Wrong battery put in crosstreck

[Ren_chapman]

Hi!
Question: Could the starter have been damaged by the incorrect battery being put in?

Context:
I have a 2019 Subaru crosstreck and I had the battery replaced in January at jiffy lube store 1 and began having starter issues shortly there after. Went back to Juffy lube store 2 in March and they told me the wrong battery was put in my car. Store 1 had put a start stop battery in rather than a regular battery. Had to go back to store 1 to have them fix the issue per policy. They replaced the battery very begrudgingly. I got the car assessed by a Subaru dealership and dealership said it was fine, this can be hard to tell tho from what I understand.
Few weeks later my starter went out and I had to have it replaced at the dealership.

Could the starter have been damaged by the incorrect battery being put in?

Thank you in advance

Amps are pulled, not pushed. You could damage a battery that was too small, but unlikely the starter.

NOT LIKELY !
The More Battery Capacity , the More Amps , the FASTER the Start is completed , the LESS HEAT in the Windings: Starters are damaged by Low-Amps causing Protracted Starter Operation , not the reverse process . BTW , a Fast Spinning Starter actually runs COOLER than a Slow Starter ... again less long term Damage , wear-n-tear(s) !
Most likely the Starter was damaged by the first Low-Amp Battery, then finally gave out but only after you had a Better Battery installed ...

Not at all likely unless they somehow managed to find a higher voltage battery which is extremely unlikely and would have cost much much more than a standard 12V automotive battery.

For Reference , check out additional Info @ :
https://poweringautos.com/how-low-should-battery-voltage-drop-when-starting/

Again , when Voltage is Low (weak-battery) , the Starter will draw a LOT MORE CURRENT, and this causes excessive Heat (I-SQUARED-R) in the Starter Windings, etc. Said HEAT can and will damage a Starter, especially if the Operator repeatedly uses a Weak battery , until it no longer will Start a Vehicle ! The Extreme situation is what is called LOCKED-ROTOR Operation, and with a Locked-Rotor , a Strarter can draw 800-900-and -up-to-1000-AMPS ! That will fry most automotive Starters !

A FAST spinning Starter Rotor produces a significant BACK-EMF through the Magnetic Effects of Current Flow , and keeps the Starter current at relatively Low-Safe-Levels !

The battery chemistry is essentially the same for all automotive batteries. The differences are in construction. There is the type we are all used to. There is a gel type which are not used in vehicles because they are deep cycle design for use inside buildings for things like a UPS. The AGM use a mat between the plates that the electrolyte soaks into and they are generally more rugged than the conventional battery.

The type of battery that was initially installed by jiffy lube is just like the conventional battery, same plates and electrolyte, but it has a lot more, but thinner plates that are spaced closer together. This reduces the internal impedance of the battery. To understand the importance of this, you would need to take a college course in the electrical engineering department on the Kerchoff Loop Law. Not enough room here to cover that topic, but the short answer is you can use a start stop battery with a normal starter, it wont hurt it. But it doesn't help either and the battery costs quite a bit more.

If you use a conventional battery with a start/stop starter, you risk damaging the starter motor if the vehicle is in start/stop mode. If start/stop mode is turned off, then the starter will be OK with a conventional battery.

Your Understanding is ... EXCEPTIONAL !

I have Electrical Engineering Degree from 1960's University Of Illinois , and I fully agree ; but I needed "modern" Fetching-Up, so I recently started Reviewing Industrial-Practices on a Web-Site called "The Battery University" { www.batteryuniversity.com } , and also obtained a Copy of Buchmann's Book "Batteries in a Portable World" ( most folks do not know the Difference between Stationary-Batteries (Pure-Lead) and Automotive-Batteries ( Lead + Cadmium + Antimony, for Shock & Durability ) , nor between Portable-Batteries and those other two.

These TWO references prove everything that you say is true , Plus a LOT MORE ... !
Thank-You for vindicating much of what I have been Proposing about Batteries around the Internet for a Decade ... !!!

Went Searching : DC Motor Power vs. Current Draw :

voltage, current, torque and speed in DC motors

First off, please don't accuse me of not doing proper research before asking--I have done much research, but I could not find any answers that made sense to me. I have been playing with some DC mot...

electronics.stackexchange.com

Essentially , this author says that any DC Motor is Current-Limiting by the Back-EMF, and as such, it is not likely that any Capable Battery ( can supply the needed AMPs ) will be Damaged by A.S.S. (Auto-Stop-Start ... !!!) in any vehicle ; so the Back EMF "should" ensure the Safe operation of any type, style, chemistry, Design .... as long as it can provide the minimum instantaneous Current the Motor needs .... which is highest (opposite to a Capacitor ..!) after the Motor starts drawing Power near its Required Torque Value , see their graphs down into the Article ( Lagging-Power-Factor ).
