Interesting about optacon batteries. My comment this morning was about regular batteries you buy to use in radios and other portable equipment. I was wondering if there's a way to tell rechargeable batteries apart from non-rechargeables. I mentioned an example of Duracell energizers which are non-rechargeable, versus nickel-metal hydride rechargeables. Any ideas? Is there any print on them that the optacon can read? I haven't found any.
