I am totally unfamiliar of overall performance and life cycle of Energizer NiMH.
Never had any, and I do not have any experiences of my own.
But by reading the datasheet of AA 2300mAh Power Plus (NH15-2300), I did spotted something
remarkable.
Energizer this did not hesitate to also test and deliver, technical specifications at discharge rate of
2C .
By 99% Energizer this is
the only manufacturer worldwide, that tested their product at
4.6 Ampere constant discharge rate.

I feel amazed and excited, because I am a constant seeker of worth talking about technology.
I am now sensing that Energizer engineers they run this test under the feeling of significant confidence, regarding the strength this hidden at their chemistry in use!
Most to all Chinese competitors, their products will be crippled if they were tested at 2C rate for a couple of times.
Attached the Energizer datasheet, for all Europeans to see, that
Panasonic eneloop this is not
the only one alive source of battery technology innovation.
