I bought and installed an Odyssey PC535 battery at the beginning 2014 for my R1200GS Adventure For the past few months I have had the symptom that when first trying to start the bike after a few days there is little to no power, just a pathetic half attempt to turn the motor over. If I then waited for a few minutes and tried again the battery power seemed restored and the engine turned over and kicked into life without issue; and no issue later in the day or next day. This weekend I have gone to do the same after a week of no use and the battery is absolutely just dead flat.. showing 3.8 Volts on the multi-meter. I cannot find any information on batteries dying in this manner. I have no add-ons attached to the power. I had expected another 3-4 years out of this battery from all that I have read. Anyone got any ideas? I am loathe to spend $100+ on a charger if the battery is just f**ked to then have to spend another $210 on a new one that will never need the charger. I use the bike almost weekly and have never had to charge it. Thoughts?
