My own experience with Odyssey PC925 (or it's red top equivalent) on my +8 was appalling I had 3 new batteries in 4 years, including the original that was a battery a year. In the end I relocated the battery to the trads original (and current) position at the back, stuck in a cheapo conventional battery and problem solved. Not a solution available for Aeros I suspect.
Some people on this Forum have reported 7 or 8 year battery life with this thing, but I think that they are the work of the devil.
