I get the impression from the Forus that there are a number of issues when it comes to replacing the batteries in the HRM. I have a red - Run HRM; it's being giong strong for just over 12months, but I'm beginning to expect the battery to fail.
I'm wanting to get a couple of batteries, so my questions are; is there a preferred brand, i.e. Duracell, Panasonic?? Can I expect my battery life to be massively diminshed once I replace the batteris, or were these just historical problems on the straps?
Cheers.
