Battery Deka or OEM Volvo
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
Pros: lasted 7 years
Vehicle:
BMW
Part number: AUX18L
I use Deka sealed batteries so less offgassing messing up terminals.
Pros: less offgassing
Cons: messing up terminals
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.
Pros: lasted 22 years, endured Swedish winters
Vehicle:
Volvo 940
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
Pros: stayed alive for 8 years, long lasting
Vehicle:
Volvo S60
Mileage: 238182 km
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
Pros: lasted just under 10 years, remarkable lifespan
Cons: much more expensive
Vehicle:
Volvo
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.
Pros: lasted over 13 years, good in cold weather
Vehicle:
Volvo XC60
Mileage: 249448 km
Didn’t even have to replace the battery in that time (11 years).
Pros: long lasting
Vehicle:
Volvo XC70
my dishwasher has around 200 mile motorway range on a 64kWh net battery, which'll get me from Oxford to Darlington on a single charge, I could get to Newcastle if I camp behind a truck for most of it. My car is also stupidly inefficient for an EV, better EVs like a ID.3 or Megane could go further with smaller batteries.
Pros: 200 mile motorway range
Cons: stupidly inefficient
Vehicle:
Volvo
The battery is almost certainly dead.
Something else wrong with your car likely killed the battery and if that's the case buying a new battery will just result in the same problem pretty soon.
Cons: battery is dead
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
Pros: screaming dead cells
Cons: battery is cooked
