Lead acid, 12 volt, batteries will settle to 12.7 - 12.8 when fully charged with no loads and no charging source. All is well with the voltage you're seeing. 13.6 ish is the float voltage the controller holds the battery at when done charging.
Several factors can influence the voltage levels of a fully charged 12V battery: Battery Type: Different types of batteries (lead-acid, AGM, lithium-ion) have varying optimal voltage levels. Temperature: Extreme temperatures can affect the chemical reactions within the battery, altering its voltage output.
This happens when the voltage reads around 12.6-12.8 volts. At this level, the battery has its maximum energy stored for powering devices. Voltage measures how strongly the electrons are pushed from the battery. More voltage = more power available. Less voltage = low battery charge.
