Leisure battery

Can anyone tell me the amp hour of my 2017 warwick Xi leisure battery will not fully charge so I am thinking needs replacing do i just turn off main switch before changing

It should be stated in the Owner's Manual (in the Fitted Equipment section) but, as with a lot of things that A/S fit, you'll only know for certain by looking at the one that's there - the specification will be marked on it.

If not written on it, measure it's 3 dimensions, go to TAYNA website. Select leisure batteries and see what is nearest but marginally smaller.
Alternatively, measure the space it fits in and get the biggest capacity one that'll fit in the space.

My 2010 Duo has a 105amp but mine is under drivers seat so is limited by size.

If I increase from 95ah to 110ah do I have to reset panel charge rate

Sorry can't help on that, my panel/system is older and simpler (i.e. nothing I can change).

EC500 PSU? The "hidden " menu has a battery size option to change.

To access the advanced settings, on the home screen (the one with the company / brand logo),
press and hold the up and down arrows together. Continue holding these buttons until the
screen changes.
To scroll through the various settings use the up and down buttons. To change a setting press
the select button (left arrow).
