Battery Deka or OEM Volvo

I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.

Deka batteries. I’ve turned wrenches for twenty years and they’re the only ones that still consistently test far above their rated capacity when new. I have one that’s 7 years old and just installed one in my other rig last year.

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.

I\u2019ve owned an S60 T8 for 2 and a half years now. Like others have said Volvo PHEVs deplete the battery first by default before touching the gas engine.

I have been driving a 2023 S60 Recharge for 2 years now. If someone told you it's bad to drive them with the battery depleted, they lied to you.

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.

Deka. Solid battery.

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.

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).
