Hi all (newbi). Punto easy with Brio pack 2014 1.4

I want to charge my battery. I have been told that I need to take off the stop start monitor lead, and that to do so I will loose all my stored memory on my milage in log A and log B. How do I charge the battery but retain all the accumalated data the log has stored. I would also like this info as the battery is now 4 years old and at some point will need renewing, and I would have the same problem retaining the memory data.
 
All cars with stop start have a different set up with the battery, usually they have an extended connector on the earth I think on the punto it has a second "dummy" negative connector away from the battery, this specifically allows you to charge the battery without disconnecting it and without putting the charger the earth of the battery as there is a condition monitor attached directly to the battery that mustn't be removed unless changing the battery.

It should be fine to charge the battery like this, still connected to the car, positive connected to the positive of the battery, negative on the dummy connector or on a metal part of the car chassis or engine.
you just mustn't connect the charger to the battery negative terminal where the monitor is.

I should add that if the stop start system is working and when working, doesn't restart the engine for 2 - 3 minutes then the battery is fine, so don't replace it. If its less than 2 minutes before the engine turns off then its getting tired but doesn't really need changing, anything less than a minute you could reconsider changing the battery. If stop start doesn't work at all, the battery condition is not good enough for stop start to work but if this doesn't bother you then there is still usually plenty of life in the battery.
A lot of people don't like stop start so if the system isn't working this suites them fine.

Thanks for the speedy reply. Ive just purchesed this car which has only 13000 on the clock, so not done a great deal of running. I was just wanting to boost it with a low charge over a weekend to ensure its up to scratch. As the stop start seems to have a mind of it's own when it comes to working. But have read some articles on this forum with regards to maintaining the battery in good charge, to aid the stop start as it's voltage compliant.

yep the battery monitor decides on the condition of the battery and feeds information to the car telling it when to turn off and when not to, If you have the manual it gives a lot of information on when it will and won't turn on and off.

However it's worth bearing in mind that the Fiat stop start system is a bit temperamental anyway so having a mind of its own can be normal.

Put the same battery on any other car from a different manufacturer and you would have trouble free stop starting for many miles to go, despite the fiat thinking the battery was weak.

I've just bought an EVO (basically the same car) a couple of weeks ago 2011 model with seemingly the original battery and I can sometimes manage as much as 30 seconds on the stop start before the car restarts. then other times it might only be 10 seconds or might not work at all and there appear to be no rhyme nor reason to it. :bang: I just put it down to italian engineering.
