Tech Note | The Proper Charging of Stationary Lead-Acid
There are basically three methods of charging lead-acid batteries: Constant current charging means that the battery charger output voltage is varied so that it supplies a relatively uniform current regardless of the battery state of charge. This is appropriate for a battery used in a cycling application such as a traction battery and requires

How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.

Can a lead acid battery be charged at a full charge?
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
What happens if a lead acid battery is overcharged?
Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: Reduced Battery Life: Exaggerated use increases internal resistance, reducing the number of cycles performed.
Does a lead acid battery change resistance compared to state of charge?
Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I'm also assuming a constant charging voltage from an alternator.
How long does a lead acid battery take to charge?
Ideally you can configure the cut-off coltage, such as with the depicted unit. So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted.
Should you charge a lead-acid battery with a saturated charge?
We’ve put together a list of all the dos and don’ts to bear in mind when charging and using lead-acid batteries. Apply a saturated charge to prevent sulfation taking place. With this type of battery, you can keep the battery on charge as long as you have the correct float voltage.
How often should a lead acid battery be charged?
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.
