These batteries are a very good value, They have a protection circuit built into the base. When checked they may not be 4000 mah as advertised but about 3500 mah plus. After a few charge/discharge cycles they may be 4000 MaH. The protection circuit board may limit full current draw but they work very well in the 7 led SKYRAY flashlights I have which use 4 of these cells in parallel which works out to 16,000 MaH. Good bright light. Long duration . Still strong after 1.5 hours/
When placed in the center of a room they produce 430 LUX (MEASURED WITH A LIGHT METER) under the beam reflected from an 8 foot ceiling. Bright enough to read a book by. and ideal when power goes out. Happened here recently.

Although we only order a few things from you guys, we have always been very satisfied with our products and service. Considering that our Nursing Home is Located in Alaska, it is truly amazing that we can receive our purchases in less than a week's time. In regard to these batteries, we are very pleased. Having a 4000mAh rating gives the flashlights (which we also purchased from MiniInTheBox) that added power and length of use between charges we need. The price is also a great deal in comparrison to what we would pay at the store just down the road. So far we have ordered about ten pair of batteries and will probably order more. Thank you MiniInTheBox!
