2014 X250 Ducato 2.3 130 – Replacing Starter Battery With Start/Stop Fitted

Looking for some advice on changing the starter battery on a van with start/stop fitted.

My starter battery is showing signs of failure and won’t go more than two days before being unable to start the van, so time for a new battery but I need to know the following:

1. will the new battery need coding to my vehicle and if so can I do this with something like MES or is it a dealer job?

2. when changing the battery do I need to supply constant power to the vehicle or can I just detach everything and swap the batteries?

TIA.

Not Ducato specific, but generally speaking:


I wouldn't try to keep power to the vehicle, spikes on modern vehicles can cause damage to ECUs when you're disconnecting and connecting the battery. Better IMO to let it power down completely.


Batteries don't normally need coding to the vehicle, but with start/stop systems there is usually a battery monitoring sensor in the system. There are functions in various diagnostic applications to reset these by programming in the parameters of the new battery, but generally if you remove the ignition key and leave the vehicle locked with all doors shut for several hours after replacing the battery the system will reset itself. The programming is so that garages can hand customers their cars back fully working when they don't want them sitting around the premises for another 6-8 hours. All that is likely to happen without it is that the start/stop system might be disabled until it has had chance to recalibrate itself.

Thanks for the reply. I've been asking around about this whilst getting prices for a new AGM battery and am getting mixed info.

Some are saying that the replacement needs coding and if I change the battery without doing so the van will only charge the new battery based on the stats recorded for the knackered one and therefore the battery won't last as long.

Fiat don't seem to want to give any info out but are happy to talk about the £440 they want for a new battery.

Thought I might need a new battery on the Fabia. Original is coded.
OE battery very expensive, best price I could find was a Yuasa. No coding label.
Yuasa support said if wished to code, just increment the old battery number by one.

I guess that'd work for most makes.

Sorry, had no internet access for the last few days. If you replace the original battery with one of the same type and capacity, the BMS will sort itself out after the van has been left sitting and locked up for a few hours, preferably overnight. If you change the capacity of the battery, the new battery details should be programmed in. Not sure if MES can do it, I don't have stop/start on the van so never looked, but there are several fairly inexpensive diagnostic tools around now that include functions such as battery reset and steering angle reset along with service and oil change resets etc.

Thanks guys.

@RS3100; Fingers crossed the van will just sort itself overnight as you say.

One thing I noticed is it appears that my van already has a larger 020 type battery fitted from the factory which could be a bonus as I was looking at that over the standard 019 size fitted to most ducatos. I haven't pulled the battery yet but have measured it at 393mm which is definitely longer than the 019 which are around 353mm. Hopefully the van will be 020 ready so no faffing around with a new diagnostic tool (MES doesn't seem to have a feature for battery reset/coding).

Only thing now is to find a Varta H15 020 or similar for a decent price.

Don't rule out Halfords battery's .... I fit lots of them to various machines now and have not had a warranty issue with one yet .
I have been told the Halfords own brand batterys are Yuasa .
Halfords also sell premium Yuasa batterys and do stop / start ones .
With a Halfords trade card their batterys are cheaper than I can buy elsewhere of a similar quality .
My old Willys Jeep has had the same pair of cheap Halfords battery's for the last 7 years and starts every time even after a 6 month lay up .
