I have a 2016 Volvo XC70. Ever since I got a new battery at the dealer, I consistently get “Low Battery” warnings. I drive the car fairly regularly even driving over 100 miles every 2 weeks. I turn off radio, auto climate, fan, etc. every time I exit the vehicle. Dealer says battery okay and alternator okay. However, the battery that they put in is much smaller than the battery box. Is that right? I would think the right battery for the car would be the same size as the battery box. I never had this problem with the original battery. Any ideas?

 

What is the part number on the "new" battery?

(is it a 30772236?)

 

It’s hard to see the numbers without taking off the cable and you’ve got a gal here who is not good with engines! However it looks like there are two numbers: Top - 600A EV and below that VO22A. The battery takes up about 1/2-2/3 of the battery box.
