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.
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.
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.
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.
