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.
CALCULATED VS. ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
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.
Estimated short circuit values can vary widely depending upon the test method and measurement technique. Multi-stepped discharge test methods that use a large span in current and voltage provide the best accuracy in estimating battery short circuit current and resistance.
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.

In IEC896-2 "Stationary Lead-Acid Batteries, Part 2: Valve Regulated Types", the estimated short circuit current is obtained by discharging a battery at 4 times and 20 times its rated 10 hour discharge current (I10 at 25oC to 1.75 volts per cell). At the 4X rate, the battery voltage is measured at 20 seconds.
Diagnosing faults in a lead-acid battery can be done by performing tests such as the open circuit voltage test, the load test, and the internal resistance test. If the battery fails any of these tests, it may need to be replaced. Other signs of a faulty battery include slow cranking, dimming headlights, and a battery that is hot to the touch.
