It's a battery, it works, no space science
on May 3, 2009
It's a battery. It works. No space science there.
I bought these to replace the original about 5-year old 1100mAh Canon BP-511 battery that started to show signs of age. Old Canon's battery capacity decreased to the point where fully charged and with EF 100-400L IS lens fitted on camera, it wouldn't last till the end of my son's 30-minute soccer class.
These new batteries seem to be able to power my camera and a battery thirsty lens for a very long time. So, I'm happy.
Mine were shipped by bargaincell.com. As some reviewers already noticed, capacity is not printed on the batteries. Which is strange and unusual. I actually got batteries in two separate boxes (not one box with two batteries). Each box had SKU CAMCAN001 printed on it. Google search finds the page on the sellers web site that lists battery capacity as "only" 1600mAh.
Whatever the true capacity of these batteries are, they are still a great deal, and I'm definitely going to keep mine (I read reviews that challenged if these are truly 2000mAh before buying, so I knew what I going into). Unless you absolutely must have 2000mAh battery (currently selling for around $25), buy these and don't think twice. $7.34 for two is an incredible price. On the seller's own website, they sell single of these for $8.49! So grab two-pack on Amazon for the price of single battery while they still offer this deal.
The only complaint I have is that they do not come with plastic lid that protects contacts when battery is not in the camera. Luckily, my camera bag has handy compartments for batteries, so I don't really need those plastic lids (and I have one plastic lid that came with Canon's battery too).
The only reason for taking off two star is uncertainty what the true capacity of these batteries is. It's a really bad move on the manufacturer's and seller's part (taking one star off for each). Other than that, they work perfectly fine.
