And for another $10 you can buy a AC timer at walmart to run it only an hour a day for the ultimate "fully charged batteries always at the ready" station.

As a public service I can post a schematic of a 8 cell AA NIMH trickle charger you can build in about 30 minutes for under $10. All you need is a wall wart power pack of sufficient DC voltage/current, two 4 cell battery holders, and a resistor of the correct value and wattage. About the simplest project ever. A six year old could build one.

The P&S often sits idle for a month or two before suddenly getting called into action. The Pentax gear usually only parks for a week or two (I'm more of a weekend road-warrier). I have active-noise-reducing headphones (Sennheiser) that will go for months with a couple of AAA's in them before I need the active circuitry to be powered. > I dont. > > I have three sets.

That's a good way to go, though it requires a few chargers. > I dont > need those kind of batteries and I doubt you do either > unless you actually only have one set of battteries > and like to charge them and then not use the camera for > weeks or months. > I have one good charger that I paid $80 for. I'm not going to buy several more, one for each battery set I have on trickle charge constantly. I have several sets of cells, in-camera and ready for use; in-kit-bag and ready for swapping with the in-camera ones. OK, we've identified that my usage and yours vary such that you have no need for these cells. I like 'em, they can be used like regular dry cells (some people put them in TV remotes), they work for me. They apparently suit a few other people too. -bmw -- 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. -- 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. -- 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.
