If the voltage reading is lower than the manufacturer’s specifications, the battery may be weak and need to be replaced. If the voltage reading is within the manufacturer’s specifications, the battery is likely in good condition. To get a more accurate reading of a lead-acid battery’s health, you can use a hydrometer.
Load testing is one of the most accurate ways to check the health of a lead-acid battery. It measures the battery’s ability to deliver current under a load. This test can help determine if the battery is capable of supplying the required current for a particular application. To perform a load test, you will need a load tester.
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.
Lead-acid batteries are prone to something called sulfation that affects the lead plates inside the battery. It's not like corrosion that can be cleaned away. An equalization charge is something that should be done periodically to reverse the effects of sulfation in a flooded lead acid battery.
In lead-acid batteries, this is a mixture of distilled water (pure H₂O) and sulfuric acid (H₂SO₄). Sulfuric acid can be dangerous because it is odorless, colorless and strongly acidic so take precautions when working around batteries, especially if the electrolyte is leaking. What is Specific Gravity?
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.
