I have a SeaDoo Explorer and the problem that I am having right now is that I am not sure if I got a bad battery or if I just got a bad unit all together. I keep the battery stored the way that it tells me to (laying flat with connections facing up). They also tell you to make sure that if you are not going to use it for a long time then charge it once every two months. So when I go to use it I charge it the night before and when I get down for the dive I turn it on and it will run for only a few min. Anyone have any insite on this.
