When it is fully charged it should be at 12.9 volts. You should never allow your AGM to rest under 12.7 volts because just like every other lead acid battery when they discharge lead sulfate forms on the plates of the battery and if left in this condition it will weaken the battery (do not care what it is) long term. Alternators are not built to desulfate a battery either.</p></blockquote><p></p>
