Without seeing the battery spec I would have thought that a resting voltage of 12.8V was normal.

Voltage is not a very good indicator of charge for example 12.8V might be 100%, 12.6V might be 80% and 12.5V might be less than 50%.

I assume you measured it on the terminals, but remember that there will still be some current flowing with the car unlocked and bonnet up and this will give you a slightly lower reading. All of this is slightly different to a battery out of the box with nothing connected.

I was disappointed in the fact that the battery was not instantly compatible with the charging system after the car booted up.
After driving on Monday and Yesterday the battery resting voltage this afternoon is 12.87V.
While this is quite good, it is only 0.07V above the voltage out of the cardboard box, after spending 3 weeks in transit from Melbourne.
I have asked Suzuki to look into how to make the charging system recognise the EFB Battery and charge it appropriately. More later..

Thank you all for the response and comments to the above post.

During the week I had a chat with a retired Suzuki Service Manager, he is also and a Jimny owner/driver and mechanic. His expectations for a traditional lead/acid Battery is a resting voltage of 12.8V with a healthy alternator/charging system. However for the new EFB Battery he said I should be seeing 13.0-13.2V under the same conditions.

Today, Saturday, my weekly Voltage check:
New EFB Battery in the Car: 12.80V
Original Battery on the bench: 12.76V

The Voltage in the car is now what I would expect after each drive, a net loss of 0.1-0.2V.

Today I have started to rust proof the underneath, starting with the front. By 'me' I mean I mainly watched his majesty at work but the bits I did I managed to not cock up (like last time). Looks better with black wheel arches

Today I have fixed mr roof and had to put the standard antenna base back on. This was the result of not realising the garage door was fully up when I put her to bed last night.
I will have to just leave the whip off for now, which won't be a problem now I am not commuting to work.
