Hi, does it work with polar A300 and are batteries included? Thanks in advance, V

Yes it works, it is only a chest strap, no batteries, the batteries are in the H7 /H6 / H1 or H2 transmitter which you will be using which attaches to the strap

Does this chest strap have a warranty or guarantee?

I don't know, but mine has lasted for ages and ages. However don't dry them in the washer dryer!

Hi. will this work with my polar rc3 gps? my watch keeps stating i need to check heart rate monitor & battery low even though it’s a new battery

I cannot answer that question ,I bought it to use with my garmin edge cycle unit and it worked just fine. I bought the polar strap because my garmin strap kept breaking. I have had the polar strap about 3 years with no problems and it fit perfect with my heart pluse sender unit. Cheers
