Adjust your specific gravity reading based on the liquid’s temperature. The specific gravity chart for lead acid batteries assumes a liquid temperature of 80 °F (27 °C). That said, the liquid in your battery probably isn’t at this ideal temperature.
The electrolyte solution in a lead-acid battery expands when warm and contracts when cold. This affects the density and specific gravity of the electrolyte. Hydrometers measure the specific gravity of the electrolyte to determine the state of charge. And changes in temperature can alter our results.
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.
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.
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.
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.

Battery Temperature Monitoring System
A simple manual battery temperature monitoring system would be to have someone physically check the battery string once or twice a week. An IR temperature gun can do this, and you can record the data in a spreadsheet. Remember you are looking for not more than a 3°C difference between the battery and ambient temperature.

How Does Temperature Affect Battery Life?
Both of these factors are affected by temperature. For lead-acid batteries, a higher temperature can increase the rate of sulfation, which can reduce the battery''s cycle life. Sealed batteries, on the other hand, are less affected by temperature and can last longer than flooded lead-acid batteries.
