wrong item pictured in the description
on April 27, 2013
If you're looking for 850 mAh batteries pictured in the description these are not it. item #NH12BP4 are 700 mAh batteries. mAh or milliamp hours is unit for measuring electric power over time. mAh is commonly used to describe the total amount of energy a battery can store at one time. Obviously when one shops on line, compares products & prices, such a description is considered prior to purchase. The batteries I recieved are 700 mAh which will not hold a charge as long as the batteries pictured. I'm merely writing this review to create awareness, so Amazon can fix this issue, and get the right product pictured.
