Make sure that the top of the battery is clean, dry and free of dirt and dirt. A dirty battery can be discharged through dirt on the top of the battery case. Check the terminals, screws, clamps and cables for broken, damaged, or loose connections. These must be clean, airtight and free of corrosion.
Some maintenance inspections, such as visual inspections, cannot be ignored and must be performed at least once a year. Obviously, a permanently connected monitor also increases the reliability of the battery system by a significant factor, since it is in service 24 hours a day, every day of the year. There are several factors that contribute to reducing the usefulness of a battery, including the number of discharges, depth of discharges, environmental conditions, and lack of regular maintenance. Consult the specification sheets or installation manuals for your batteries and chargers to find the specific values for each of the above settings.
Use a multimeter to monitor the charge of sealed lead-acid batteries based on voltage. Preventive maintenance maximizes operating time and extends battery life by eliminating problems before they occur. The reliability of the system must be monitored from many aspects, and one of them, no less important than others, is the monitoring and maintenance of the battery. No one can argue with the effectiveness of a capacity test, but unfortunately, due to its cost of execution, many users don't test the charge of their batteries.
A permanently connected battery monitor reduces the need for maintenance personnel to directly contact the high voltages present in most battery systems. Although batteries are sold with a variety of published lifespan, the fact is that most batteries have a lifespan of just three to five years. Since those early days, much more has been learned about why and how batteries fail, and with the introduction of VRLA batteries, a new series of battery problems has arisen. If batteries don't hold a charge even after a full charge cycle and equalization, they are likely to be defective, damaged, or have reached the end of their useful life and are starting to lose some capacity.
If a battery fails due to defect or deterioration, the best time to find out is during a preventive maintenance service, not during a power outage when critical loads could be compromised. The solar panel, battery bank and inverter must be the right size for the batteries to stay healthy. The following sections discuss, very briefly, what the IEEE standards recommend for maintenance and testing for both vented lead-acid battery systems and valve-regulated lead-acid battery systems. If it is not possible to use a maintenance charger, disconnect the vehicle's battery during storage to prevent the vehicle from discharging the battery.
For battery maintenance needs, contact your IBCI representative for options on scheduled maintenance programs that allow your fleet to operate efficiently and prolong battery life.
