This is a decent battery at a good price. I got 2,158 mA.h from a fully charged battery, discharging at 500 mA and stopping when the voltage dropped to 6 volts. If you go much lower, the protection circuit cuts you off. Although the voltage reads zero, as soon as you connect a charger, you're up and running again. The impedance is not that great, about a third of an ohm.
