The starter battery is not usually charged from motorhome charger off EHU. It does show your starter battery is ok though. Have you checked charger is putting over 13volts into leisure battery while plugged into mains? If it is that just leaves leisure battery & after 11yrs you might as well replace it.
If you find you starter battery sounds a bit tired as well then you could replace both then you know you will have reliability.

Hi
The link might be useful http://www.campingandcaravanningclub.co.uk/GetAsset.aspx?id=fAAxADMANQAxADAAfAB8AFQAcgB1AGUAfAB8ADAAfAA1
Another thought. My charger has a switch the directs the charger to either leisure or vehicle battery.
The switch is at the back of a cupboard and can be knocked accidently to the vehicle battery position.

Thanks for the advice Leisure battery showing 8.7 volts starter battery 14.5 volts thats after 2 days on 240 supply both batteries nearly 11 years old
Unless the starter battery was removed from the charger for a while, 14.5 volts indicates it is still being charged. 8.5 volts for the leisure battery shows it is a gonner. But, given the mystery of the starter battery voltage, are you sure the charger was charging the leisure battery and not the starter battery.
If the leisure battery was not being charged, perhaps because a switch was in the wrong position, the batteruy may have failed due to not being charged. You really need to make sure it was being charged otherwise the new battery will also fail.

Not all motorhome EHU electrics are set up to charge starter battery as well. Without more details one can only give general advice but 11yr old batteries have done well to last that long.
