Nearly 7 years now, still on the OEM battery.

That's really good for an OEM battery 55D23L (356CCA/99RC) that's only 356CCA to begin with. If you go by manufactured dated, my Mirage battery is 4+ years old. We had -4F when I started my Mirage this morning. It still started up perfectly fine. I did, however, use the engine block heater for about 1.5 hours today. Temperatures in Wisconsin have dropped recently!

I still have the stick battery in my white 2014. Most of the work cars have factory batteries too.

I’ll trade you weather. This is in Fahrenheit Attachment 20553

Yeah, I don't think -4F is all that horrible. We get those -20F or below at times, but not as often as your area.

Overall, the factory battery don't seem that bad (considering the low CCA rating). A small 3-cylinder engine with 0W-20 engine oil isn't the hardest engine to turn over, & I am sure that helps, too!

Well, the white car didn't start today.....battery didn't have enough juice to turn it over. Time to sell it and buy beer.

Shouldn't have said anything yesterday. 7 years is still pretty good for a factory battery.

I think we got your weather today. -25F this morning.

So just about 4 years and when I asked them to test battery at AutoZone they said it needs replacing and something about 78%

So I assume they are telling me that the battery has 22% degraded in its ablility to hold the charge? I was a bit skeptical since the car shows no symptoms of a battery on its dying legs.

I have a small amp that is 100 RMS as part of my upgraded sound system and dont know how much of a strain the aftermarket touch screen stereo and amp put on the battery.

When I put a multimeter on the battery (myself at home) it registered 12.5 and when I put it under load it goes as low as 9.8 (as the car cranks up)

I have never put water in the battery so Im going to do that tomorrow

Batteries are complete luck of the drawl my friend. I've got a optima battery from 2013 that was a 700cca and now it only charges up to 500 but thats more than enough for most cars. So i've still be using it so we're on 8 years and going.

Keep in mind, a new Mirage factory batteries only starts out with 356 CCA. I had an Interstate battery going on 10+ years when I sold my Festiva years ago. Some do last longer than others! 7+ years for factory battery in a cold Canadian climate is pretty good in my mind (referring to Fummins' Mirage)
