I have a 2002 S-80, 2.9.Because the "low battery voltage" light came on, we had the batterytested and it was low. We installed a new battery just yesterday and I again am getting this same warning. What could be draining the battery?

 

I can only assume one one of the following:

- The warning must be reset at the dealer.
- There is a parasitic drain somewhere (glove box lamp, dorm lamp, etc...).
- The new battery was already low on charge/electrolyte (unless it was Volvo Battery or the Interstate Battery).

Wait for others opinions as well.

Most likely the alternator is bad.
