Title: 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:

https://www.ebay.com/itm/293697065501

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.
