I am using li ion single cell in one of the application where device will be in sleep mode when is not in use. Life time of which is nearly 30 days.
Cell I am using is Li-ion, 18650 package, 2600mah and comes with "1s 3.7v 2a Li Ion Bms Pcm 18650 Battery Protection Board Pcb". For charging I am using TP4056. It is set to charge battery at 500mA.
My concern is if because of some reasons cell goes below its rated and fall into deep discharge, would TP4056 be able to charge it again up to usable voltage ?
Is it should be happening ?
Any other ways to prevent this situation ?
