I got off the phone this afternoon with anti gravity... Sent them my dead 12 cell two weeks ago and had to call them to find out about it.
They said because I ride "freestyle", the battery can't handle the starts and stops and they're going to revise they're warranty policy to reflect that.
They won't replace my battery.
They offered an upgrade by paying the difference and then they'd take 10% off. He didn't even want me to get a 16 cell, wanted bigger.
I talked him into the 16 cell, which was $70, minus $7 plus $12 for shipping. So $75 more I'm getting a 16 cell- with no warranty...
I guess if/when this dies, I'll take my chances again with them, but they're not getting anymore money from me.
