GVP A1230 Turbo+ II Battery
« on: February 03, 2010, 07:18:19 PM »
Does anyone know what battery is right for the GVP Jaws II?

The writing on the battery says:
DS TIC 1494 618AC 9310A5

The only result I get when putting that into Google is a Finnish Amiga user having the same problem. I thought it might be:

http://www.watchbattery.co.uk/shop/products/BAGP-625A.shtml

Based on dimensions, but I assumed it would be a 3V cell. Its only putting out 0.2v so I can't even tell you what it is putting out without seeing a circuit diagram of the board.

I have PM'd someone on amiga.org who said they had a pdf manual, in case its in there. If anyone else has a clue, please let me know. It is not as wide as a CR8032 and it is about twice the height (I don't have a micrometer but with a ruler its about 17mm by 5mm ish).

By Jove I think I have found it! Got a reply from Michael at GVP and he said it wasn't a battery exactly but a single wire RTC with a battery inside. They were originally developed by Dallas Semiconductor and now iButton develops them and other 1 wire devices such as ID fobs for EPOS systems to temperature monitoring and storage of data. Link.

Going from that site to the UK distributor (there are other distributors - see link above for links to other resellers), I have purchased one which I shall try when it arrives: Link.

I am going to try one of these new ones and see if the binary output is in the correct format. I guess the reason I was only getting 0.3v output from the chip is it is probably powering the internal circuitry and then sending pulses on the card, not sure if 0.3v is high enough though.... Interesting these clock in a cans!

**** Update ****

I tried the chip from the link above and it DOES NOT WORK in this card. Worth a try though. Whilst I had the GVP removed I tried the one that it came with and it was only out by one minute! So I have left that one in.... I thought it didn't have enough charge to even run the clock but now we know the clock is inside....

... if GVP have the actual ones in stock I will get one when I get my 2x16MB simms to replace my 2x4MB but everything is fine for now.

This is the product I needed. I just remembered the link after a fellow Amiga user emailed me asking did I resolve this (thanks Ken). The answer, yes! Its an DS1994 F5. Link

A link for those living in Australia who need a clock button cell for their GVP Turbo II or GVP Jaws II: Link
