Look at interesting product! That's exactly what I thought when I ran into this battery “Green” that can be recharged with water. Comes in this interesting and beautiful packaging with a syringe.
The syringe is really small, about of 0.6 mL as indicated in the instructions. You have to take the utmost care when filling the batteries because I always end up leaking a little.
The instructions are totally crazy. Start by saying that this is not a battery any. Should not be. I cannot understand very well what to do.
All I know is that I became ill. I tried to put all the water way and as much as I can is 0.6 V. Far of 1.5 V required to use somewhere.
Even worse is that the battery leaks the damn water, and it gets oxidized with time. I threw it all away! We don't always do well buying products from china. For those who want to get in trouble, I leave the link to the DealExtreme:
