Salt Cell Replacement Question

I am in Middle TN and just bought a house with a fairly large pool - Guessing \~40k gallons. It has an AutoPilot Digital system and AutoPilot Salt Cell.

I am having the pool company down the road that maintained it previously do the maintenance for the month of September while we are getting settled in and I have more time to learn the ins and outs. I plan on maintaining it myself moving forward. They are telling me the salt cell needs replacing and want $1500 to replace. I did confirm after cleaning it myself that it will need replacing, and it is not too hard of a job so I will just do it myself for much less money.

My question is since we only have a week or two left of swimming weather, is there any point in replacing at this point in the year versus just waiting until warmer spring weather? I plan on keeping it open all winter at least for this year, and my understanding is after the temp drops below around 60F that it wont generate chlorine anyways - and we are not too far off from reaching those temps consistently...maybe another month or so. Am I just as well off to leave the old one in for now, maintain the pH while temps stay warm and throughout the winter, and replace later in the spring once the weather warms again?

I'm obviously a newbie so any insight is appreciated. Thanks
