Sorry, the standard batteries were only 700mAh.Yes the 2700 milliampere-hour (mAh) last much longer when used compared to the lower rating.
I moaned that my camera batteries went flat in a flash and got told off by hubby for not buying 2500mAh version. Now in daylight conditions at an event with 4 2500 MAh batteries it will take over 400 10mp photos and last all day.
