2013 V70 D4. Low battery warning signal. Is it complicated.

Get yourself some bluetooth adapter ELM OBD2 Icar Vgate for 15-20 EUR (don't go cheaper than that - the one in the picture) and CarScanner App for Android phone (only 2 EUR) (or iphone?) and you will have much easier life with problems like this.

The handbook that came with the car, supplied by Volvo. Actually titled "V70 & XC70 Owners Manual".

Copied from there (fitting a new main battery). There is no mention of resetting anything, so I assumed nothing more is required:

"Lower the battery into the battery box.
2. Move the battery inward and to the side until it reaches the rear edge of the box.
3. Tighten the clamp that holds the battery.
4. Connect the ventilation hose.
> Check that it is correctly connected to both battery and outlet in the body.
5. Connect the red positive cable.
6. Connect the black negative cable.
7. Press in the rear cover. (See Removal.)
8. Fit the rubber moulding. (See Removal.)
9. Align the front cover and secure it with the clips. (See removal.)"

I do have a similar ODB2 reader, which tells me nothing other than charging voltage. I also have a good Multimeter, which I use to measure voltage. More usefully, my colleague has something expensive (don't know the detail, but he can make my wipers & washers operate with it, for example). Again, this lists no faults related to battery or charging.

I've options ranging from ignoring it (car always starts, even in depths of winter), through to paying a main dealer a potential fortune to make the warning go away, replacing whatever they advise.
