Ok, so the 2016 is supposed to have a 76 watt hour battery System information and coconut battery list battery life and design capacity in mAh. System information under battery power also lists the voltage as 12.8V. Design capacity from coconut battery for my 2016 15" battery = 6669mAh. Formula is (mAh)*(V)/1000 = (Wh). For example, if I have a 6669mAh battery rated at 12.8V, the power is 6669mAh * 12.8V / 1000 = 85Wh. Even if it was calculated at 12v the watt hours would still be over 80. To get ~76watt hours the design capacity would need to be closer to 6000mAh. What are the rest of you showing for design capacity in Coconut Battery?
