    I'm using these in a flashlight mainly as a cost control measure. The money saved over drug store prices will cover the initial cost in 3 recharges.

  10. RCR123A rechargable batteries....

    Posted by Paul on 20th Mar 2013

    [...]The price was the best that I found for the type of battery that I needed. The batteries are used for a personal ionizer and they work very well. They last for several hours on a charge and then recharge within a very short period of time. I am quite happy with the batteries and the company!
