Battery OPTIMA or OEM Volvo

IMO, the Optima Yellow top is your only option. It will last 5-10 Years.

Absolutely not true. I use an Optima battery, works great. Have for a few years now since my 2nd garbage oem battery went out. Or was it the 3rd?

I installed an Optima yellow top in my 2023 OBW. Works fine!

Currently running a yellow Optima, 3 years and going strong. I don't recall what the OE battery was but it crapped out after 2 years in mild California weather.

I had an older optima yellow top last about 10 years. I miss when that quality was available

My wrx would be parked for long periods and I had optima yellow tops. I liked how hard it cranked, good for e85 cold starts. But wow, after the second one went flat I stop getting them. Bought some random battery and it\u2019s been holding charge no problem.

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.

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).

Optima batteries are absolute trash for deep discharge use. Their quality is also not what it used to be. Anytime I see them in marine use, I swap them out for a proper AGM. Only thing they are decent at is starting applications in cars.

I bought a red top.. in like 3 weeks it wasn't taking a charge and it got returned. Never again
