Customer ServiceMaintenance-Free: Unlike traditional lead-acid batteries, sealed lead acid batteries are designed to be maintenance-free, eliminating the need for regular electrolyte checks and water refills. Sealed Construction: The sealed design of these batteries prevents electrolyte leakage, allowing for safe operation in various orientations without the risk of spills or gas
Customer ServiceSealed lead-acid batteries, also known as valve-regulated lead-acid (VRLA) batteries, are maintenance-free and do not require regular topping up of electrolyte levels. They are sealed with a valve that allows the release of gases during charging and discharging. Sealed lead-acid batteries come in two types: Absorbed Glass Mat (AGM) and Gel batteries.
Customer ServiceIn the context of lead-acid batteries, specific gravity is a measure of the electrolyte''s density compared to water. In practical terms, the specific gravity of a battery''s electrolyte provides insights into its state of charge. As a battery discharges, the specific gravity decreases, and as it charges, the specific gravity increases.
Customer ServiceTo 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.
Customer ServiceTypically, a reading between 1.265 and 1.299 for a fully charged battery is considered healthy. However, keep in mind that different battery types and sizes may have slightly different optimal ranges. In conclusion, checking hydrometer readings is an essential part of maintaining the health of your lead-acid battery. By understanding what these

Customer ServiceAs the first type of rechargeable battery, lead–acid batteries have been used as small–medium scale energy storage in various industries [1], [2]. Compared to other batteries, they are robust in operation, more environmentally sustainable (i.e., highly recyclable), require simpler control, and are resource efficient [3], [4], [5] .
Customer ServiceSafety Precautions for Lead-Acid Battery Testing. When testing lead-acid batteries, safety must be a priority. These batteries contain corrosive sulfuric acid and produce explosive gases during charging and discharging. Always wear appropriate protective equipment, including gloves and goggles, and ensure that the testing area is well-ventilated.
Customer ServiceFortunately, 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.
Customer ServiceLoad 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.
Monitoring this parameter is crucial for understanding the overall health and performance of lead-acid batteries. The specific gravity of battery electrolytes is typically measured using a hydrometer, a simple device that allows for the assessment of a liquid’s density.
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.
Each battery chemistry delivers its own unique discharge signature. While voltage-based SoC works reasonably well for a lead acid battery that has rested, the flat discharge curve of nickel- and lithium-based batteries renders the voltage method impracticable.
