The overall consensus is to use eneloops (with a good reliable charger).
There are confirmed re-badged eneloops -
important: look for the white top surrounding the +ve button, and made in Japan - only these are eneloop clones-
Duracell Pre-Charged
Sony Cycle-Energy
However almost any LSD (
Low Self-Discharge) NiMH from a reputable brand will also be fine -
Brand names for LSD NiMH batteries include:
* Prolife from Fujicell
* Ready2Use Accu from Varta
* AccuEvolution from AccuPower
* Hybrid from Rayovac
* eneloop from Sanyo
* eniTime from Yuasa
* Infinium from Panasonic
* ReCyko from Gold Peak
* Instant from Vapex
* Hybrio from Uniross
* Cycle Energy from Sony
* MaxE and MaxE Plus from Ansmann
* EnergyOn from NexCell
* ActiveCharge/StayCharged/Pre-Charged from Duracell
* Pre-Charged from Kodak
The aforementioned Uniross Hybrios - some are also suspected re-badged eneloops - again look for the white top surrounds, although sometimes they may not be marked made in Japan.....
I use eneloops and DuraLoops (unofficial nickname of Duracell Pre-Charged - clones of eneloops)
on average I get over 1,100 shots in my K-x -
