Keep the unit dry when not using it.,

I had to buy a replacement transmitter for my Polar heart rate monitor because I must've not read the fine print that said dry off the transmitter when not using. Sweat moisture activates the transmitter that drains down the non-replaceable battery. I failed to dry the unit when I quit exercising, so the battery ran down quickly -- about 10x quicker than expected. Not too bright of me considering I have an advanced degree in engineering. So I'm telling you all now.
BTW, the new one works fine. No problem.

Works well, but battery doesn't last too long,

This review is from: Polar T31 Non-Coded Transmitter and Belt Set (Sports)
I am on my second transmitter-chest strap in three seasons. The first one lasted approximately 100 hours of wearing the belt and getting a heart rate, not sure if that is good or bad. I read somewhere to wipe down the transmitter after each use and store in a dry place, or the transmitter continues to try and produce a signal thereby using more battery. So, now after each use I wipe down the transmitter and make sure the strap, while still wet doesn't touch the back side. The strap has some antibacterial as there is no odor after repeated uses without washing (I tend to wash the strap after 2-3 uses). The strap synchs nicely with the crdio equipment (Precor) at my gym. I hope by following these tips I get more hours out of this transmitter than the first one.

Exactly like my old transmitter and belt.,

Ordered Polar T31 to replace a lost or stolen transmitter. It came in perfect condition in original packaging. Worked perfectly with my old wrist watch from the previous belt.
