Battery AC DELCO or Deka

I use Deka sealed batteries so less offgassing messing up terminals.

Longest battery I had was from AC delco, lasted 10y! But apparently they are different now.

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.

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.

I'm gonna 2nd the AC Delco recommendation. I have had nothing but issues with Duracell's leaking. I have never had an issue with AC Delco. Its the only battery I buy. The best.

Man do yourself a favour and get either amaron or solite. Both lasted me almost 3 years. You're lucky that AC delco lasted you almost 2 years, the ones I get barely lasts a year, and that's with warranty replacement .

I’m on my 3rd battery since Nov 2021. Every time it has lasted me 1 year and 3-4 months. Not even 2 years.

I don’t have a parasitic drain. I don’t use AC a lot. I don’t jumpstart cars with it. There is no excessive load on it. Yet, they all lasted less than 2 years.
