A 12v Battery Pack was at 0V and wouldn't take a charge. Manufacturer Miady recommended starting up the sleeping BMS with a 9-volt battery across the terminals. I tried this -- it worked! Battery read just over 10V on voltmeter. Immediately connected to charger.
If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous.

If you want to charge the batteries up to 2V, maybe set the voltage to 2V then so it stops the current once it reaches those 2V. Be wary though: if the battery voltage recovers on its own to higher than the set voltage, the PSU will be forced to sink current, which most don't support.
Battery packs are made from many lithium-ion cells. So if one goes bad, it's more than likely going to negatively impact the surrounding cells. If left unchecked, a bad lithium-ion battery can overheat and go into thermal runaway, which is never a good thing.
Use a multimeter to measure the open circuit voltage of the battery and check whether the battery is in under-voltage protection mode. If the open circuit voltage of the battery is lower than 10V (for 12V lithium battery) or 20V (for 24V lithium battery), it means that the battery is in under-voltage protection mode.
