Bourton leisure battery

I've searched on here for advice on how to remove the leisure battery from under the passenger seat but can't find anything.  I have been told that you have to remove the seat!  Is that so?  Is that easy?

This is a common problem with most makes of chassis.  The seats are normally (on Ford & Sevel Based vans) held in place with Torx type bolts and are generally accessible but the seats can be quite heavy. Otherwise its not a difficult job.

Hi
  On my 2008 Surrey which is the same as the Bourton except it has 4 seat belts the front seats are held down by bolts with allen key heads, this may have changed with newer models,they are done up very tightly and you will need socket based allen keys or torx sockets to undo them. yes the seat is very heavy you will need to slide the seat backwards and forwards to access the bolts in each corner.

Alan

Thank you all.  This is very helpful and for the picture Peter.  I'll get out there at the weekend and have look.  I will report back.

I rang Autosleeper for advice on changing battery. I was told to remove seat..”a 5 minute job I was told” Huh! Hex nuts I was told.
3 weeks later I am still trying to get the nuts off.
You cannot  get a spanner or socket set in the u shaped bar that acts as the slider for the seat. I bought hex nut drivers from the web because ToolStore,Screwfix,Halfords and BandQ do not sell 17mm drivers. The nuts are on so tight that my Makita will not budge them with the new drivers. On very close inspection I find they are Nyloc nuts - that is a nut with a nylon collar that locks the nut onto the bolt when tightened.
The web says I should get a butane burner and melt the nylon thus allowing the nut to be released.
I think I’ll give that a miss on my 60K Bourton

Please see photos of my set up on the 2015 Bourton...they illustrate what I mean
I may be totally off beam.. but Autosleeper told me to remove the nuts and lift up the seat to get to battery below

When I had to remove the batteries on our Rienza I found it easier to tip the seat side ways resting it on the passenger seat. This just gave me room to lift both batteries out. A piece of wood acted as a prop to prevent it falling on me. Good luck with the mounting bolts, yours sound different to the Ford.

Looking at Peter's photos I wonder if you are trying to remove the right bolts. I can see some pretty inaccessible nyloc nuts in the slides which secure the seat to the top of the turntable. Removing those the turntable in place still blocking access to the battery. You need to remove the four bolts that hold the turntable to the box under the seat - and in Peter's photo he has turned the seat for access to those Allen key headed bolts. As with my Nuevo, the slides are on top of the turntable and not below. Where are your slides, above or below the turntable?

Thankyou all for you advice. I have now swivelled the seat  and extracted the hex nuts with some degree of force. Battery is out and will be replaced shortly.
It would be very helpful if the advice I have received from the Forum members that took the time to help was included in the  AS manual.
