How We Chose the Best Rechargeable Batteries

In making selections for our list of the best rechargeable batteries, we considered a variety of criteria. Among the most important is that rechargeable batteries need to provide ample power, extending the time between recharging. With that in mind, we chose AA batteries with at least a 2,000-mAh rating.

One should be able to recharge a rechargeable battery hundreds of times before it will no longer hold a charge, so we stuck with models with a long lifespan. Since batteries often spend a significant time in storage before they are needed, we also favored those rechargeable batteries that could retain the majority of their charge while sitting in a drawer or closet for a year or more. Finally, we considered price. A rechargeable battery can help mitigate AA and AAA battery replacement cost, so we chose those that offered tangible savings over disposable batteries.

Our Top Picks

The following list includes some of the best rechargeable batteries. They are among the most popular and widely used for a variety of electronics because these rechargeable batteries are high quality and priced competitively. Many brands with excellent options for AA sizes offer some of the best rechargeable AAA batteries, too.

What to Consider When Choosing the Best Rechargeable Batteries

You’re likely familiar with the range of battery sizes available, as a number of gadgets still require batteries. Battery nomenclature—how they are named and organized—is complex, but the letters on batteries also indicate their size. (For example, AA means 50.5 mm by 14.5 mm.) But the letters aren’t the only labels to look for when shopping for rechargeable replacements. Before switching to rechargeable batteries, pay attention to these additional four features.

Chemistry

There are four main types of rechargeable batteries for home use that differ in terms of the chemicals that produce their charge: nickel cadmium (NiCD or NiCaD), alkaline, lithium-ion, and nickel metal hydride (NiMH). Each has its strengths and is useful for different purposes.

If picking up a couple of varieties for different uses around the house, be careful not to confuse them. Never mix batteries of different chemistries in the same device.

  • NiCD batteries are often used in power tools.
  • Alkaline batteries are the best batteries for regularly used, low- to mid-drain electronics, like digital clocks and remote controls.
  • Lithium-ion batteries are designed for smart technologies (phones and laptops) and solar panels as they can withstand extreme temperatures.
  • NiMH rechargeable batteries are the most common variety for household uses. They have a high energy capacity (see below) and are excellent for high-energy electronics like flashlights, toys, and digital cameras.

Capacity

A battery’s energy capacity describes its electric power over time and is measured in milliamp hours (mAh). The higher the mAh, the longer a battery will last. Disposable NiMH AA batteries have an mAh range between 1,200 to 1,900. In comparison, rechargeable NiMH AA batteries have an mAh range between 1,700 and 2,500. Do not mix batteries of different capacities within the same device, or else one will drain faster than another and negatively affect performance.

There is also a difference in capacity with AAA versus AA batteries. While most AAA batteries will have around 900 mAh, most AA batteries have around a 2,500 mAh capacity. The longest-lasting rechargeable batteries have capacities as high as 2,800 mAh.

Charge Time

The amount of time it takes for a battery to charge depends on its capacity (mAh). Fast-charging NiMH AA batteries can take 3 to 4 hours to charge fully. When purchasing new rechargeable batteries, they should come charged and ready to use.

Another important factor is the length of time a battery can hold a charge. Quality rechargeable batteries can hold 75 to 90 percent of their total charge for up to a year in storage.

Lifespan

A rechargeable battery’s lifespan is measured in the number of recharges it can cycle through. The best rechargeables on the market boast between 500 and 2,000 recharges per battery.

Be aware that NiMH batteries offer fewer recharges than some of the other types of batteries. However, they also need to be recharged less often, so they still typically last longer.

Charger

Rechargeable batteries use a charger to refresh them once they’ve been drained. These chargers range in capacity from as few as four batteries to as many as 40. They also vary in sophistication. Most models have indicator lights that change color when the batteries are fully recharged. More advanced chargers provide more detailed info, allowing the user to see exactly how much juice is remaining in a battery.

A quality charger will also switch to a trickle mode when the battery nears a full charge to prevent damaging the battery and ensure it charges fully. More advanced chargers allow the user to set different charge rates, refresh batteries by discharging and recharging them, and test the battery capacity.

Tips for Using Rechargeable Batteries

There are several ways to get the most out of your rechargeable batteries while extending their lifespan. First and foremost, don’t be chintzy on the charger. A “smart” charger will charge your batteries without undercharging them or overcharging them. Avoid using super-fast chargers, which can overheat batteries, decreasing their lifespan from 500 charges to fewer than 100.

Don’t leave your batteries in the charger for more than 24 hours to avoid damaging them. When a battery in a device is drained, remove it from the device immediately or make sure the device is off. A device that continues to drain a discharged battery could reverse its polarity, causing it to stop working. Be patient with new rechargeable batteries, as it can take three to five charge cycles for them to reach their full capacity.

  • Use a quality charger
  • Do not use a fast charger
  • Avoid leaving batteries in a charger for more than 24 hours
  • Be patient with new batteries

FAQs 

If you’re wondering how many times you can recharge a rechargeable battery or what the longest-lasting rechargeable is, then read on for answers to these and other questions about rechargeable batteries.

Q: Do rechargeable batteries last as long as nonrechargeable batteries?

Rechargeable batteries have a shorter shelf life than standard nonrechargeable batteries. A rechargeable battery will typically last between 3 and 5 years, while a lithium nonrechargeable battery has a typical shelf life of 10 to 12 years. An alkaline nonrechargeable battery will last 5 to 10 years. Of course, once a nonrechargeable battery is used, it cannot be recharged.

Q: What are some disadvantages of rechargeable batteries?

There are some disadvantages with rechargeable batteries. Some rechargeable batteries produce less voltage than disposable batteries, which can affect performance. Rechargeable batteries also have a higher up-front cost than disposable batteries. Rechargeable battery performance also becomes unpredictable as they age and hold less and less charge.

Q: Does it matter which charger I use for rechargeable batteries?

You can use any brand to charge a rechargeable battery; however, the type of charger must match the battery. For example, a NiMH battery will only work with an NiMH charger. To maximize the lifespan of the battery and ensure you’re getting a full charge, it’s also a good idea to use a smart charger.

Q: How long can you leave rechargeable batteries on the charger?

Most battery chargers automatically set themselves to trickle once the batteries reach a full charge; however, it’s a good idea to avoid leaving the batteries in the charger for more than 24 hours to prevent damage to them that can shorten their lifespan.

Q: Which rechargeable batteries last the longest?

With a 2,700-mAh capacity, Powerex PRO rechargeable AA batteries are among the longest-lasting options we could find.
