Battery change

[fisherman]

Hi all
I have a Peugeot RCZ 2013 1.6 156 hp petrol. Unfortunately it’s time for a new battery it looks a bit fiddly, but does anybody know if I will experience any problems when replacing the battery i.e. will I have to reset anything windows, alarm Radio code etc. I was considering using jump leads from another car to keep the power going in when replacing the battery. any help and advice would be greatly appreciated.

regards fisherman

Turn off engine, open the bonnet, let the car sit for >3 minutes for it to go to sleep. Then do the change. Wait a minute after connecting the new battery before opening the car.
The most important bit is the wait time for all modules to go to sleep. This also comprises a so called BSI reset ( minus the battery change).

I have disconnected and reconnected the battery many times and the only thing I have to do afterwards is set date and time on the clock.

But I have always made sure to have a window down in case it decides to close.

Hi there thanks for the information, I’m not sure what you meant though, about leaving one of the windows down in case it decides to close only I’ve read some were that the windows sometimes need resetting when the battery has been disconnected.

Hi there thanks for the information the old battery is flat so the car won’t start any way, so am I to assume all the modules will be well into a sleep mode as I won’t be able to start it up switch it off and then leave it for 3 minutes plus before changing the battery , also could you explain what a BSI reset is and the relevance of the (minus the battery change).

You don’t need to start it, just take the key out of the ignition, shut the door and wait for three minutes. Then all modules are asleep.
A BSI reset is a reset of the main BSI module, sometimes this helps when you have some weird (electrical) problem. You do this by disconnecting the battery (using the procedure above), waiting for a few minutes, and then reconnecting it again.

Hi there and thank you for your reply, just to clarify then, even though the car has not been used due to its flat battery which incidentally I have tried to charge but remains at 9.5 V hence the reason for replacing the battery so there is not enough charge in it to turn the engine over, but still enough power to keep the alarm system and the door locks working. So I still have to put the key in the ignition, then switch the ignition on, But do not try to start it then shut the door and wait three minutes, at what point during this procedure then should I open the bonnet for access to the Battery. Someone has also mentioned on this thread that I should leave one of the windows down or does this not matter All help is greatly appreciated

No, just take the key out, open the bonnet, close the door and wait three minutes. It might not even matter if you do not close the door, as long as you don’t close it within these three minutes, because then you have to wait three minutes after that.

When the car is off, modules go to sleep after three minutes, but things like opening doors/using keyfob will wake some modules again. And you want to disconnect the battery when all are asleep.

I changed mine roughly 3 months ago and didn’t do any of the 3min rule and had no problems since….
The circuit board thingy on the edge of the battery was a sod to get off but bit of persistent wedging up with screwdriver got it loose …..

The rule of thumb is disconnect the old one remove from car & refit the new one as already stated the clock will got go to default setting but can be reset without issues what to avoid is intermittent disconnecting & reconnecting for any reasons as this can open a can of worms on modern cars

Oddly hdi and did and now now power to the starter . Doors open and lock and dash lights but click when you turn the key

Check battery connections 1st you could then try a battery management reset by disconnecting & reconnecting the live lead & make sure the terminals are tight if it still persists check the battery control module
