Recharging Over-discharged LiFePo battery

I want to confirm my Blue Smart IP67 12/25 is properly trying to recharge my over discharged LiFePo battery. My volt meter shows the battery having 9.5 volts. With the charger connected app monitor shows it to be in Absorb mode and a voltage of 14.2v. This was the same setting/voltage of the previous battery connected to the charger, which is brand new. I understand that to recharge an over discharged battery it's with low amps for a long time.

Recommend you set the charger to operate as a power supply at 12.00V and 10A:

BMS is likely in protection mode, and it won't wake up unless put in parallel with another battery, attached to a power supply or forced to reset in some manufacturer-specific way.


Your understanding of "low amps for a long time" is incorrect. Just charge it.
