How Often Should You Apply An Equalizing Charge To The Battery? Different battery manufacturers recommend different intervals for when to apply an equalizing charge. The most common interval is monthly. But other manufacturers recommend once every 6 months, while others recommend every 10 or 12 cycles. So check with the battery manufacturer to see what they recommend and then follow that interval. Additionally, make sure you are adding water to the battery every month and every time you perform an equalizing charge. Is There More That Can Be Done To Maximize A Lead-Acid Battery’s Life? Performing these equalizing charges and adding water regularly to a flooded lead- acid battery will extend the life of the battery and help it perform optimally. But there’s a way you can extend the life of the battery even more and even bring a dead lead-acid battery back to life again… Our EZ Battery Reconditioning course shows you exactly how to do this step-by- step.
