My HSE Manual is coming up for its 4th birthday and the battery is struggling a bit so thought I'd replace it.

If I change myself am I likely to run into probems with all the electronic stuff?

I'm aware that garages may connect a power supply whilst changing to avoid problems.....would like to hear if anyone changed themselves without a power souce.

Cheers

No problem doing it yourself. You'll have to reset the clock on the CD and the service indicator. A simple post on here about how to do it.

you may need to reset the windows, easy enough apart from that no probs At work

No, never had to reset the windows and I've disconnected the battery about 8-10 times.

Did mine a couple of months back now. Easiest way around any issues regarding resetting stuff is to plug a memory saver into the 12v socket. I dd that and all bar the windows, everything was saved.

Thanks guys. Took the risk and used no external power supply.
Just Clock and Windows needed re-setting, as advised.
