When charging lithium ion batteries do they draw a stable current throughout the charge cycle? Say you have used the battery until it shut down. When you put it on the charger will it draw more current at the beginning of the cycle or will it draw more as it gets close to a full charge? Or is it constant throughout the range?
And the same question regarding heat. Usually current and heat go together, but I don't know if a charging battery follows this pattern. Will the battery heat up quickly at the beginning of the cycle and stay at that temperature? Will it get hotter or cooler as it reaches full charge?
