: Between five-and-a-half and eight

With an eight-pack of AA batteries costing less than $20 on Amazon and the possibility of a lifetime that goes beyond a decade, these Energizer batteries are an undoubted bargain. Be prepared with a recharge conditioner to get the full use out of each of these batteries.

Panasonic Eneloop Pro


Rating: 4.5 out of 5 stars on Amazon
Price: $20.24 (Discounted. Regularly $24.99)

Panasonic Eneloop ProWith excellent performance, the Panasonic Eneloop Pro almost deserves the top spot in this review. However, the price for these batteries is undoubtedly steep, and they can only be recharged 500 times.

That doesn’t compare very favorably with the Energizers or even the fourth-generation Panasonic Eneloops. Nonetheless, these are high-capacity batteries with a higher mAh rating.

This means that they run longer on each charge. For the right application, this might make them the perfect choice.

Pros

  • 2,500 mAh for a longer charge
  • Can be recharged when either fully or partially discharged

Cons

  • Expensive
  • A relatively low number of charge cycles at 500

On Amazon, these batteries have garnered approximately 4.5 out of five stars. This statistic relies on more than 3,075 reviews, 81 percent of which give this product five stars. Most people are happy with the performance of the Pro product. However, some of them aren’t so sure that they are really worth the price.

Now that NiMH batteries have largely replaced the NiCd batteries with their terrible reputation for developing a “memory,” it isn’t necessary to worry about destroying a battery’s capacity by charging it up when it’s not fully depleted. Perhaps it makes more sense to go with a battery that can be recharged more times. Still, these batteries definitely do perform.

Features

  • Composition: NiMH
  • mAh rating: 2,500
  • Number of recharge cycles: 500
  • Number of days battery holds a charge: Maintains 85 percent charge for 1 year when not in use
  • Hours of use per charge: Up to 25

While it’s true that the Pro version of these highly rated rechargeable batteries may only be recharged about 500 times, it’s worth noting that the life cycle of a single charge may be up to 25 hours. That is a far longer-lasting charge than many of the items on this list.

If you prefer to recharge batteries less often, these may be perfect for you. With a price tag of more than $30 for an eight-pack of AA batteries, it pays to be certain that this is what you want.

AmazonBasics Rechargeable Batteries


Rating: 4.1 out of 5 stars on Amazon
Price:ย 
$16.49

On Amazon, this choice has garnered more than 2,000 reviews and has a rating of 4.1 out of five stars. Seventy percent of these reviews are five-star reviews. Fans say that the mAh rating is comparable to that offered by Eneloop, yet the price is far less. As one reviewer says, these are “brand name quality at affordable pricing.”

Features

  • mAh rating: 1,900-2,000
  • Number of recharge cycles: 1,000

AmazonBasics High-Capacity


Rating:ย 4.1 out of 5 stars on Amazon
Price:ย $17.49 (Discounted. Regularly $18.99)

AmazonBasics High CapacityWith these AmazonBasics High-Capacity Rechargeable Batteries, you get outstanding performance, though the Eneloop high-capacity option will give you more hours of runtime.

Still, these are priced at about $17 for an eight pack, which is a good bargain.

Pros

  • Almost 10 hours of runtime on a charge
  • Affordable when compared to other high-capacity options

Cons

  • Runtime isn’t particularly long for a high-capacity battery
  • Disappointing longevity

With 4.1 out of five stars and nearly 6,000 reviews on Amazon, it’s safe to say that plenty of people have an opinion about this product.

Sixty-eight percent of the reviews are five-star reviews, with many people saying that they get great performance from these batteries while also appreciating the price. Critics say that these products aren’t living up to the advertised 500 recharge cycles.

Features

  • Composition: NiMH
  • mAh rating: 2,400
  • Number of recharge cycles: 500
  • Number of days battery holds a charge: 80 percent after one year of non-use
  • Hours of use per charge: 9.5

With over nine hours of average runtime, these batteries are solid performers. However, you get more runtime out of Eneloop high-capacity batteries, which may make them worth the additional cost.

RayHom Rechargeable Batteries


Rating: 4.2 out of 5 stars on Amazon
Price:
$13.99

RayHom Rechargeable Batteries

If you’re in a bind and need a really inexpensive rechargeable battery option, then give these a try.

They’ll work well enough initially to get you through a rough patch.

