Batteries will all, at some point, get damaged by the recharging cycles, also original NP-W126 will ( run a search on line, several reports) albeit possibly later than third parties batteries.
My macbook battery swell up too (original part) and nearly destroyed the computer from inside this has nothing to do with parts being original or not. It has to do with the way some batteries respond to aging and repeated loading cycles.
Indeed even Fuji batteries are third parties batteries, Fuji doesn’t make them! They buy them under tighter specs than other makers but they are batteries like all others.
Duracell is a well known name but there is nothing in that name to suggest they are any better than other makers. They too will get damaged.
As soon as you notice bulging discard (dispose in appropriate manner) and replace.
As for batteries, quality varies greatly, have you read this?

the popular expression wishful thinking is an oxymoron!
To all TAPATALK users
As a form of courtesy towards your fellow users of this forum, PLEASE remove the obnoxious tapatalk signature, it adds nothing to anyone’s contribution and it is only a sneaky way used by tapatalk to push their product by polluting each forum participant with promoting their products with unpaid advertising for their software and the brand of your phone. Removing it is easy and it is an act of courtesy that shows respect for all those whom are annoyed by this pointless feature. This is not a personal attack to you, the annoyance is caused by tapatalk and the phone or tablet brands, they are getting all the exposure and you gain nothing by this.
