13 deisel and battery charging..worry?

[triodesteve]

I'm looking remotely at a 2013 X5 diesel. Still under warranty. The carafax shows that 4 times while it has been in for service the battery was charged.
Is that a thing? Does the battery normally need charging in a diesel X5 or is it a sign of a problem?

Thanks,
Steve

This is common as the batteries do drain when the car has not been driven distances. They probably had to charge it to peak voltage/amperage so that during diagnostics, the battery wasn't causing faults.
When my battery had a dead cell, and before I could get it replaced, I would get all sorts of warnings. Some where the AWD system wasn't functioning. The auto up and down feature of the windows wouldn't work.
Hope this helps.
