They are outsider my definition of cheap, but I did not find any alternatives. For god solderability use the recommended footprint and propper wetting of the soldering is important for mechanical strength.

Thanks! I've already seen these but they are not suitable as they don't actually snap to the battery so I need to use some sort of trick in order to get the battery to stay in place :( I think just using epoxy on the joints is the best solution here.

Psi:
Is this of any use?

If the wires are part of the holder they wont move much and can be very short before attaching to PCB.
So the risk of movement causing a wire break is very low.

How about using third one on the other side of the battery to keep battery nicely positioned and a bit of double sided tape on the board to glue battery on?
