I am not for sure if Home Depot takes in " old Sump Pump Batteries. It probably would be good just to call up to the Home Depot nearest to you or where you go to. I can look into it. And find out if they do or not Soap Soap. And get back with you.
I’m not 100% positive but I knew they were taking all batteries.
Try interstate battery just around corner.
They used to take all batteries, with covid, I'm not sure, but call your local store and the rental department can assist you with any questions
