I bought a new BMW gelcell battery in May of 2011, temperature in KS dropped this last week, so I plugged charger in last night. Last rode on Wednesday, the 3rd, but when I unplugged it this am to go to work, it would not turn over. So I plugged it in and it started, took charger to work and left it plugged in all day, but red and green light stayed on all day. Plugged it in when I got home and both lights are still on, wonder if anyone has had to replace a gellcell this soon? Dealer was closed today, so I will check it in the morning, but plan to keep charger with me till I find something out. Does a gelcell battery take longer to charge than an acid base battery? Thoughts?
