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.
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.
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.
The liquid-filled lead acid batteries used in automobiles and a range of other products have many great qualities, but are also known to “go bad” with little warning. 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.
This Lead Acid battery tester works on all automotive 12V lead-acid batteries. Suitable for testing various battery types including ordinary lead-acid battery, AGM flat plate battery, AGM spiral battery, and GEL battery, etc. It quickly, easily, and accurately measures the Alternator’s charging and Starter’s cranking conditions.

How to test a lead-acid battery
Well what you need to learn first is the voltage range in which a lead-acid battery should be operating. A healthy, fully charged battery should be sitting at 12.7 – 12.8 volts. And at the other end of the scale, a lead-acid battery is considered fully discharged when it reaches 12.0 volts. Finally, to remain healthy, a lead-acid battery should be at least above 12.5volts at all times.
