Battery charge

[Johnmed]

Hi all.

I fitted a new battery, Bosch S5 before Christmas. Brother in law suggested it wasn't good as it was 12.7 volts. I said it was equivalent to 100% SoC, having googled it. I then had a low battery warning, he tested it and it was 12.2. So I exchanged the battery at Eurocarparts on Monday. Today, having driven 70+ miles I had VCDS on it to add the Webasto menu to MMI. So I had a look at the battery regulation module. See pic. Is 12.4 low? On the battery there is a Bosch sticker that says 12.4. Should it be higher (12.7-13.2v) or am I missing something?

All the best.

John.
