Battery Bosch or OEM Subaru
Still on vanilla battery. As part of my wife's start process is start car, press button to turn off auto off. Seems to be working.
Our car straight up died on the road twice, to the point it couldn't be jumped, with my kids in the back seat. Subaru eventually gave us an upgraded battery.
if you have a costco membership they sell the bosch batteries for a bit more but theyre amazing. 4 year warranty too
I noticed that between 4ah and 5ah battery is little difference, but not much, 15% i would say. BUT 5.5 procore seems like 50% better than 4AH bosch battery and at least 15-20% stronger than bosch 5AH battery. When i say stronger, it is noticable in speed,strenght when i cut pellets, or drill concrete, or doing some 100mm or larger screws.
OEM Subaru batteries and not the best. When it's time for replacement go with a 3rd party battery.
My car does not start well. I had replaced the battery myself, which helped it not be so bad.
Replacing my battery recently
A new battery at 10k miles.
Battery died around 50k miles.
I bought a brand new Bosch battery last year ( not Halfords)and when I checked the voltage it was less than 10 volts so there are dud batteries out there.
