Suppose on were using an inverter with 90% efficiency, (Unlikely, but for the sake of argument) And a battery with 100 amp hours available. Now, build a BIG battery, giving 10 times the amperage... It''s obvious, that the bigger one can run the same inverter for as much as 10 times as long at the same voltage and amperage... All else considered ...
Characteristic of the open (or vented) lead acid battery is that the small amounts of hydrogen and oxygen produced at the electrodes during battery operation can be vented to the atmosphere through small holes at the top of the battery.
Lead-acid batteries, which are waiting for installation, should be stored in a dry and cool atmosphere. The long time storage at high temperature will have a detrimental effect on life as the corrosion of the lead electrodes is accelerated at elevated temperatures.
Opposite of state of charge. (100% minus state of charge in %). A fully discharged battery has reached 100% depth of discharge. Maximum 80% depth of discharge is recommended to give a reasonable lifetime of a lead acid battery. A maximum 50% design DOD is recommended in a PV system due to the often very slow and irregular recharge.
If you connect a voltmeter over the terminals of a 6-cell monoblock lead-acid battery at rest, it will show about 12-13 volts. (During charge up to 15 volts may be acceptable and during very rapid discharge down to 9 volts can be normal). The theoretical voltage of a lead-acid battery cell depends on the chemical reactions inside it.
The steps used in charging of an open or vented lead acid battery are named: main charge, used for charging the battery up to a voltage level when gassing starts and the voltage rises. (The voltage limit is 2.39 V at 25°C and 2.33 V at 40°C). top-up charge, to reach the 100 % state of charge from a level of 90 - 95 %.
In lead-acid batteries, there are three active components, the positive electrode active material, the negative electrode active material and the electrolyte. One of these substances will limit the capacity. When one of the active substances is consumed the battery voltage will collapse and the battery is discharged.

So maybe the question is really, "Do you need a DC-DC charger between the alternator/lead acid starter and the LifePo4 house battery" in which case I think the answer is yes. One reason, like said above, is that the DC-DC charger would output the appropriate charge profile to the LifePo4 as the alternator would already handle the Lead Acid.

While the chemistry of lead acid batteries is quite simple, writing out all the chemical ...
Battery voltage, or state of charge (SOC), of a lead-acid battery can be estimated by measuring the open (no load) battery terminal voltage using a digital voltmeter. Prior to measuring, the battery must have rested for 4 to 8 hours after charge or discharge and resided at a steady room temperature. With these conditions met, voltage ...
