Duracell sent me a few of their new pre-charged batteries to try out. The idea is that people don’t purchase rechargable batteries because they need to use them right away. In the past you couldn’t pre-charge Ni-Cad rechargeable batteries because they would lose their charge while sitting on the shelf. The new pre-charged batteries seem to overcome this problem which also means you can charge up the batteries and not use it for awhile without losing power. I’m still testing them out to write up a better review of their performance. Duracell seems light on stats for the batteries with most of their efforts going into marketing based on humor, however the product seems good and will probably convert me back to using rechargeable batteries after a long hiatus due to the short comings of Ni-Cad technology.
