CX-5 Battery Replacement recommendation?

[MEB]

I need a new battery for my 2016.5 GT AWD CX5. I am replacing the original battery, so this is my first new battery experience. Should I go with the "Mazda" battery @ my dealer 2yr replacement warranty / 84MO (prorated) warranty $250, includes labor.

If I buy on my own, what brands & specs. should I consider beyond the right type / size for my CX5? Will I need to "re-set" or lose any existing saved functions with a new install?

I need to replace within the next 5 business days. I'm the orig. owner of the car. It has 48K miles & I've not had any issues with the original battery. I live in the Seattle WA area and my car is not garaged. I plan to keep this car for 2 yrs.

Thanks for your recs!

These "discount auto parts" stores are all a sham with their overinflated pricing. NOTHING discounted at all and most items can be found on rockauto for much much lower or amazon if in a pinch. I LMAO at their prices, coupons or not, they're way above reality IN FANTASY LAND. For example, I needed to purchase a simple coolant temp sensor for a 2006 honda civic. Local autozone, advance or O'Reilly's wanted $55 to $60 for that. Rockauto they're $15 to $20 for a good brand. Same brand on amazon, $25. In no way does it justify a store to charge nearly triple for something. If Costco can sell this battery for $125, then you know how much markup there is at these "discount stores and how much money is burned if a person doesn't know any better.

These things are easy to install folks. Learn it once, get the knowledge and satisfaction and be smarter for life.

Yes, I buy from at parts stores only when I'm in a pinch. Like oil, ATF or coolant.

As a rule, I don't buy any sensors from Rock or parts stores. I tested several in the past and they have different resistance and magnetic strength than oem. Other sensors were longer and hit the reluctor wheel, killing them.

I have a closet full of bloody t shirts from cheap, parts stores sensors.

Just because they don't throw a code doesn't mean they are in calibration. Been there too...

A closet full of bloody shirts, eh?

Perhaps your installation methods need a bit of adjustment?

I would suggest wearing red shirts whenever you work on your cars.

Does a 2022 CX-5 without iStop require the Battery Management System to be reset with a scan tool!?

No

I bought a battery from costco and replaced it myself using a 10mm wrench in less than 20 min. It was the first time I changed a battery.

So long as your battery does not corrode badly at the terminals, if you want your battery to last, hook it up to a tender when the car sits for long periods, esp. in cold weather, after short distance drives, that should help the battery last longer than what battery you buy,

Huh went down a buck. Pretty sure I paid $125 even plus tax in 2023 when I replaced a Costo Interstate I had bought for $75 in 2018 which replaced the original battery.

I'm on my 3rd battery. So far so good on this one.

+1 for its easy to replace yourself. Remember you'll need a 10mm deep socket for the bar that goes accross the battery to hold it in place. The nut sits fairly far down on the threads so a regular socket can't reach.

On my previous car, a Mazda CX-5 GT AWD Premium Plus, the last battery I've installed was an AGM battery 665 CCA or something around that number. I can't remember exactly. But it was AGM, group 35 over 650 CCA. It worked flawlessly.

I had to replace mine in 2023. Got it from Walmart for $139.94 before tax. The original battery lasted 5 years.

Yep! I bought the car in 2013. Replaced the factory battery in 2018, and replaced that one in 2023.

My current one purchased in ‘22 from Costco was $99

I have a couple old batteries that that allows me to wheel in a core at purchase time.

It is still showing around 95% health using my tester. I usually replace them when health has dropped to 75-80%
