If this should go to the developers forum, maybe a mod can move this thread?

A double failure is very uncommon, but they can happen.
But you don't have to presume a double failure here.
Just blame the 3G module for the "early" failure of the first battery.
(True, you still would have to replace both, but not require that the battery fail of its own accord.)
Keep in mind, even when operating normally, the 3G module pulls about 4x the battery's rating when it transmits.
Translation: Amazon includes the smallest storage capacity battery that can withstand the peak current surge demand of the 3G module.
I posted a lot of details on this subject right after I first joined here (5 years ago).
Those posts can still be accessed if anyone is curious (MR uses accessible archives).
