After a full charge with the charger delivered, I measured the capacity of the 4 batteries at a constant discharge current of 100mA. Their capacity was in the range of 2890...2960mWh. Not quite the 3500mWh promised! The measured capacity might be different at different discharge currents, though. The voltage remained extremely stable during the entire discharge time within a range of 1.495...1.510V. It drops suddenly to 0V at the end of the discharge, so, if you are using the batteries in a device that shows the remaining capacity (e.g a camera) the device will always show "full capacity" until the end of the discharge, when it will suddenly quit service. If this is critical, you better carry spares.
