Why is it so difficult! to come through with a new and better product?
A Product millions of us use every day, we buy it and put it in a device, and don't think about the alternative, it have been like that in to many years.
We have been able to Charge battery in many years, but it haven't been easy to get the Rechargeable battery, and they have been very expensive, the recharger haven't been good, so most of the people there tried it, get back to the old battery again.
For that there can only be one reason, the production of the old batteries are a great business, no reason to change any of that.
To day it is easy to buy Rechargeable Battery and a Charger. and it works from day one, it can't be more easy.
Save the Environment for a great deal of chemicals, and your self for the a great deal of Money in the Future
