Verdict

Price is one of the biggest selling points of Amazon Basics High Capacity Rechargeable 2400mAh AA Batteries. They offer excellent value for money, especially when purchased in larger packages. In my testing, these batteries consistently delivered high capacities, but they didn’t hold as much of a charge as competing units. Also, Amazon does not provide detailed lifetime fee information.

introduction

Design and Fees

  • Batteries lose significant charge over 12 months
  • Big capacity

I’ve been a fan of previous Amazon Basics batteries, but these are the first rechargeable units I’ve tested. They come with a few more compromises over alkaline batteries; but for the right people, they might be a good choice.

Amazon is a bit coy about detailed battery specs, saying the Amazon Basics High-Capacity Rechargeable 2400mAh AA can be recharged “hundreds of times,” but without giving an actual number for charge cycles. for life.

Amazon is clearer on retention of charges: 70% after six months and only 50% after one year. If you’re looking for batteries to store longer or use in low-drain devices such as remote controls, you may prefer batteries that retain higher charge percentages, such as the Duracell Rechargeable AA 2500 mAh (80% after a year) .

Performance

  • High capacity in my tests
  • Reliable performance

To test the batteries, I use an Ansmann Energy XC3000 battery tester. First, I measure the initial voltage, which for NiMH batteries should be a minimum of 1.2V. I measured the Amazon Basics 2400mAh High Capacity Rechargeable AA at 1.4V. The voltage drops to the as the batteries are used, although for rechargeable batteries this drop is at a reduced rate.

Then I measured the initial capacity with a high-drain test (600mA +/- 20%). Here, the Amazon Basics 2400mAh High Capacity Rechargeable AA scored 2677mAh. It’s a good chunk more than face value.

Then I cycle (charge and discharge) the batteries 50 times to see if they start to lose capacity. I take measurements every 10 cycles. From the graph below, you can see that these batteries are holding up well, with little variation between cycles.

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 properly compare features. We will always tell you what we find. We never, ever accept money to review a product.

Learn more about how we test in our ethics policy.

We use an Ansmann Energy XC 3000 to drain the batteries, so we can test the mAh capacity. After the first cycle, we charge and discharge 50 times, measuring capacity every ten cycles.

We measure the initial voltage of the batteries by checking that the starting voltage is at least 1.2V.
