Well I had a FAKE chip here & thought it's not really worth any value & a VERY wise person on this site had mentioned about opening them up & running a replaceable 3v supply....
So now I need to find a suitable supply I'm thinking it's going to be easiest to get a 3v cradle like what you find in most key heads (apart from VR-VZ commodore as there not replaceable].. supposedly) I'm guessing jaycar would have these cradles & then I can just replace the battery every few years & it's got the machined pin base attached to it so it should be good for 50 years or more I'm guessing.
Strange the FAKE DS1245Y actually had a good panasonic battery in it (thought they would have used a no name)!

Re: DS1245Y Frankenstein
Yeah you probably can do something like that. Keep in mind its not an industrial temp rated package (keep a burnt memcal tune in the glove box incase of corruption when the cabin heats up).

Re: DS1245Y Frankenstein
Maybe it was just like the outer case, labelled Dallas but not from Dallas. Plenty of dodgy battery copies around too.VX L67 Getrag wrote:Strange the FAKE DS1245Y actually had a good panasonic battery in it (thought they would have used a no name)!

everything is being copied to the finest detail there days.

Get a 3v lithium button cell battery with solder tabs, that way there's no risk of it popping out of the cradle.
Or get a 2xAAA battery holder from jaycar and stick a pair of NiMH batteries in it, and run two diodes in series from the 5v memcal supply to the battery holder's +
