Battery Deka 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.

UPdate - new battery and bluetooth 12v monitor installed last Monday night, all good since then including one day with 40 miles of driving and recharging in weather well below freezing (16 to 28 F), but I happen to be mostly driving other cars the rest of the time since.

FYI, altho I ordered from Remy, the sticker on the battery I received says [Deka Intimidator EHP](https://remybattery.com/batteries/brand/deka-intimidator-batteries.html?srsltid=AfmBOorxsFi7eoMbizQPDMsF1q-32WuvMxLPyiLSgftX8ExWmqHWSfq4). IDK if there's any functional difference - it seems to have the exact same terminal connections as the OEM BMW battery it replaced.

Also FWIW, despite no indicator on the shipping box for 'this side up' and it clearly getting Ace-Ventura'd around by FedEx, it did not leak or show any signs of damage inside the shipping box. It was well padded with foam made to fit the battery and fill the entire shipping box. So far I'm happy and the car seems to be too.

OEM for Harley. I've replaced several with an average lifespan of 5 yrs at 20%+ cheaper than Harley branded

As a harley tech I see more aftermarket batteries fail then I see oem ones fail. There are a few good aftermarkets like DEKA but for the most part aftermarket batteries seem to fail quicker then oem.

OEM Subaru batteries and not the best. When it's time for replacement go with a 3rd party battery.

My battery died on my ‘15 Outback within a year of my buying the car brand new off the lot. I noticed some issues with the lift gate and the car was having problems starting at times. It was a bad cell in the battery so it needed to be replaced.

I had this issue as well, one day the car wouldn’t turn over. Then it would. Then there was no power. Then it would start. Over several days and weeks this would happen. It was explained to me that the Subaru batteries that come from the factory are made to hold just barely enough power to start the car. If that power is diminished in even the slightest degree, like with normal usage in the first 50k miles, then the battery does not have enough charge to do its basic task anymore, rendering it useless. As I understood it, the batteries in the new cars are not up to snuff.

Replacing my battery recently

A new battery at 10k miles.
