My X3i has been acting weird for a longggggggg time now. Ive posted for nearly 10 months now with the same issue with no resolution.
The unit continually says the "backup" battery is dangerously low, yada yada. From what Ive seen, there is no physicall backup battery to replace. I purchased a new main battery the other day hoping for the best, with no luck. Same issue. The X3i runs like a slug too. Its no better then a paperweight!
