Does this match the datasheet of 3000mah for the official batteries? These seem a little sketchy for our important high-altitude research.

What I received does appear to be L91 batteries identical to what I am replacing. The data sheet for the L91's does show 3000mah, but I don't have any way to prove that they are performing to that specification. I use them in an outdoor application and they have performed well; even in the cold (20*C). They are rated at 1.5 Volts, but actually measure at 1.8 Volt. So far I only have 12 of the batteries in use, but they are performing fine.

How would I go about conducting such a test? I don't think it would be worth the time and/or effort to do it.I also have a pair of these batteries by Philips, and a pair of Rayovacs, and two devices that use them, and I don't find any noticeable difference in performance.

Not to come across as a smart a.., if it says don't use above 2000mah, why would you?? Having said that, I bought my battery and charger as a matched kit, so they were compatible. You might look to see what charger works with your battery

Close up, the picture shows the battery brand is "Niceshopping" and the capacity printed on the battery is 3000 mAh. This price is so far below the reputable name brands that I would not expect much from it. Many no-name vendors are wildly overstating the capacity of their batteries. "If it sounds too good to be true..."

I just got some of these batteries for my Propel SpeedStar, and tested it, the shape of the connector is a match, as is the voltage. The increase of 40 mah will give you more flight time.

Truthfully i didn't pay much attention to the mah number. On amazon i entered the phone type and weeded out the battry from there. The battery was a bit different than my original in that the connector was 2 separate pieces instead of 2 wires attached to one connector. I hope this helps at least a bit

I agree with Mr. Young.. mAh is just the capacity and has nothing to do with the actual output.. it's the 2.4v that's important. In theory, this battery should last a but longer than an 800mAh, but battery manufacturer specifications of their battery capacities are not always correct. At the price, these batteries are a great deal!

They aren't even 4000mah @ 500ma discharge rate. They don't even have the (advertized) capacity of 18650's. After a few charge/discharge cycles they (4 cells) average out at about 3150mAh. The lower the price, the more creative the advertizing.On my charger the mah in is only about 3200mah. Did they not say the 6000mah was TOTAL for the two batteries.

I ordered two. They work perfectly. The higher 2400ma means they have more capacity - last longer. However, be careful when ordering. There are two different models with the same part number. Insure that the contacts in the picture looks exactly like the contacts on your current battery.

The cells inside the one I bought were marked 2600mAh, so definitely not the rated 3300mAh. That said, it seems to last ages. I've had one consistent problem using this in the Smatree battery grip for the D800: if the battery in the D800 is low or dead, then regardless of how charged this battery is, entering Live View will show ERR. Have to release the shutter to clear the error. So if you use Live View a lot, might want to look elsewhere. Also possible I got a dud, your mileage may vary, etc.

I think the volts (V) is the number that needs to match but the mAh does not. In fact, if the mAh number is higher than the original battery, you should notice improved performance.

I never heard back from this vendor. I kept the 800 mAh batteries that they sent because returning them would have been more of a waste of my time for a $10 purchase. They are reasonable for the price, but misrepresented by this vendor. Don't expect them to send the 1000 mAh version.

In the batteries, under + and size AA you can read 2300 mAh. It's true ??? I don't know exactly
2264742
Kind of weird that Amazon would leave that information out, as others have stated, they are 2400, if you click on one of the photos it shows the 2400mAh on the battery itself. If you contact Amazon about showing that information they might update the page to include the mAh number.

I'm not sure if they are or not, they had Chinese(?) writing on them, which doesn't necessarily mean they are counterfeit. They worked for me, but didn't seem to last as long as other Duracell batteries I've purchased.

The battery I received here is marked 7800 milli Amp Hour, and should be the correct one I asked for. The only way to know for sure if is what is printed on the battery is a standard load test. a problem for most to perform. I usually trust what is printed unless performs poorly in the machine. my past experience is usually good to what is printed. good luck, I felt I got what I asked for.

It does say 1200mAh on the batteries I received, but I returned as they would not charge.
