Mr. Woodgate's response below and Mr. James's response are both to the effect that regardless of design, someone will build a dumb battery that is a form, fit but not quite fully functional replacement for the smart battery.
My experience runs counter to that. Years ago, before I wised up and quit buying ink jet printers, I decided to buy cheap ink replacement cartridges off the internet. These replacement cartridges were indeed form and fit replacements, but there was either the lack of an IC or the lack of proper information in the generic cartridge IC that prevented operation on my printer. Net result was that I had spent about $30 on cheap but unusable cartridges. So it seems to me there is a way to force usage of the proper battery, without relying on customers to make the "right" choice. Of course in my case I quit buying inkjet printers, but that venue isn't realistic with cell phones. > From: John Woodgate <[email protected]> > Date: Tue, 3 Apr 2007 14:27:24 +0100 > To: [email protected] > Subject: Re: Product Safety - "Smart Batteries" > > In message <c237bb41.52d6f%[email protected]>, dated Tue, 3 > Apr 2007, Ken Javor <[email protected]> writes: > >> If the smart battery is a safety issue, then the smart battery fit >> should be different (by industry standard) than a dumb battery >> replacement, so that the consumer is unable to accidentally or even >> intentionally replace the battery incorrectly. > > It doesn't work; the Sum Yung Gais just copy the shape, and if one > company is successfully ousted for patent or design infringement, > another starts up 24 hours later. > -- > OOO - Own Opinions Only.
