G4 Titanium PRAM Battery Source?


My G4 Titanium Powerbook is getting forgetful in it's old age, does anyone know a good source in the UK / EU for PRAM batteries?

Just bought 2 from seller in the UK off of ebay:

Not that easy to solder in on the circuit board, but seems to work once installed.

Note the way to determine positive and negative sides of the battery.

Seller's  description:

 Also Known as:  Panasonic CGL3032 3.7V, LIR-3032, LIR3032, KL3032, L3032, ELIR3032, KLIR3032, E-LIR3032, KELIR3032
VOLTAGE: 3.6 / 3.7V

DIAMETER: 30.0mm  THICKNESS: 3.2mm

LIR3032-VDY2 tagged lithium button cells are commonly used in car security, organizers (backup battery for PDA), computer equipment (memory backup battery), toys, communication equipment, and so forth.
The solder tags / pins allow these LIR3032-VDY2 tagged batteries to be soldered into electronic equipment whilst minimising the potential for the heat to damage the lithium cell.

The pins are for horizontal mounting on a PCB. The two pins are 33.4mm apart and positive pin is  wider (2.8mm) than the negative (0.75mm) and that the downward pins are further apart than the diameter of the cell.
