Solid mid-capacity batteries
In This Article
Verdict
A reliable set of mid-range batteries, the Duracell Rechargeable AAA 750mAh perform consistently. The main problem is that the competition is tough, with cheaper, longer-lasting or higher-capacity batteries available.

Introduction
Just about the biggest name in batteries, Duracell has impressed with itsRechargeable AAbatteries. The Duracell Rechargeable AAA 750mAh aren’t quite as good: mid-level capacity and a relatively low number of charge cycles mean that the competition performs better.
Design and Charges
Longevity is important for rechargeable batteries, but the Duracell Rechargeable AAA 750mAh offer a relatively low number of charge cycles. All of the official imagery shows that these batteries can last for 100 charges, which sounds poor. Head to the official site, and it says that the batteries will last for three years or 400 recharges. Even so, that isn’t great – even theAmazon Basics Rechargeable AAA 800mAhlast for 1000 recharges.
As is the case with most other modern rechargeable batteries, the Duracell Rechargeable AAA 750mAh will retain up to 80% of their charge after 12 months. That’s useful, as you can charge and store them, on standby for when you want to use them. Plus, if you use them in low-drain devices such as remote controls, you won’t lose a lot of power each day.
Performance
To see how well these batteries performed, I ran them through a set of standard tests using an Ansmann Energy XC3000 battery tester. First, I started by measuring voltage, which should be a minimum of 1.2V; the result of 1.24V is just within.
Next, I measured capacity using a high-drain test (600mA +/-20% with a cut-off voltage of 0.94V). Here, I found that the initial capacity was 732mAh, which is just below the rated capacity. Most batteries that I test score higher than the rating printed on the side of the battery itself.
To measure longevity, I charged and discharged the batteries 50 times, taking a capacity reading every 10 cycles. As you can see from the graph below, the results were consistently around 700mAh – bar the final cycle, which topped out at 800mAh.

Should you buy it?
If you need a set of reliable batteries for items such as remote controls, for example, then these fit the bill.
If you need a greater number of charging cycles or more capacity, then there are better options available.
Final Thoughts
The Duracell Rechargeable AAA 750mAh are good-enough batteries, particularly for low-drain items such as remote controls. The main problem is that the competition is better. If you want longevity, the Eneloop AAA are superior, while theAnsmann Micro AAA 1100mAhoffer more capacity.
How we test
Unlike other sites, we test every rechargeable battery we review thoroughly over an extended period of time. We use standard tests to compare features properly. We’ll always tell you what we find. We never, ever, accept money to review a product.
Find out more about how we test in ourethics policy.
We use an Ansmann Energy XC 3000 to drain batteries, so that we can test capacity in mAh. After the first run, we charge and discharge 50 times, measuring the capacity every ten runs.
We measure the initial voltage of the batteries, checking that the starting voltage is at least 1.2V.
