BL-6C: 1150mAh. And that's probably as good as it gets for cells fitting into 
GTA02 battery bay. Unlike NiMH the LiIon technology hasn't made noticeable 
evolution during last few years. When searching you may find a 2nd source 
battery that has a *real* capacity of maybe 20% higher. You will need to 
discard 95% scam before you find that one manufacturer.
