But today's rechargeables will hold charges for a year or more — Rayovac and Energizer even advertise their batteries will stay charged for five years. Rayovac's standard alkaline batteries are also modestly priced at 72 cents each, so you'll start saving money after three batteries.
Low-power rechargeable AA batteries cost just $1 each, while beefy 2,450 mAh batteries are only $1.75 each. And in our tests, the true capacities were all too close to make a difference in real-world use. Rechargeable AA and AAA batteries almost always last longer, cost less, and reduce waste compared with single-use batteries.

But temper your enthusiasm, because they also have a low 1,350 mAh capacity, so you can expect a shorter battery life. Some battery brands perform better than others, but some off-brand batteries are made on the same manufacturing lines as their brand-name counterparts. But temper your enthusiasm, because they also have a low 1,350 mAh capacity, so you can expect a shorter battery life.
This is due to the fact that once it is fully charged, it doesn’t lose its capacity as quickly as others.

In most cases, one rechargeable battery costs about what four or five standard batteries cost. Along with the Energizer Recharge Universal AAAs—which have a capacity rating of 700 mAh and, based on our testing, an average capacity of 712 mAh—these two brands provided a hair more capacity than rated for. It doesn’t hurt that each of the components is a favorite of ours—the charger is our top pick, and, while not the absolute best, Panasonic’s AA and AAA batteries were both among the top performers in our testing—so you aren’t making a major trade-off on quality.As the writer of this guide, I spent four hours researching and 120 hours testing AA and AAA rechargeable batteries. Rayovac AA Rechargeable Batteries Wondering which is the best battery in a Rayovac vs. Duracell battle of affordable brands? For example, Costco's Kirkland-brand batteries are made by Duracell, and By comparison, the Panasonic Eneloop AAAs have a rated capacity of 800 mAh and had an average capacity of 720 mAh in our testing. Thus, the worst batteries in terms of performance were ClearCell, ExtraPower, icellTech, Sony, Rayovac and Renata (average of 250 hours), the intermediate group comprised Energizer (264 hours), PowerOne (300 hours), and Panasonic (312 hours), and best performance Duracell (372 hours). We tested the capacity out of the box by charging and discharging the batteries on a charger that displayed the capacity, then averaged the results.
After draining and recharging a battery from each of our top brands 50 times, we found that all three brands had retained a lot of their capacity. On paper, the EBL AAAs were a clear favorite, but we have some external concerns about reliability that we explain in the In our real-world tests, the AmazonBasics AAAs kept a flameless candle flickering for two days and nights (48 hours) and kept a remote-control car racing for a full workday (eight hours).
Brand matters, though not necessarily in the way you think. 4-Rayovac = 6h12m. Standard Duracell CopperTop AA batteries are more modestly priced at 89 cents each, leaving them in the middle of the road pricewise. Duracell's rechargeable batteries have nearly as much capacity as the Panasonic Eneloop — but they're also more expensive than the 2,000 mAh Eneloops and get middling reviews after real-world testing. Panasonic Eneloop batteries have received good marks from several reviewers, including Even after including the cost of Also, electronics that constantly draw low amounts of power—such as some wall clocks, headlamps, or bike lights—work better with disposable batteries. Typically, these devices are universal, so you can charge any NiMH battery — including those on this list — in any NiMH charger.
They're neither the best nor the worst rechargeable batteries on the market, and if you find them at a good price they may not be a bad buy. Also …
You can also expect any rechargeable batteries you buy to be pre-charged and work right out of the package.
Their performance is on par with the much more expensive Panasonic Eneloop — possibly because they're Eneloops by a different name.
Save on a range of items for the home, including decor, home furnishings, kitchen items, and more. Today's rechargeable batteries are typically nickel-metal hydride, or NiMH, and they can have as much — or even more — power than traditional alkaline batteries.
But even though traditional AA batteries can cost as little as 30 cents each, that adds up if you go through a lot of them. Tired of throwing away money on batteries that don't seem to last?
