[Gta04-owner] battery problems

Hi,

I have these kind of replacement "batteries" for the gta04.

The right one works, but dimensions are not perfect and feels
more fragile. The left one worked shortly but then I had no output at
the terminals. There seems to be some problem between the gta04-side
battery - terminal and the B- test point.

A picture of the protection circuit is here.

As I do not have too much spare protection circuits, do you have
any advice what I should take better care of for the next one?

Furthermore with the right one looking at the display is easier
and I could check current consumption.

The whole thing is interesting because it would allow me to run
git bisect run with a closed gta04a5. Currently I am using the letux3704
for it.

Regards,
Andreas
