STNS01 has a precharge timer of 30 mins. When this timer times out, does this indicate a faulty lithium ion cell?I understand that in the first place, lithium ion cells shouldn't be discharged to below cutoff to prevent damage (2.6-3.0v for most Li-ion). Is this correct?If statement 2. is correct, does this mean that "deeply" discharged batteries (Li-ion cells discharged all the way to 0v) are not always successfully charged by STNS01 (or similar charging ICs)?If this timer timed-out, is it better to assume the battery is damaged OR can we restart the entire charging cycle to try to recharge the battery again (ie., restart the 30 min timer)?

STNS01 precharge timeout

STNS01 has a precharge timer of 30 mins.

When this timer times out, does this indicate a faulty lithium ion cell?
