Having purchased this battery, I reviewed it based on the fact that when I used it in my camera, occasionally during the shoot, the camera simply wouldn't fire. I'd then turn the camera off and then back on, shoot a few more frames, then same thing. I've since acquired another Canon brand battery, and retired this one to use as a "backup backup backup." After all, you never know, and if you truly run out all of your batteries and still need to shoot, having an unreliable battery is still better than having no battery at all. How long does the battery last? Can't say. . . got too frustrated with its unreliability to keep using it until it died. Sorry.

I use a battery grip that holds 2. I can shoot an entire wedding without changing batteries until about half way through the reception.

FYI to anyone wanting to extend the life of this unit. Reading the manual, it states you should leave this pack sit with about a HALF charge and use it at least once a month. Once/week is better. Inside are two 2600mAh Samsung Li-Ion cells. Li-Ion batteries HATE being charged and being placed somewhere to sit or else they commit suicide!Mine is over a year old and still working fine. When not in use, I usually charge my iPhone from about 30% to 100%, then recharge the battery pack so it's somewhere around 50-75% charged. I try to do this once each month since I don't use it a lot.

No...because 5300mAh batteries do exist yet. 3600mAh is the maximum real rating, anything higher is lying to you. Get a known brand for real mAh ratings. I have compared Panasonic 3400mAh vs "5000mAh" batteries, Panasonic lasts about 6-7 times longer, showing the "5000mAh" batteries are really 500-600mAh.

I also agree with Andrew. I bought this battery and simply installed it and it has worked fine ever since (more than 3 months now). I went from about 6 hours per day of life to now about 12 under normal use.

I'm not sure what you might find to be the difference. However, I do know that my 4400 mAh still lasts me over 5 hours of intense use, and I've been using it daily for almost nine months I believe. Either way I don't think you can go wrong!

These batteries don't have the capacity to hold a charge for very long. This one actually has a little more capacity than the OEM. I get an hour or more with it at least and about 20 or 30 minutes with the original that came with my computer. It also charges fast.

You would have to check with B&D. I looked on the battery and the box it came in and could not find anywhere what the mah rating is (which is kinda strange). I can report that they do last a long time.

The key is the 11000 mAh, they last longer between charges. I bought six and am planning to buy more.

It should as long as your battery is a 3.6volt type and the plug you have looks just like the one in the photo. The 400- 1000 m/Ah rating only has to due with how long it will hold a charge when off the charger base[higher the # the longer it lasts] Bat. pack measures 1 5/8" by 1 1/8"

The 2200mah allows for more battery hours which is why the performance of this battery is better than the mfg original battery. Although they claim that at times higher mah can make for a larger or heavier battery, I did not experience that with this battery - fit perfectly. http://www.phonescoop.com/glossary/term.php?gid=194

I am very happy with this battery. It works perfect. I get up to 6 hours of use. Hope this helps.

Hi Meghan, I doubt anybody would take time to compare and find out how long it lasts. To me, they are the same. I have been using generic battery as long I can remember. No problem so far.

it will last the same amount as the org. Battery. No problems from this battery

I'm not sure. Cannot locate the information but if you have questions contact them. Our battery seems to be performing well. MM

It lasts about 10%-20% longer than the OEM battery. I ended up not using it because of the extra weight and little benefit.

Depends on the battery you are using. I had a 2000mah wich lasted ahout 7 minutes now im using a 4000mah that lasts abou 13 minutes. If you want more airtime buy a couple of batteries.

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.
