Forgot to mention, I did load test the old battery, and it seemed OK-ish.
But it wasn't...
The EPS together with everything else running in winter (cold starting, headlights, wipers, heater fan, brake lights etc.) is a big ask even for a battery in good condition. On top of that, it still needs to deliver the correct voltage to the ECU, BCU and other electronics, otherwise wierd errors pop up (like the clock resetting, etc.)
On our own Pandas I have installed CTEK connectors so I can easily just plug them in for a top-up charge a few times over the winter months.
Almost certainly not necessary, but saves me messing about with battery clips, or getting phone calls about "the red light on the dashboard just came on"!
agreed
i have written many time the Panda is odd on batteries. Measuring isn't 100%
had two fail. One that measured faulty. Would cut out on idle. But the power steering fine. 14.1V when running
other measured okay. Power steering would fail first thing in the morning or reversing into a space. Also 14.1V when running.
Having two cars does help as its a quick swap the batteries over.
