I cannot tell you if the LPC worked properly but you should not re-use a battery that has seen reverse voltage.
All Lithium-XXX Batteries start to get damaged irreversible below a certain threshold (2V ish) and no Battery likes to get reverse charged.
It will start to chemically change. The electrolyte will start to break down (form gases and may bulge the battery), Lithium will get plated onto the anode, the internal resistance increases and capacity decreases significantly. If you reuse the battery you just make the issue worse.
Best would be to replace it and match all batteries by capacity to avoid reverse polarity.
Reverse polarity normally happens if you use batteries with significant different capacity or damaged cells or no BMS or a system that doesn’t fully cut off the current
