Pros: I have used theese few months and I have allways power when I need it.Low selfdischarge I damn good when using theese on wireless mouse/keyboard.In my country theese cost like 16 euros, here under 10 euros.
Cons: Nothing!(or maybe those should have little more charge than 2100mAh)
Other Thoughts: Also I use theese in my external flash and now when sun shines I don´t use it much.But when comes a situation where I need flash, I know it´s ready for use because I have theese recykos inside.
Bottomline: If you need AA batteries anywhere, buy theese ones!
Item includes:4 x GP ReCyko+ AA batteriesHow was the self-discharge reduced?
Modern Ni-MH batteries consist of two metal stripes ( anode and cathode ), which are separated by a non-conductive porous plastic foil ( separator ). These three stripes are laid on top of each other and are winded to a coil. This coil is put in a metal can and immersed with a liquid ( electrolyte ). Then the metal can is closed with a cap.
The self discharge of Ni-MH batteries is caused by three main reasons:
- The chemical decomposition of the cathode,- The natural disaggregation of the anode,- Impurities of the anode.
Now, how could the self-discharge in the ReCyko+ been reduced?
The chemical decomposition of the kathode has been reduced substantially by the use of a new superlattice alloy. As an additional benefit the superlattice alloy increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents. Another advantage of the reduced decomposition of this alloy is the fact, that less Cobalt is needed to stabilize the alloy. The anode has been strengthened by another new material, which reduces the natural disaggregation. Additionally the separator and the used electrolyte have been optimised for low self discharge of the ReCyko+.
