Lets say that you have two sets of batteries so you always have a spare charged set. And lets say that you shoot 300 frames a day, or that you have to change batteries every day. With a thousand charges you get three years of use, being 1/3 less likely to run out of charge at an inconvenient time. What also matters is the discharge characteristics, how the voltage drops off with time, how the current does etc. I'm definitely going to give them a try for my next set of batteries. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
