Alpha R1, UK, purchase CMOS battery?

Take apart the old one and solder the wires to new one with solder tabs.  Then wrap in heat shrink.

Personally I would also hack a hole in the bottom so I dont have to disassemble the whole unit.

or use this method with copper tape.

Cheers mate. I thought that would be the case. Do you know what battery would be best. The guy in the video has a 3v version of a cell battery. Is that too powerful? I wondered how long a battery like that would last also.

What does it look like and what is printed on it?

I believe its a 

CR2032 CMOS 

I want to make sure before I start taking the machine to bits I make the right choice.

I have the R1 alpha aka its a steam machine ASM100  same thing.

The battery is in blue or black heatshrink its a CR2032 with wires and a tiny connector. 

DCR2032W-2PNMP
CR2032CL-23-2

No Idea why they didnt use a regular socket or why they make you explode the thing completely apart to get at the battery.

After getting apart I Cut a hole in the case and the metal bracket so that I dont need to disassemble each time.

Cheers for the response. I'll put a new battery in. I'll bite the bullet and buy from the US. I guess I could put a cheap battery in but to be honest I want something a bit more permenant. I've ordered copper tape and a some insulation tape, and a heatshrink sleeve. Hopefully that should be sufficient.
