Can I change the batteries in my Polar HRM strap?

.....or do Polar just throw it away and give you a new one when you send it back?

I think they do! If you Google search you will find various methods involving scalpels, silicon sealant, and so on. I bit the bullet and bought one of their Wearlink straps and transmitter which allows easy replacement of the battery.

For interest, this is what I found when I cut open the dead transmitter unit; the battery seems to be tack welded to the little spring clip and encased in a plastic holder so despite my determination it looks as if I would do better shelling out for a new one. The receiver battery on the other hand is simple.

I just bought a HRM from Sigma where they let you do complicated things like "change the batteries" all by your lonesome through the use of the "innovative" battery cover
