I bought my car used a year ago and just realized it has the wrong size battery after noticing an unusual amount of battery room. It has a size/group 26 battery with 400cca when it calls for a size/group 35 with 610cca. Since getting the car i've had to replace the driver's window mechanism by the Toyota dealer and had a rough start one time. Should i wait until this one gives-out or get the correct size battery once i can afford, to? I drive a stick-shift. Batteries in the desert climate of Arizona tend to not last. I also plan on upgrading to Android Auto, if i can be done so free or if not nearly free. I currently have the $40 Amazon SD card that lets me get GPS Nav. Computer functions can run slow sometimes. Especially when auto-syncing bluetooth when returning to vehicle.

My local Walmart Supercenter has 3-yr free replacement batteries size 35 with 610cca not in stock but they have a 4-yr free replacement 24F AGM battery in stock. Which should i buy if/when necessary?

Yeah i immediately did so i don't ruin my alternator nor any other electronics because i've already had to replace my driver's window wiring because it had stopped working and i hard starts at one point. I found a great deal at Walmart, too for a 3-yr Free Replacement battery for $98! Was their last one! Had a professional mechanic install it so i could retain my car's memory and NOT reset it's computer. Costco had it for the same price but i don't hace a Costco card. The only thing i don't like about this battery is it's not serviceable, doesn't let you add distilled water to it when needed to prolong it's life. Walmart Supercenter couldn't install it for me because their auto dept. employees called-in sick for Covid.
BatteriesPlus has a 4 and 5 year free replacememt AGM battery but they're more expensive and i'm poor.

I do not believe a smaller battery is bad- it just will run out of CCA quicker than a bigger battery. Buy what you can afford. I currently have the original battery (3&1/2 years) in mine and there is a LOT of corrosion that I have to deal with so I will go AGM if I can afford it or one without removeable caps. (Note- some people have pried out the caps to add water if possible).

Just because there's corrosion doesn't necesasrily mean you need a new battery. Just go to Walmart and for a $1 you can get those terminal cleaners. That'll get that shit off. They also have the cleaner spray and corrosion preventative spray you can buy, too! I bought 'em and they were like $5 each!
