Warning message on the 'control panel'

Good evening all
I changed the leisure battery this week and purchased a better quality than was in (see some posts in another thread).
All ok and it is charging well. when 240v is plugged in I get the 'plug symbol' ok and the gradient bars increase as it topping up
However the little warning triangle is flashing.
I disconnected the mains, still flashes, roof is down and in place, fridge is off water tanks empty so nothing else of note on the control panel.
BUT the little triangle is flashing

Does anyone have any ideas/experience of this and what may be wrong or I need to do??
Any advice as always gratefully received.

First off I’d just keep it plugged in overnight/12 hours and see if it goes off.

Lo and behold. a simple answer and Voila .. it all sorted.
Thanks
For this looking at a new leisure battery

link to the 110 amp/hour version at £139 (I think good value with 5 year warranty)

So, did you just swap out the leisure battery and no further programming or configuration was required?

Yes.
My lad had the van for a week at Glastonbury off grid and the battery was original (2019)
It was poorly to say the least.
So took the plunge and ordered new one
The side panel on the passenger seat is easy to gain access. The battery is a bit of a squeeze/jiggle
Pull the fuse for ancillary equipment etc and swap out the battery +ve has an extension lead on and -ve goes straying on .
very fiddly to get back in but hooked up locked up and started ok.
Checked the roof, the fridge and water tank
All worked ok

Popped on charge last night to top up
All good
Yes not cheap but peace of mind and flexibility for a few years

Mine will be on its original, not sure it’s showing much evidence of degradation. It would be wise however I reckon to so the same as you this year.

Tbf I don’t do a lot of off grid as use more hook up sites but I thought with its being at 10.5/11 it was poor and I don’t want to get caught out
Next step os fitting and awning this month as an upgrade
