Can a Polar S610 chest strap with a dead battery be revived?
The battery in my Polar S610 chest strap has reached empty after 4 years of intermittent use. The dying battery manifests this symptom - every time when the watch was moved more than 2cm away from the chest unit, the heart rate display would disappear.

The cover to the transmitter is tightly sealed enough to resist the most dexterous prying with a screwdriver. Obviously, Polar did not intend for the user to replace to the battery. ;-) Aha, a chest strap that is meant to be disposed after the battery is flat - how eco-friendly!
A paragraph from the S610 product manual where good corporate citizen Polar promised to recycle the transmitter!
Not to be deterred by a sealed cover, I used a sharp knife (box-cutter) to cut along the cover edges. Opening the rear cover reveals the transmitter Printed Circuit Board (PCB).
The label proudly says, “Made in
The transmitter’s PCB from behind the chest strap.
After lifting up one side of the PCB, the battery compartment can be seen. It contained a depleted 3V coin battery - Panasonic CR2354.
I can’t find a replacement for the battery despite making many visits to watch shops and electronic components suppliers. It appeared in the 2009 RS (a mail-order component vendor) catalogue. But inquiring with RS, I was told that it has been obsolete. What can I do with a dead chest strap?

Try asking at Athlete's Circle Malaysia .in Jaya 1, Petaling Jaya Tel: +603-7960 2313 ( the officecomplex opposite Swct 17 PKNS flats). I hear they service Polar's
Chin Leong, You can coming to my place I have two new batteries you can have it Panasonic CR2032 3V. Same size. worth trying
YB, Thanks for the offer. Although having the same diameter, the CR2032 is so much thinner than the original battery that the terminals cannot make good electrical contact. However, in the event I cannot find the exact replacement, I might consider modifying the terminals to suit the CR2032 - this will be the last resort..
Lee, Thanks, I will email AC as u suggest. but I doubt if they will keep spare of something that is not intended to be replaced. their principal had intended for the S610 chest strap to be replaced with a new one when the battery is depleted - so user replacing the dead battery will affect their business like refilling printer ink cartridges.
Have u registered for this coming night run at Putrajaya, this Sat. I heard many are going for this night run including me.
