Hi I recently bought a Fiat Punto evo GP and I noted after a few weeks of driving that I never had the start/stop function work.
I read on theses forums that there are numerous parameters that the car engine management system needs to tick before it activates the system So I persevered, however I just found out that the battery is only 43ah.... No wonder!!!!!!!!!!!!!!

Its the wrong battery, I have been suckered (private sale), oh well!!

So I have bought a battery EXIDE EL700 110 ECM (70ah) from JCB Just car Batteries in Preston

I mentioned that I was a Fiat Forum member and they gave me 7.5% off, result, chuffed!! Fiat wanted £145!!!

Just realised this is the same company I've recently brought a Bosch Silver Battery from through eBay.

Highly recomended by myself also

And me.....

Did you charge the battery before fitting it?

Yep, and tested it before and even my cheap tester with 4 lights said it needed it.

wasnt talking to you

its imperative for the correct function of the start stop for it to "learn" from a fully charged battery (once fully charged it should be left for 1 to 2 hours to allow any surface charge to dissipate)

Hi Guys,

Well yep!, I charged it over night and will install Saturday. Its amazing how much it needed. Thanks for the info about the car needs to learn from a full charged battery.
Its amazing what you learn, I wonder what the fuel savng will be once the stop/start is fully operational!

when you take the old battery off leave the car for an hour this should clear the ecu/ body computer/ ss system so it starts with a fresh sheet so to speak

you will probably find the car behaves strangely for a few miles till it learns and settles down
