Lithium-ion battery capacity test

I did a capacity test on my newly imported lithium-ion battery: Type DC-12680 the capacity is supposed to be 6800 mAH.

The image below shows clearly that the capacity is only about 2400 mAH i.e. 1/3 of the advertised capacity.

The battery has been on charge for 9 hours since then and is still not fully charged (Red LED still on). I therefor assume the batteries cannot be recharged at a high rate. 

It is unacceptable that the capacity is so much lower than the supposed capacity.
Rapid recharging is not possible with the provided charger.

IMHO they are still worthwhile considering. They are compact and weigh almost nothing. This is ideal for back packing with ultra-light QRP equipment.
