Changing battery on 406

What problems am I likely to encounter when changing my battery?
I appreciate that I will have to re-enter my radio code but is there
anything else?
Anyone got a Haynes 406 manual for sale it is a R Reg. Thanks

 

Have a look on eBay for a second hand manual. Got mine for half the shop
price including postage.

You may not have to recode the radio. According to the more knowledgeable
people on this group it is linked somehow to the ECU which will recognise it
when the new battery is connected.

 

Hi,

It may also depend on car's manufacturing date, it's true you haven't to
recode the radio if it's a muxed car (2001?).

 

R reg will require the radio code and clock reset but that's it.

 

If you can get theAA to do it they have a "Gizmo" that they plug in the
ciggy lighter that keeps the power.

 

Presumably 8 AA cells connected in series ?

 

Or you could buy your own - Ebay is usually a good place to look...

I suppose, if you can get hold of a cigarette lighter plug (my electric pump
comes with one), an ordinary battery charger would provide power to maintain
the codes.

 

Halford's do one as I got one myself a couple of years ago. It consists of
a
mains plug-in charger, like a mobile phone charger, with a cigar lighter
fitting. That is sufficient to keep the ECU and radio codes whilst you
change the battery.

 

Or use jumper leads from another vehicle during the changeover. Wish
I'd thought of that before the two battery changes I've made!
