A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
If it's fake, are they playing with our minds? The most accurate way to measure lead-acid battery SOC (State Of Charge) is read the specific gravity with a hydrometer. When the battery is fully charged the electrolyte has the maximum amount of sulfuric acid so the specific gravity is highest.
Fortunately, you can easily do a basic health checkup on any type of lead acid battery by hooking it up to a simple-to-use digital voltmeter. If you have an open-cell battery that lets you access the liquid inside, you can do a more rigorous checkup with a battery hydrometer. Charge the battery fully, then let it rest for 4 hours.
Charge the battery fully at least 8 hours before testing it. Lead acid batteries recharge in various manners based on their function and manner of installation. For a lead acid vehicle battery, drive the vehicle around for at least 20 minutes. For a lead acid battery connected to solar panels, let the battery charge fully on a sunny day.

Lead acid batteries are kind of a special case among battery chemistries that the open circuit voltage is a reasonable measure of the charge of the battery. For this you just need a voltmeter. See this question for what voltage levels correspond to what charge level of a lead acid battery.
