DIY: Battery replacement (with slightly higher capacity)

[alex16]

This might end up being a basic diy but still hopefully helpful to y'all in the future!

Long story:

I drive my mirage commercially and put about 10-14 hours inside it every day, I try not to idle those 10-14 hours as much as possible but I still need my cell phones charged. The factory battery has become very weak over time, 330cca when new is more like 150-180cca now. It has plenty of power to start the car and run the radio for 30 minutes, anything over 2 hours and I'm unable to start my engine. It's gotten worse over the past 6 months and decided it's time.

Short story:

Finding a replacement with the most cranking amps to fit in stock location. No parts stores are currently showing a correct size. I measured and compared all the batteries they had on hand at Walmart (my favorite place for car batteries) and found a 24F maxx ever start is just slightly longer but similar width and height.

Will be installing in about a hour. Having lunch and going to auto parts to get a 10mm
