" From: farna@xxxxxxx " " [] " " I was just reading that if the battery isn't charged at least every two " weeks it could seriously degrade battery performance. " [] " Toyota customer service told them they should " have read the owners manual before purchasing. yeah right! how many people read the manual even -after- they buy? " You'd " think that a simple plug in battery maintainer would be available. A 1A " motorcycle maintainer could be connected to the auxilliary battery " terminals easy enough, but would that get through to the main battery? there's a popular charger hack which lets you charge the prius battery directly from house power. needless to say, toyota wants nothing to do with it and emphasizes it voids the warrantee, not to mention they have no liability for owner injuries etc. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
