Peugeot Boxer Vehicle battery.

Suspect that the subject battery in my 2012 Sussex Duo is not holding it's charge and may require changing. Heard so many do's and don't's on the procedures that need to be carried out when replacing the battery. Has anyone had experience doing this replacement. Thanks

Let Halfords do it I think they charge £15 (mind you, their batteries aren't the cheapest). Or the RAC will come to your home and do it, but again they are not cheap.

I would let someone else, maybe even a Peugeot dealer do it for several reasons
1 If the battery is simply disconnected then replaced, will the radio codes be lost (do you have the radio codes, btw)
2 To prevent that, a second battery can be connected to the main battery leads, to maintain a 12v supply whilst the dead battery is removed.

I don't really know, but would be worried about the ECU etc also. I do know that if the 12v is kept live, as above, this should not be a problem.

If, like mine, it is under the passengers feet (easy enough to access by removing the AS carpet, then the floor panel) it is a heavy beast to remove, hence I'd risk someone else's back!

Exactly my thinking.

Changed mine last week, straight forward battery out new battery in, no problems with codes on the radio or anything. All working as before.

Changed ours two week ago with no problems with radio. The BCM has a chip that holds all the info for us. 

Same here, this year and in previous years, I've disconnected the starter battery when in storage for the winter months with no ill effect. Hoping nothing changes this year when I reconnect.
