I bought aftermarket EN-EL15 batteries. Are they dangerous?

[22khz]

Hello. I own a D7200 camera (maybe not the best place to ask this question) but
Usually the EN-El15 batteries, the genuine ones are rated at:
7.0v 1900mAh @ 14Wh

I bought a brand new which is rated at:
7.0v 2500mAh @ 17.9Wh


There is a significant difference, but Is it significant?
I don't care about money or sending it back, the shipping costs are the same as the price of this battery so I can just either leave it in my shelf or throw it away in a battery recycling bin
I perhaps made a bad mistake.

My question is very simple, Is it dangerous for me to stick it in my camera? It's not a cheap camera and I don't take any risks, and I'm concerned if it may "fry" the main circuits of the camera because of the either increased mAh or Wh.
I would like to be educated. If it's too dangerous.

No, this difference does not make the batteries dangerous. Basically, your after-market batteries have more power in them so they should last longer.

However, depending on the source, the danger doesn't come from what is listed on the outside but rather on the construction inside.. I like to stick to original Nikon batteries for my DSLRs...

I stick to genuine batteries too. No point in skimping $50 here and there on unknown batteries when my main bag (if full) is worth 25k.

I’ve got original Nikon batteries from my old d200 that still hold nearly the full capacity and they’re 11 years old now.

Nope, it's typically just "quote the biggest number so people buy here" kind of deal, they actually have similar or less real capacity than the original.

I've used aftermarket batteries for all my cameras in the past 10 years and never had an issue.

I've also used aftermarket batteries and never had any trouble at all.

You could stick a 25,000,000,000,000 mAh battery in there if such a thing existed and it would work just fine. The mAh and Wh ratings indicate the capacity, using a battery with a higher mAh rating is like putting a larger fuel tank in your car, the engine will still use the same amount of fuel, it just has a larger supply of it available.

I know there are plenty of aftermarket batteries that works just fine and are well within spec. The problem is that just because it has worked for some of you, doesn't mean they are all good. Basically, one has to look at the source - if it is sold by a trusted source, it is probably fine, but there is still a bit of gamble involved, even if the risks are low.

At least in my case, the original Nikon batteries are cheap enough that it makes no sense to buy anything but those.

I thought about buying clone batteries for my D50 (ancient) but the original Nikon one is still excellent, would definitely recommend buying original, it's just false economy not to IMHO.

As everone's said, there's probably nothing wrong with them. They might not be the higher capacity, probably the same.

Have you done any objective tests, comparing the two? If the answer is no, your judgment can be clouded because you want to think they're better. If the answer is yes, could it be because the older batteries have worn out a bit and the newer ones more fresh?
