This is typically a consequence of prolonged discharges or incorrect recharges. As a result, the battery loses capacity and performance, significantly shortening its lifespan and increasing the likelihood of premature failure.  <\/p>\n<p style=\"color: #ffffff;text-align: justify\">Preventing sulfation not only helps extend battery life but also ensures more reliable performance.<strong><br \/>\n<\/strong><\/p>\n<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d560359 elementor-widget elementor-widget-wp-widget-text\" data-id=\"d560359\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wp-widget-text.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h5>1 &#8211; SUITABLE ENVIRONMENT<\/h5>\t\t\t<div class=\"textwidget\"><p style=\"text-align: justify\">\nBefore measuring, ensure that no devices are connected to the battery and no external sources are supplying power.
