Design capacity is not 5200 mAh Real design capacity is 4350 mAh Capacity was tested by program acpi from linux
the battery only lasts 1 hour where it is supposed to lasts much more. I don't even know if it could be rated 2000MAH. vendor say to discharge and recharge battery, take it off and replace, nothing works. it's not my first replacement battery, bit it is the worst one. at least, I can move from a socket to another one!
