iSport and Battery life -bad after 5 hours
Posted: Sat Jul 03, 2010 5:21 pm
I am a new iSport user, and I have the wireless version. I have calibrated it and did a fitness test as well. I am enjoying riding with it, with the exception of a battery issue I am having.
I rode approximately 5 hours total time and got a bad battery message! This was riding in 80 degree plus weather, so I would have expected much more life out of the battery. The voltage showed well below the threshold and I was getting crazy wattage readings. Well I figured that one of the batteries that shipped with the unit may have been old, so I replaced both batteries. Another 5 hours of riding and another failed battery test. I went on my ride and then got a battery low message. This time the unit seems to work fine, returning wattage figures that seemed correct. I just looked at the battery screen and it shows 252-4 volts, and I installed it a week ago. (I don't know how long this battery sat on the store shelf as it did not have a date stamp). Looking through the forum I saw posts about units that did not shut off, but mine does go into sleep mode when it should.
Is this a problem with the iSport unit I have? Should I have to set up an external battery riding in an East coast Summer with average temps in the 80s?
Any help or suggestions would be appreciated! I am going to try a third set of batteries. Also can someone suggest a good online source for these 2032 batteries?
Thanks
