Thanks for the comments. I guess there is just something weird about my computer.
In the end I went to both Interstate and Battery Direct. For a basic little battery, $48 at interstate and $32 at Battery Direct for the same battery. I asked at both places for the small jell celled. Interstate had nothing small (but did try to sell be one of those emergency light back up batteries which I have tried and had catastrophic failure with ... on a hardtail), but Battery Direct had a small one for $44. The problem with small motorcycle batteries is that they are best charged with low amps. In the end I was persuaded to also buy a new trickle charger which will charge at 0.75 amps with an automatic over charge shut down feature.
The Antigravity batteries do require their own charger which is another bummer. The salesman I spoke with said they hardly ever use them. He said they have one which has been on the shelf for three years and has only dropped 0.3 volts. They sure look good though. Low Brow Customs makes a mounting kit in machined aluminum which is really slick ($70), but for now the flat tracker will remain low buck, so I will fabricate my own bracket to hold my new jell cell.


Peace, Grease, Amps & Ohms, Dennis
