The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries. This range indicates that the battery is fully charged and in good condition. If the specific gravity is below 1.225, the battery is discharged and needs to be charged.
29 Οκτ 2023 · The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries, which indicates that the battery is fully charged and in good condition. Understanding battery specific gravity is crucial for maintaining the longevity and performance of your batteries.
25 Νοε 2010 · Specific gravity and charge of lead acid batteries - temperature and efficiency.
22 Οκτ 2021 · As the battery discharges, the sulfur ions in the sulfuric acid solution react with lead to form lead sulfides and water. As the water levels in the electrolyte increases, the specific gravity of the acid drops. During charging, the electrical current introduced in the battery causes the lead sulfide to dissociate into sulfur ions and lead.
Specific gravity is defined as the ratio comparing the weight of any liquid to the weight of an equal volume of water. The specific gravity of pure water is 1.000. Lead-acid batteries use an electrolyte which contains sulfuric acid.
30 Αυγ 2024 · The most popular hydrometer on amzn is used for measuring the specific gravity of a lead acid battery with access to its chemistry. I put together the following battery state-of-charge chart which indicates the state-of-charge (percent) as it relates to battery voltage or specific gravity.
For temperature adjustments, get a specific gravity reading and adjust to temperature by adding .004 for every 10° F above 80° F and subtracting .004 for every 10° F below 80° F. A fully charged lead acid battery used in todays car has a specific gravity of 1.265 fully charged. Use this handy guide to perform this test using a battery hydrometer.
