Charging an AGM battery requires a specific voltage to prevent overcharging or undercharging, which can damage the battery. In this article, we will discuss the AGM battery charging voltage chart and answer some frequently asked questions related to AGM battery charging.<\/p>\n<h2>AGM Battery Charging Voltage Chart<\/h2>\n<table>\n<thead>\n<tr>\n<th>Battery Type<\/th>\n<th>Charging Voltage<\/th>\n<th>Float Voltage<\/th>\n<th>Absorption Voltage<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>AGM<\/td>\n<td>14.2V<\/td>\n<td>13.6V<\/td>\n<td>14.4V<\/td>\n<\/tr>\n<tr>\n<td>GEL<\/td>\n<td>14.2V<\/td>\n<td>13.8V<\/td>\n<td>14.4V<\/td>\n<\/tr>\n<tr>\n<td>Flooded <a class=\"wpil_keyword_link\" title=\"Lead Acid\" href=\"https:\/\/batterytools.net\/lead-acid\/\" data-wpil-keyword-link=\"linked\">Lead Acid<\/a><\/td>\n<td>14.4V<\/td>\n<td>13.8V<\/td>\n<td>14.7V<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>What Voltage Should I Charge My AGM Battery?<\/h2>\n<p>The charging voltage for an <a href=\"https:\/\/batterytools.net\/super-start-agm-battery-everything-you-need-to-know\/\">AGM battery<\/a> depends on the battery&#8217;s state of charge (SoC). AGM batteries should be charged at a voltage between 14.4V to 14.8V at 77\u00b0F (25\u00b0C) until the battery reaches 100% SoC. This voltage range will ensure that the battery is fully charged without causing overcharging.<\/p>\n<h2>What Voltage Should a 12 Volt AGM Battery Read When Fully Charged?<\/h2>\n<p>When an <a href=\"https:\/\/batterytools.net\/everything-you-need-to-know-about-the-17tf-battery\/\">AGM battery<\/a> is fully charged, a 12-volt AGM battery should read between 12.8V to 13.0V. If the battery reads below 12.8V, the battery may be undercharged, and if the battery reads above 13.0V, the battery may be overcharged.<\/p>\n<h2>What Voltage Is 50% of an AGM Battery?<\/h2>\n<p>When the <a href=\"https:\/\/batterytools.net\/how-to-test-agm-batteries-a-comprehensive-guide\/\">AGM battery<\/a> is at 50% SoC, the battery voltage should read around 12.2V. It&#8217;s important to note that discharging an <a href=\"https:\/\/batterytools.net\/what-is-alpha-battery\/\">AGM battery<\/a> below 50% SoC can significantly reduce the battery&#8217;s lifespan.<\/p>\n<h2>What Is the Highest Charge Voltage for AGM Battery?<\/h2>\n<p>The highest charge voltage for an AGM battery should not exceed 15V. Charging the battery above 15V can cause the battery to overheat and reduce its lifespan. It&#8217;s important to use a battery charger that is specifically designed for AGM batteries to prevent overcharging.<\/p>\n<p>In conclusion, charging an AGM battery requires a specific voltage range to prevent overcharging or undercharging, which can damage the battery. By referring to the AGM battery charging voltage chart, you can ensure that your AGM battery is charged correctly, maximizing its lifespan and performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An AGM (Absorbent Glass Mat) battery is a sealed lead-acid battery that is maintenance-free and provides high-performance power.
