You can''t measure it by sticking an ohm-meter on a battery, but you can infer it by measuring the battery voltage while it''s under a load. You need a load appropriate for the battery voltage and current capability, so you might use an automotive incandescent bulb for a small 12V lead-acid battery, or an LED for a coin cell.
You need a fairly accurate multimeter to check whether a battery is fully charged. First charge the battery, and when you think it is fully charged, then take it out. Through a multimeter measure
Step 3: Identity the fully charged LED: The controller should have a specific LED that indicates a fully charged battery. This is often the green or blue LED. Step 4: Assess the battery charge level: If the fully charged LED is illuminated, the battery is considered fully charged. If not, the battery needs more charging.
A fully charged 12V lead-acid battery should read around 12.6V or higher. A reading below 12.4V indicates partial discharge, while below 12.0V suggests significant discharge or potential failure. For 6V batteries, the corresponding values would be half of those for 12V batteries (6.3V for full charge, 6.0V or lower for discharge).
By measuring the specific gravity, you can determine the state of charge of your battery and whether it is in good health. Preparing for the Test.

Checking an open-cell lead acid battery—that is, a lead acid battery with caps that can be opened to access the liquid inside—with a battery hydrometer is most accurate when the battery is fully charged. Closed-cell lead acid batteries without the access caps cannot be tested this way.
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.
To get a more accurate reading of a lead-acid battery's health, you can use a hydrometer. This tool measures the specific gravity of the electrolyte solution within the battery, which can give you a better idea of its state of charge and overall condition. Before using a hydrometer, it's important to make sure the battery is fully charged.
