How to check the continuous current of lithium battery
You mentioned a way by using LM317 to determine battery capacity. I need to check a lithium ion battery with about 1700mAh capacity. What do you recommend to me to measure this kind of battery capacity in a reasonable time like 3-4 hours. A 1700 mAh battery would be discharged in 3 hours by 1700/3 =~ 570 mA and in 4 hours by 1700/4 ~= 425 mA. - Download [PDF]
