Sorry, not really an answer to your question.
Yet; you don’t have to get rid of your FP1 just for a broken battery. Try this one:
There are quite a few possibilities right now:
- Generic Huawei HB5N1H; various suppliers on amazon
- Jubatec battery; seems to be a generic Huawei as well, but is advertised for FP1 and the supplier will offer a spacer in march
At one time there was a swiss shop, that sold one of those generic batteries wrapped with a spacer in such a way, that it fit into the battery compartment.
This offer seems to be available no more; maybe because it was critizised in this forum for not offering any warranty.
