Battery OEM Toyota or OEM Volvo

I had to change the battery on my Volvo 940 7 years ago, it was the original battery from 1996 Wich means that my battery lasted for 22 Swedish winters.

My 2017 original battery stayed alive for 8 years and 148k miles fascinated me how long it lasted and the fact that the auxiliary battery is still fine

The factory battery in my 2007 S60R lasted just under 10 years, and I thought that was remarkable. Much more expensive than an auto store battery though but you get what you pay for I guess

I just replaced my 2012 Volvo XC 60 battery. The car has 155k miles and the battery lasted for over 13 yrs. I drive in cold weather for over 6months/yr.

Didn’t even have to replace the battery in that time (11 years).

I have a ‘24 RAV4 Prime and a ‘13 Prius V. I can say that my battery and fuel efficiency on both vehicles drops between 30 and 40% as soon as the cold weather hits. Range on the RAV4 Prime goes from 80km/charge to about 55-60km in cold weather, plus the gas runs more often so I don’t go as far on a tank (~1300km winter vs our record 2100km spring/summer).

My 3 years old XC60 battery has been diagnosed as bad 55% last 2 weeks ago, I said to them keep it as I feel they are still good and road worthy. Gonna do a snapshot again at another 6 months to evaluate.

Assuming that it's a hybrid and not a PHEV it should run you about $2,500 to have it done professionally, or less than $1000 to do it yourself. At least that was my experience with my Prius.

That battery is absolutely cooked, sounds like the cells have sulfated to hell or there's internal damage from deep cycling

The fact that it's only taking 72-94Wh when it should be 600Wh is screaming dead cells, and that voltage drop from 12.8 to 4v in 2 hours is not normal even with parasitic draw

The battery is trash - if it was at 4v, the cells are either internally buckled/shorted - or the AGM is damaged and thus will not hold any charge (no capacity).
