How many years do you use them?

I'd guesstimate 5 or so on average. I have noise-cancelling headphones that are coming up on 13 years soon.

		I finally fixed my PS3 and came to discover that the controller batteries are just fine. Good batteries with proper BMS seem to be fine to live a very long life.
