Hi All,

I've had my Polar FT4 for almost two years now, and the battery (or batteries) have never died. During my workout today, my watch kept saying, "Check Heart Transmitter", was making weird beeps, gave me a heart rate of 215 and then 0.....and that was it. I think the batteries are gone! What do I do? I don't know how to replace the batteries for this thing, or if that's what this even is. Any suggestions?

Thanks guys!
:) Lisa

    Definitely the batteries. I have the same exact hrm. I just brought it to walmart to the jewelry section and they changed the batteries for me.

    Do you remember how much it was for the battery change at Walmart? Also, is it the battery in the black snap-on piece that needs replacing or the watch or both? :)

    Thanks!!

    I have a similar Ft Polar and have had it for four years. I have changed the battery once. I took it to Fred Meyer and
    they were able to change it for me. Usually it starts doing strange things when the battery is going. If you send it in
    to the Polar Company they will also check the transmitter for you. I did that with my first one. They offered to fix it
    or sell me a new one. I decided at that time to buy a new one directly from the company.

    The FT4 has an battery that is easily replaceable. On the back of both the watch and transmitter there is a slot in a circular battery cover. You have to turn the battery cover about 5 degrees to open the back. The best thing to use for this procedure is a US nickel. Don't use a screwdriver. The plastic is relatively soft and you'll end up stripping out the slot and then it will be very hard if not impossible to open.

    Don't take it to a jeweler as it would be a waste of money. Polar redesigned their watches to allow user replacement of the batteries. Older models required that you send the unit back to Polar for replacement as it was a tricky procedure that often ended up destroying the watches waterproof seal. This is no longer the case.

    I go back and forth from Jersey to Eastern LI and drop mine off in Lake Success at Polar and pick up few hours later they check out both battries and change as necessary between me and my son we have a few last time it was about $8 each if not sure call them

    Does anyone know what type of battery to buy? I have a 3V from Energizer but it's too big for the watch.

    I figured it out. It's actually written on the back cover of the watch. I took it to Radio Shack and the guy knew from the number on the back of the watch what battery I needed. I changed it right at the store and it worked!
