Thanks once again for everyone's advice. I have ordered a new 12V battery and plan to fit it this weekend.

I had a read through the guide on Go Green Autos, and the only thing now on my mind is the Radio Security Code. Is there a way to verify this before you get started? I have the car's Handbook, and on the last page there is a bit that looks like there should be a sticker or something giving you the code, but it looks to me like it's generic/no sticker in place. It says 1234 and that is the same as I found when I downloaded a PDF version of the Handbook (which would not be specific to my vehicle).

A previous owner has cryptically written a 4 digit number on the front cover of the Warranty And Maintenance Record booklet, but with no clarification of what that number refers to. I suppose I could take a chance and assume that is what I need, but it would be great if there was a way to verify this before I disconnect anything?

I'm not aware of any way to verify the code without actually having to use it after disconnecting the battery, unfortunately. So you're probably going to have to chance that the hand written 4 digit code is the correct code as it's unlikely to be 1234...

A genuine code will only contain digits 1-6 as there are only six buttons beside the display to enter the code, so if you see 7-9 or 0 in the code it won't be the correct code!

The code can be recovered with the dealer diagnostic tool Diagbox/Lexia 3. When I got my Ion the radio was locked out for exactly this reason (disconnected battery and lost code) and the seller (an Indy garage without the dealer diagnostic tool) wasn't able to get the radio working so knocked £50 off the car.

I took it home and plugged in my own grey market Diagbox/Lexia 3 diagnostic tool that I'd bought a few years earlier and in 5 minutes had it unlocked and also retrieved the code so that I can now re-enter the code without the diagnostic tool if I disconnect the battery.

Peugeot of course are able to recover the code as well but they may charge you to do that - perhaps phone them up and ask in advance what they might charge if the code written down doesn't work ?

If you can't find the code and don't want to take a chance, you could hook up a little 1 amp battery maintainer/charger to the positive cable and a ground before you disconnect your cables from your current battery. That would act to 'keep alive' the circuitry in the car while you swap out the battery for the new one. You shouldn't have any problem with the radio requiring it's code be reinserted that way

It is not a problem with a fairly simple battery swap, take old out and put new in, at least for the Nav unit versions, they seem to have plenty of backup time.

i have disconnected the 12V for extended periods from several days to weeks, and never had an issue or need to enter any code on 2 cars with Nav units.

I-Miev and Ion head units are completely different Kiev.

If you disconnect the battery on an Ion/C-zero for even less than a minute it will require the security code to be re-entered. I know because I’ve done it many times.

The easiest solution might be to carefully connect another small 12v battery with alligator clips during the changeover like a small 12v gel cell.

The problem with using a battery charger as suggested earlier up is that a modern cpu controlled one will not operate if it does not continuously detect a battery, and many old dumb chargers which would do not have voltage regulation so may subject the car to more than 15 volts with the battery missing and unable to act as a ballast so I would not risk the charger approach.

All sorted, thanks everyone! My dad came and helped me fit the new battery, we used some jumper leads to keep either the old or the new battery connected to the car throughout so didn't need a radio code thankfully.

I have since been enjoying a luxuriously warm bum, and will appreciate not having to worry about the health of the 12V battery for the next few years :)

Congrats! Just remember to connect a smart 'float' charger to the 12v battery whenever you leave the car unused for a week or more.
