Technical  4 dash warning lights appeared.

A resting voltage of around 12.5 is not ‘good’ for stop-start battery. Replace it as soon as you feel you can as other errors will follow otherwise…. The car will start with much lower resting voltage than that, but the monitoring systems around the car will start to show errors if it drops any lower at start up.

As soon as my wife stops buying Fiat branded "fripperies" I can buy a battery :)

Why do you need disco lights that flash in time to the radio :rolleyes:

It will surely last. And wouldn't need replacing, IR 5.64 is very good. You could just put it on the charger a little bit.
Just... is that battery classic flooded lead-acid? If so, that is not quite ok for start/stop systems. For that you need an AGM type or at least an EFB one.
Also, charging voltage 14.36 very good. Is the alternator traditional or smart?

This is the battery fitted, can you tell what type it is from the pic?, I just tested it as a normal lead acid, but do have other options on the tester.

I would say it is EFB, from that pic. Maybe you can find that marked specifically. Check under the stripe, I think there it says "enhanced flooded...". Marking can be on other sides, too.
IR for EFB goes like this (a little different than classic lead-acid)
Excellent / new 3 - 5 mΩ
Good / healthy 5 - 7 mΩ
Worn 7 - 10 mΩ
Bad / failure >10 - 12 mΩ.
But you measure it wrongfully as normal lead acid so you should test it again choosing its correct type, EFB.
Also, the state of terminal and its connector shown in pic is not at its best. There is some surface corrosion and oxidation which increases resistance at the connection and causes voltage drop under load and poor charging. You can clean that. Try and find the production date code, too.
 
Replaced the start stop battery on our hybrid recently at 4 3/4 years old. The car had stood nearly unused for 3 months jan/feb/march so that didnt help but the old battery is going strong in one of my classics.
Should have been £65 but with ebay discounts it went down to £52.
Its an exide battery the same as the mopar ones and the capacity matched.
Works great
 
It’s EFB battery - says so under the strap
It reads “Attention: Enhanced Flooded Stop/Start battery”
New one has higher cold cranking rating too:

And yet '77% health' wouldn't be a trigger to replace on most cars, I guess? (I just replaced my 12V in the i3 at 47% health because 50% is usually held to be the tipping point on i3s)
I would tend to agree but these Pandas do seem super sensitive. What we see above is a snap shot possibly after the car is started and or running (presumably as it checks the "charging") whereas warning lights are triggered by the self check at start up after cranking so pretty much worse case?

Plus I think OP said mainly short runs to the stable so it there's probably a cumulative volts deficit?

Of course battery may just want out because of the disco lights?

Oh I wasn't suggesting non-replacement, I was saying what you've just said in a more oblique way, as is my custom :giggle:

It's a disco inferno, for sure.
 
actually, most newer cars have this super-sensitivity. Trouble is they tend to be trying to run the self-checks at the same time you’re operating the starter, so the voltage at the sensors has been pulled down at ‘just the wrong moment’.

A bit of light reading on what happens to the battery voltage and effects on other systems during cold cranking - Linky
 
77% is likely to run the car but systems begin to get grumpy.
50% is likely to be when the car just wont go.

So i guess its your choice over what level of service you want from your car. Now because it is under warranty with your supplying garage i would take it back to them and tell them of the issues you have had. I would advise them at this stage of your discussions here. They can then choose to investigate and deal with the issues and may come to the conclusion it needs a battery. You can wait for thier response with the knowledge and experience from here. If they change the battery then you get a new battery fitted and this should last 5 years.
If they charge the existing battery and give you the car back and further down the line the issue reoccurs then its a continuing problem. Straight back to them.
 
Come back to the start…
Four lights.
One is a tyre pressure error. It doesn’t know what the tyre pressures are — it uses the ABS sensors to see if one wheel is going a bit slower (which it would with a soft tyre). The ABS sensors are also used by the ESC system. I think there’s been a previous thread with similar warnings?

The yellow triangle normally has an accompanying message on the dash, such as ‘check number plate lights’. But there is one situation where no message shows, and that’s when the Earth connector to the oil pressure switch fails (but usually only with the TwinAir engine)

The general engine fault light can caused by all sorts of things and to be honest, only a code reader can tell you which one.

So, while we’ve all said ‘battery’ I’m less sure it is. The normal series of warnings with a low battery appear as written messages, and tend to be ‘ESC unavailable’, ‘Hill holder unavailable’ and ‘4x4 unavailable’. And you’ve not seen those? And not normally the ‘check engine’ light.

If it’s a twin air, see this thread:

A plug in OBD ‘thing’ is cheaper than a battery, and for many things the free CarScanner app is pretty good. The Fiat-specific MultiECUScan software is better but £50 licence.