Pros

  • Cheap
  • Reliable performance early in the life cycle

Cons

  • mAh rating may be misleading
  • Not the best longevity

An eight-pack of AA RayHom Rechargeable Batteries gets 4.2 out of 5 stars on Amazon. This only accounts for 41 customer reviews, 63 percent of which give this product five stars.

Priced at less than $15, these batteries certainly are a bargain. However, some reviewers who tested the mAh rating say that these batteries didn’t test anywhere near the 2,800 that is boasted on the packaging. Keep this in mind when making a purchase decision.

Features

  • Composition: NiMH
  • mAh rating: 2,800
  • Number of recharge cycles: 1,200
  • Number of days battery holds a charge: Holds 80 percent of charge after three years of non-use
  • Hours of use per charge: 5.5 hours

RayHom Rechargeable Batteries have a bargain price, but you may need to buy them too frequently to really make them a good value.

EBL Rechargeable Batteries


Rating: 4.2 out of 5 stars on Amazon
Price: $15.99 (Discounted. Regularly $14.99)

EBL Rechargeable Batteries

These EBL Rechargeable Batteries are among some of the most affordable in this review.

This will certainly mean that they appeal to some people. Additionally, their stated mAh of 2,800 is certainly impressive, but some tests suggest that this number may be inaccurate.

Pros

  • Affordable
  • When these batteries work, they perform well

Cons

  • Several reports of people receiving a few duds in each pack
  • Doubtful claims of the number of recharge cycles

A 4.2 out of five-star rating on Amazon certainly isn’t bad. A full 70 percent of the more than 1,100 reviews give this product five stars. However, many people report that at least some of the batteries in the pack they received simply wouldn’t hold a charge. The good news is that the company seems determined to provide excellent service. Most of these customers received replacement batteries at no cost.

Features

  • Composition: NiMH
  • mAh rating: 2,300
  • Number of recharge cycles: 1,200
  • Number of days battery holds a charge: Maintains 75 percent charge after three years of non-use
  • Hours of use per charge: Up to seven

It’s certainly nice to see a truly affordable entry on this list, and many reviewers say that they have had good performance with these batteries. If you’re on a tight budget, you might give these a try.

Final Thoughts


When it comes to buying the best rechargeable batteries, there is always a balancing act between price and performance. Some people are willing to pay top dollar if it means excellent performance and not having to buy batteries so frequently.

Others are more concerned about their budget. This review shows that there are options out there that strike a reasonable balance between these two metrics.

 

FAQs


Q: Which rechargeable battery lasts the longest?

A: It is virtually impossible to answer this question definitively since it will depend upon a number of factors. In the above review, the Pro version of the Eneloop Rechargeable Batteries came out ahead of the pack with a possible 25 hours of runtime. It is vital to note that this does not necessarily mean that you will get 25 hours of use out of every charge of each battery.

Perhaps the factor that makes the most difference is the device in which the batteries are used. Some drain batteries faster than others. Nonetheless, if you choose high-capacity rechargeable batteries, you will get a longer runtime than you will with ordinary rechargeable batteries.

Q: What is the difference between alkaline and lithium batteries?

A: Lithium batteries are largely replacing the more traditional alkaline batteries in the marketplace. This is because they are lighter, have a longer charge and a higher voltage range. Of course, this improved performance comes at a price. Lithium batteries are always more expensive than alkaline batteries. The reason behind the difference between the two batteries is their composition. Lithium metal is used in lithium batteries while alkaline batteries rely on manganese oxide and zinc. As lithium batteries become more dominant in the marketplace, alkaline batteries may become a thing of the past.

Q: What kind of batteries is not allowed on planes?

A: One of the few restrictions that the TSA places on batteries is that they be rated at fewer than 100-watt hours. The case of exploding smartphones made people fear bringing lithium-ion batteries onto planes. However, the TSA does not limit your ability to carry these onboard, especially when they are in devices.

If you are packing spare batteries, you may need to make certain that they are packed separately, such as in individual plastic bags, and that their contacts are covered with electrical tape.

Lithium batteries with more than 100-watt hours may be brought on board in carry-on bags. However, they are not allowed in checked bags. It generally is necessary to obtain airline approval for bringing these batteries on board in carry-on bags.

The TSA limits passengers to bringing just two of these batteries on the plane. Moreover, there is a possibility that an individual TSA official may make the decision not to allow the passenger to go through the checkpoint with these batteries.
