How to Test Lithium Ion Battery with Multimeter

A lithium-ion battery is considered to be depleted when its voltage drops below 3.0 volts. If you measure the voltage of a lithium-ion battery and it reads below 3.0 volts, it is time to recharge the battery. How can you measure the current (in amps) of a lithium-ion battery with a multimeter? To measure the current (in amps) of a lithium-ion

batteries

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.
