Almost all 3rd party batteries, while of the correct voltage, will over state their capacity. The manfs do this deliberately to entice you to buy them.
I don't understand the OEM battery manfs or the camera companies they make them for. Over the years you can buy from power tool manfs a range of capacities ranging from 1-2AH (usually sold for use in kits to claw back the profit they loose by clumping several power tools together at a lower price for each piece) up to perhaps 6AH for which you will pay a premium but get much longer run time (power tool batteries are the new OEM ink cartridges). The batteries are sold by the manufacturers and the ratings are usually correct.
So why can't you do this for your camera as battery chemistry and manufacturing process's get better. I think you will find it is because of two reasons -
1. Because they don't need to. Why make a larger capacity battery when they hope you will just buy more of them at their extortionate price and
2. Why devote any R&D time and money to it when they are already developing the next generation of camera.
You are screwed and they know it. Power tool manfs have to because a battery style must last several years and purchasers will just stop buying that manfs tools and change brand if it turns out the manfs are dicking around with batteries just to make more money.
3rd party camera battery suppliers also know it hence trying to cash in on the desire for larger capacities. I have even caught a supplier heat shrinking on false labels claiming a higher capacity. It is an industry wide scam and it will continue until you stop buying falsely labelled goods AND insisting the OEM supplies the higher capacity goods at a more reasonable price.
Now down the track I can see all OEM suppliers making the cameras so that they will only run with their own supplied batteries (and I think a few are already doing just that). Then you watch the prices rise. Personally if that happens I will just stop buying that brand.
I am not cynical just a realist.

Over the years I've tried to save money by buying a quality non OEM battery. I've been disappointed more often, so in 2017 I decided to buy just OEM batteries. Never been disappointed,

If anyone thinks that Canon, Nikon, or whatever have their own battery factory, I have some waterfront land in Florida to sell you.

As I teach my fall physics students, as we study electricity, when your "source" of electricity offers a higher source of amperage than you need, it simply means that the electron count is there...for you to use as you need. Remember, normal branch circuits offer 15 amps (USA). You frequently connect a lamp that draws only 1 amp, or in the case of an LED lamp, maybe 0.4 amps. The 15 amp source is still there, should your application call on it. The same is true for batteries. Oh, my favorite example is a friend ... typically called on by friends in the dead of winter...for a jump start. On his newest truck, he installed a second 12vdc battery wired in parallel with the trucks original 12vdc battery. So he now has twice the amperage, available to be used. And notice the word "available". That is how our batteries work, be in a camera with one battery, or a camera with a power grip using two batteries (wired in parallel circuit) or multiple batteries in a flashlight. Wired in parallel, voltage stays constant, amperage is increased. Wired in series, voltage goes up, amperage stays the same.
Sorry for the physics lesson guys, I just thought I'd share information perhaps all can use. Which means that everyone who said a battery with increased "amperage-hour" will be fine, and they were right on the mark. Voltage is the same as one with lower "amperage-hour", but that higher one will offer the electron supply over a larger amount of time.

All this advise is correct. However, my experience indicates that non-OEM batteries never last as long as the OEM ones, regardless of the rating.
Quality? Way of measuring capacity? Lies?
Anyway, I use non-OEM as backups. Also, even with non-OEM, buy brands, not countefeits.

I'm a strong believer of OEM products, especially printer ink. I'm suspecting it is also true for batteries. I wish Consumer Reports would do a study of camera batteries.

True. Canon's batteries are made by Sony.
Oops! By Panasonic, not Sony. My morning coffee hasn't kicked in yet!

How did you learn that? I'm curious.
If that question is directed at me then the answer is: By reading the label on the battery.

It's okay as long as the voltage is the same. While the voltage is a measure of the power output (horsepower in a car), the milliamp hours (MaH) is simply the capacity of the battery, (gas tank size in a car). A 2200 MaH battery will simply last longer than an 1850 assuming the voltages are the same.

I get your analogy to correct the other fellows thinking, and you are correct. But watts (power or approximately work, still not precise) is like Work or Horse-Power.
Electrical Power = AxV
Wattage = amperage x voltage
MaH is a measure of how long it takes the battery to drain (you have the precise

My experience as well. The ratings are inflated to get you to buy the non-OEM product. I have decided to purchase only OEM for my Sonys and even then only from B&H (though any authorized dealer should suffice). The same for my Sandisk memory cards. Too many counterfeits.

They inflate the mAH rating because there are so many ways that you can test for the rating. If you make a test and discharge the battery at lower rate you will have a higher rating.
