    The OEM Varta battery in my Daihatsu lasted 10 years. Less than 5 years would be very disappointing. But the start-stop system may have an influence, too.

    Can you post the exact Optima yellow top model number that you got for your Mirage? Did it fit right in the plastic battery cover?

    It looks like I will be replacing my battery in the next few days. The temps here in Texas dropped about 35+ degrees F today and i think that might have pushed it over the edge.
    I have kind of been "milking it" with my battery, knowing that it has been getting weaker and weaker over the past few months. I have drained the battery a few times by accidentally leaving the cabin light on in very little time. Also, a few times after not driving the care for a few days, it will struggle to start. This temperature drop, plus the weak battery, I think it's on it's last leg after I get it charged up right now.

    Any suggestions as for different/stronger batteries other that the yellow top mentioned above?

    I just had mine tested by the Mitsubishi dealer. It tested a 297 out of 360. This is on a 2014 Mirage with 23000 miles on it.

    I guess it would have been of additional benefit that I would have added that I crossed the 100k mark a couple weeks ago. Mine being a 2015. I've had the little gem since Nov. 1 2014. So, I guess only now having to change the battery might not be all that bad.

    Miles on the vehicle are not what wears a battery. Frequent usage (as in discharge/charge cycles,) depleting it's electrical charge and/or electrolyte, and extreme temperatures will. To run the car for extended periods will prolong the battery life with consistent charging. 100,000 miles sounds like a lot of extended highway driving.

    Here's some further info.

    My battery finally failed this morning....at 111k miles. The car was built Sept. 2014 (a 2015), so not too bad. Started cranking a bit slow this week, with temperatures in the 90's.
    I'm used to getting closer to ten years from a car battery, but this one is probably typical of most

    Almost 7 years from a factory battery 55D23L (356CCA/99RC) that's only 356CCA to begin with isn't that bad in my opinion. I've never known a factory battery to be all that great in any brand of car over the years.

    Curious what you will replace the factory battery with?

    My favorite.....Walmart Value Everstart...54.00. Group 35.
    500cca
    I've bought two of them for other cars, one is in an old bucket truck and sits a lot. Installed in March 2017, still works great.

    I sort of checked battery prices after I asked the question, & I would have done exactly the same.

    I've used Auto Zone @ times in the past, but their prices are quite high now.
    Their basic Duralast battery (group size 35) is $150.
    Their Gold Duralast is $170, & the Platinum is $200.

    Those prices make the Walmart Everstart Value (approximately $55) & Everstart Plus (approximately $70) seem like a good value. Many of these batteries are made at the same factories with different stickers slapped on them.

    Did the top clamp/J-hook bolts fit your new Everstart Group Size 35 battery?

    Seems to be some where having issues with that, but you can buy longer J-hook bolts for a few bucks.
