Identity of backup battery wired Leadtek 9532 (Tomtom)

[Heyou]

Anyone know what this batteries identity is??

It's on the underside of the circuit board, i didn't think there was battery at first it's so small, and it's what's causing my wired GPS to take forever to get it's first fix.

Description :-
The only things written on the battery are :-
on the side of it "0302"
on the positive face :- "IIS" and "made in Japan"

It may have more writing on it but it also has 2 circuit board solder tags spot welded to it, covering up any more info. I think, i've worked out that it's 3 volt?? by plugging in the charging unit and measuring the voltage coming from the battery whilst it's on the circuit board!! but of course i may completely wrong about this.

It never gets to above 2.5volts after being on the DC supply and remove the DC supply and it drops down to .6 volts within a few hours.

I've emailed Leadtek, no response, and i guess they won't tell me what the battery anyway, only that they'll repair the unit for a price!! I know i can fix this if only i could source a battery for it.

So what i'm after is - 3volt ? - 6.5mm Dia. X 1.5mm height.
I'm pretty sure it's rechargeable.
It has 2 solder tags on it but i won't hold my breath - i could modify it to solder it to the circuit board.

cheers

Del.
