Battery voltage between 13.6
For a lead-acid battery, it''s charging at 14.4V, but once fully charged, the resting voltage of the battery itself will drop back down to about ~12.7V. This depends on battery chemistry, and other factors like ambient temperature. Li has a more flat voltage curve, so voltage is not as good an indicator of charge as for lead-acid.

How does a lead-acid battery work?
Sulphuric acid is consumed and water is formed which reduces the specific gravity of electrolyte from 1.28 to 1.18. The terminal voltage of each battery cell falls to 1.8V. Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged.
How do you know if a lead-acid battery is fully charged?
One cannot deduce a state of charge of a lead-acid battery by its open circuit voltage, other than to distinguish between completely depleted and somewhat charged. In short, don't worry abouth the battery eye. If the battery performs well, leave it alone. If it doesn't - replace it.
How to charge a lead-acid battery?
While charging a lead-acid battery, the following points may be kept in mind: The source, by which battery is to be charged must be a DC source. The positive terminal of the battery charger is connected to the positive terminal of battery and negative to negative.
What happens when a battery is turned into a spongy lead?
The anode is transformed into lead peroxide (PbO 2) and cathode into the spongy lead (Pb). Water is consumed and sulphuric acid is formed which increases the specific gravity of electrolyte from 1.18 to 1.28. The terminal voltage of each battery cell increases to 2.2 to 2.5V.
Why does my battery turn green if I shake it?
The green color may be a matter of mixing the electrolyte. A fully charged battery turn green only when shaked. The level somewhat depends on the temperature, a hot battery may have somewhat higher level. Whatever the indicator shows, it is immersed in one cell, others (esp. in older battery) may be in another state.
Why does my car battery turn green?
May need topping up with deionized water (but the battery is likely marketed as maintenance-free and hard to open, so no topping up possible). The green color may be a matter of mixing the electrolyte. A fully charged battery turn green only when shaked. The level somewhat depends on the temperature, a hot battery may have somewhat higher level.
