How many hours does a …
Because lithium-ion batteries can have a variety of positive and negative electrode materials, the energy density and voltage vary accordingly. The open-circuit voltage is higher than in aqueous batteries (such as lead–acid, nickel–metal hydride and nickel–cadmium). Internal resistance increases with both cycling and age, although this depends strongly on the voltage and temperature the batteries are stored at. Rising internal resi…
How to calculate the Watt Hours (Wh) of a lithium battery
example 1: an 11.1 volt 4,400 mAh battery – first divide the mAh rating by 1,000 to get the Ah rating – 4,400/1,000 – 4.4ah. You can now calculate as – 4.4Ah x 11.1 volts = 48.8Wh; example 2: a 12 volt 50 …
