Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
3.2.2 Lead-Acid Battery Materials. The lead-acid battery is a kind of widely used commercial rechargeable battery which had been developed for a century. As a typical lead-acid battery electrode material, PbO 2 can produce pseudocapacitance in the H 2 SO 4 electrolyte by the redox reaction of the PbSO 4 /PbO 2 electrode.
In short, a LiPoFe battery can take more charge faster than a lead acid battery can, so any charging system that will charge lead acid, will be like a trickle charger for the LiPoFe battery and will not harm the LiPoFe battery at all. As long as the lithium battery and lead acid charger are both rated for 12V.
However, to prolong the life of the battery and reduce the risk of deep discharge, it is advisable to set the LVC slightly higher.

AGM batteries, or Absorbent Glass Mat batteries, are a type of lead-acid battery that offer several advantages over traditional flooded lead-acid batteries. AGM batteries are sealed, maintenance-free, and have a longer lifespan than flooded batteries.
Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.
If you charge a sealed lead acid battery with a lower voltage than recommended, the battery may not fully recharge. This can result in reduced capacity and a shorter overall battery life.

$begingroup$ This rule of thumb is problematic as a 12V lead-acid battery is actually 6x2V cells in series. If a 2V cell of a particular size was able to be charged at, say 0.5A, six of them in series (six times the capacity) should also be charged at 0.5A. Voltage and power will need to be higher but the current should be identical.
