Hi all, last night I popped the battery on charge as to give it a top up charge ready for the weekend. today However the reading from the multimeter reads 12.90v Is this overcharged or full as the battery is now disconnected as I didnt want to damage the battery. I've heard that a full battery is 12.69 or around that mark

If you measured the voltage directly you disconnected the charger, then it will drop some after a couple of hours, which is normal.
12.9 is a very good reding if the measurement was taken a couple of hours after charging.

Yes it fluctuated around 12.90 and dropped to 12.88 and has stayed around that mark
