Battry must go - (minus) into the movement and +(plus) facing up. As battery replacement must be done with watch upside down, you must see the +(plus) on battery when it is inserted into the movement and the fit the contact over it.
Do not forget to rate, please.

SOURCE: Polar CS 200 chest strap
For two years I had a problem where the monitor was presenting me with ridiculously high values, like 122% max heart rate. This typically happened on downhills or whenever I exceeded 25MPH (OK only downhills). One day when wearing a windproof vest, I noticed that it didn't happen. I then placed SaranWrap over the front of the chest strap to completely block the wind and it also worked. Then I discovered (while reading the Polar manual about HRM maintenance) that the problem might be that I rarely washed the unit. (Don't understand how this manifests itself as it does, but...) After I washed it as directed, the problem went away, so now I wash after most rides. Fast forward 4 months and the problem has returned, but usually only in the first part of the ride and I don't have to be going as fast. I dabbed on some water which didn't help and the next time added a few grains of salt to a few dabs of H2O. Problem still there. Now I'm trying the SaranWrap method to see if this will help, but as of yet, I can say that wrapping up only the central plastic part of the chest strap doesn't help. More experiments on the way.

The Polar S-410 uses the same watch band as all the other S-Series bands so you can replace with any of them. S120, S150, S210, S410, S520, S625, S725. S810 all work fine.
To get the exact replacement you can contact one of the Polar Authorized Service Centers, and they can send one to you, I seem to remember they are under $15-.
You can also change the watch band style entirely and go with a Velcro style sports band, they are readily available at stores like REI and other sports/ mountain type shops. Take your watch with you to match the width of the original band at the head.
