does anyone know if a (napa) battery #7535 could or should work in my 2013 Mazda3 (skyactive) 2.0L hatchback? i've always had the (napa) #8435 but would like to swap it out for a day if possible and if it wont mess with the electrical system so i can take the #8435 in to get super charged as its currently dead from sitting while out of town too long.

It's not exactly ideal, but if the CCA rating is similar then you'll be alright.

There are a few things to consider when getting a different battery than the one specified:

1. Dimensions. If you look at your current battery, it is housed in a battery box. You need to make sure that it will fit in that box, and shouldn't be more than 1/2" taller than your current battery.
2. CCA rating. More is better, but you can probably start that car just fine with anything over 350 CCA. But I like 500 or more for long-term health.
3. Battery post positions. You need to make sure the positive post is on the correct side of the battery. Never cross your battery cables or yank on them to "make them reach".

Listen to @RocketmanKarl about the post location matching up ... for CCA go for the max for same size battery that fits exactly which would equate to
having more battery charge capacity - especially needed in those new smart crazy gadgets 3's.

If you want a battery with extra capacity then you will have to go with a lithium car battery

While I like the capacity of lithium batteries, I'm not a fan of them as a car battery. Lithium batteries don't do well in high heat or high vibration environments. Seen all those videos of people's phones and laptops bursting into flame? The last thing I want to see is my car burnt to the ground because I hit one too many pothole... The plain old lead-acid battery works just fine unless you have unusual needs, like a massive car stereo or you plan on camping in the car.

I hear ya.
But the only times i have seen an issue with lithium in cars if when using motorcycle batteries or batteries that have no low voltage cutoff or overcharge shot off.
Bikes shake alot. Once the voltage drops below 10volts charge you need to plug and recondition it back. It only becomes an issue in high amp charging when at 10v volts or below.
The cells cant take the amperage and battery starts melting. The lithium battery in phone and laptops is not same as LiPo in car/bike starter batteries.

Take it from experience. I had a shorai battery (4lbs /380CCA) that i let get too low a voltage and when she would not start i boosted with a portable lithium car starter
and melted into a jello ooze.
The anti gravity battery LiPo have a low voltage cutoff and overcharge shutoff. I replaced the shorai with an anti gravity 3lbs / 420 CCA
Shes a small and very light battery only worry is capacity. cant leave her parked for several weeks / month. Got to drive her once a week.

Hey Karl you know all those catch on fire Li batteries can be found in all new EV's ... they dont really talk about much about that.
We'll probably get used to it like we have with our gas cars and the explosive liquids we carry to run them.
At least gas dont explode when going over a pot hole .. )

Wooooo! This got a bit deep 😆 The OP only wants to swap it out a day 🙊

Do a little search on YT for "tesla fire". They do catch fire at a rate far higher than lead acid batteries. Pack more electrical punch into a smaller package, and the chance those packages short out and "let the smoke out" goes up. Sure the old lead acid batteries are heavy, don't last more than 5-6 years, and have limited storage, but they get the job done without bursting into flame (well, they do explode, but very rarely).

As Pez said, we're way off topic here. I'll kick the soap box back in the corner...
