Ansmann MaxE AA 2100 Evaluation: Lengthy-lasting batteries

The Ansmann MaxE AA 2100 is a superb set of batteries. Providing respectable capability, these cells can final for as much as 100 cost cycles and so they additionally discharge fairly slowly. Nevertheless, the Ansmann MaxE AA 2500 can be found for the same value, so are in all probability the higher purchase.


  • Excessive variety of cost cycles
  • Maintains cost properly
  • Constant examined capability

  • KindThese are rechargeable AA NiMH batteries

  • CyclesThese batteries can final for 1000 cost cycles


The Ansmann MaxE AA 2100 fills out Ansmann’s vary of batteries, providing a barely extra mid-range capability. Efficiency and capability checks returned good outcomes; not solely do these batteries maintain their cost properly, they will deal with loads of recharges as properly. Total, although, these batteries are a bit of too costly; and you could find the higher-capacity Ansmann MaxE AA 2500 for the same value.

Design and Prices

  • May be recharged 1000 occasions
  • Maintains 80% cost over 12 months

Just like the Ansmann MaxE AA 2500, the Ansmann MaxE AA 2100 are designed to ship a very good mixture of life and cost upkeep. These batteries are designed to final for 1000 cost cycles, which is beneficiant for common rechargeable batteries. Compared, the standard Duracell Rechargeable AA batteries are designed for less than 400 cycles.

These are low self-discharge cells, which implies that they’ll maintain 80% of their cost for 12 months. That’s a very good outcome, and means you possibly can cost these batteries and go away them in a drawer prepared to be used if you want them. If you happen to do require an extended shelf life, then the Eneloop AA or GP ReCyko Professional AA batteries are a more sensible choice.


  • Excessive-capacity outcomes
  • Secure over a number of cycles

To check the Ansmann MaxE AA 2100, I used an Ansmann Power XC3000 battery charger. I began by testing voltage. For NiMH rechargeable batteries, this must be a minimal of 1.2V; right here, I measured voltage at 1.39V. Voltage does decline because the batteries are used, however what’s necessary is that they’ve a excessive sufficient beginning worth.

Subsequent, I measured capability. Though these batteries are rated at 2100mAh, I measured them at 2354mAH, which is spectacular.

I then cycled the batteries 50 occasions, taking capability measurements each 10 cycles. From the graph under, you possibly can see that the Ansmann MaxE AA 2100 constantly delivered higher capability than their rated worth, with little variance within the combine. Once more, these are spectacular outcomes.

These items are a bit of costly, and you will get comparable longevity and cost holding however with greater capacities for across the similar cash.

Remaining Ideas

The Ansmann MaxE AA 2100 are an incredible set of batteries, and so they’d rating greater if it wasn’t for the truth that the Ansmann MaxE AA 2500 can typically be picked up for the same value. Provided that these batteries supply the identical cycle life and cost upkeep because the 2500, I’d fairly go for the additional capability of the latter, even when I didn’t all the time want it.

These requiring extra longevity and an extended shelf life ought to go for the Eneloop AA or GP ReCyko Professional AA as a substitute.

How we check

Not like different websites, we check each rechargeable battery we assessment completely over an prolonged time period. We use commonplace checks to match options correctly. We’ll all the time inform you what we discover. We by no means, ever, settle for cash to assessment a product.

Discover out extra about how we check in our ethics coverage.

We use an Ansmann Power XC 3000 to empty batteries, in order that we are able to check capability in mAh. After the primary run, we cost and discharge 50 occasions, measuring the capability each ten runs.

We measure the preliminary voltage of the batteries, checking that the beginning voltage is at the least 1.2V.
