Battery replacement question after 1000 cycles

I recently got a iPhone 15 base model as a Christmas gift for myself , moving away from android it’s definitely a learning curve and a experience since the last time I had a iPhone was when 12 years ago, this may seem like an no brainer but I found the life cycle of the battery is 1000 cycles here in Costa Rica there is no Apple Store rather a distributor by the name icon that’s authorized by apple by the time I need a replacement battery are they usually cheap?? In Costa Rica things tend to be double for taxes
