Should i go for a third party one ( Duracell) or should i stay put ?
You should do whatever makes you feel good.
Lithium batteries can cause serious damage to people and property when they fail. "3rd-party" (actually un-certified look-alikes of unknown origin) have a much higher failure rate. So you may be lucky or unlucky with the units you buy. It's a bit of a lottery ticker. Like driving your car without tying your seat-belt, which makes some people feel good. For a while.
And I would like to see any data supporting such claims.
Aftermarket Li-ion camera batteries are made by the same untraceable factories as aftermarket Li-ion cell-phone batteries.
my personal solution is to have ZERO trust in OEM or third party.
best to just charge for an hour or two hours and pull them. a factory tech told me a long time ago not to leave batteries on the charger, which he felt were the number one reason for failure.
not wanting to burn my house down, i pull the batteries off the charger whether they be camera batteries or cordless drill batteries.
no batteries are charged while sleeping is the best rule.
another rule i follow is to use Good Third party batteries. Kastar and BM have panned out for me, so i buy them from amazon.
they haven't failed yet, but my Canon OEM battery has failed. i prefer OEM batteries but my experience with them is not consistent. YMMV of course.
seems two people can buy the same battery with two different experiences. but that is Life.
best way to defend against batteries enlarging in camera is to buy cheap used DSLR, so far no problems. if there ever will be a problem, oh well it was a cheap camera anyway.
expensive camera. eh, LOL get the OEM of course.
i like Kastar and BM because amazon always has them; they are cheaper than dirt, the charger is cheap and they work....plenty to like.
however i prefer OEM charger, but some people can't hang onto them when buying a used camera. hmmm are they failing or chargers just walk away some place? meh, still a mystery.
a real solution is to have AA batteries in our cameras, but that isn't gonna happen cause the OEM companies make to much money from the 2nd battery.

Thirty-three aftermarket battery brands (totaling over 1,200 battery pack and cell samples) were assessed against key evaluation and test requirements from several regional battery standards. None of the battery brands purchased were safety-certified to the applicable regional standards. Twenty-nine of the 33 (88%) battery brands exhibited failures to such standards.
All of the failed battery brands exhibited fire and explosion events either at pack or cell level.
Edit, another strategy is to use the third party battery only as a backup; most of the time my shooting is on one battery anyway, so the extra battery remains a non issue and does mostly away with battery fears.
if your the type of person who doesn't care for equipment or drops cameras et al, then stick with OEM. on these forums i frequently recommend a simple wrist strap instead of dropping a 5,000 dollar camera, groan. dropping cameras make for interesting stories of course, and wrist straps do not. oh well.
sorry i don't have a good 'dropping my camera' story to tell you.
