Mark, I don't know squat about batteries, especially these newer types, however, I recall reading somewhere that rapidly charging a battery is not the ideal way to recharge, and that doing so can shorten battery life. IAC, it's always been my impression that a slower charge is better for longevity. I just wonder if there's any truth to that, or if there ever was.
That said, the rechargeable lithium ion bats that are in the various Sony cameras that I've used have lasted a very long time .... years, actually. The bat on my first camera lasted three or four years before finally getting to the point where it wouldn't hold a charge for a long time, and the bats in my current Sony, which are at least two years old, are still going strong. In both instances the charging process used is on the slow side, taking about four hours or so to fully recharge. Shel > [Original Message] > From: Mark Cassino > From: "Alan P.
