Lead–acid batteries that have removable caps for adding water, like vented lead–acid (VLA) batteries, require low maintenance to keep the correct level of electrolytes and the optimum battery performance. VLA batteries are preferred over VRLA batteries since the former have a lifespan from 15 to 20 years, and are often substituted due to their age instead of failure
