Though the Ansmann MaxE AA 2500 title suggests a 2500mAh capability, the field and batteries clearly additionally state that the minimal capability is 2400mAh. It’s a contact complicated, however the necessary factor to notice is that these batteries are comparatively excessive capability, as my efficiency assessments (under) reveal.

What’s nice about these batteries is that they’ll deal with as much as 1000 cost cycles (charging and discharging). That’s a beneficiant quantity, since most traditional batteries are rated at nearer to 500 cycles. Solely the Eneloop AA batteries supply much more cost cycles, though they’ve a lot decrease capability. 

Ansmann states that the MaxE AA 2500 can maintain as much as 80% of their cost after 12 months, so that they’re able to being charged after which left to sit down in a drawer till you want them. To be used in lower-drain gadgets, equivalent to a clock, these batteries with nonetheless final properly, since they received’t lose quite a lot of cost per day via pure attrition.


  • Performs properly in my assessments
  • Maintains efficiency properly over a number of fees

I used an Ansmann Vitality XC3000 battery tester to check the Ansmann MaxE AA 2500. First, I measured their voltage, which for NiMH batteries must be a minimum of 1.2V. I discovered that these batteries have been 1.29V when totally charged.

Subsequent, I measured capability with a high-drain load of 600mA (+/-20%). Initially, I noticed a capability results of 2646mAh, which is each above the minimal, and the “2500” within the title.

Subsequent, I cycled the batteries 50 instances, taking a capability studying each 10 cycles – the outcomes are offered within the graph under. As you’ll be able to see, the outcomes present a level of fluctuation, however there’s no signal of the batteries beginning to fade. With a lifetime of 1000 cycles, that’s accurately.
