My TomTom XXL cooks its battery. I suspect it just has overvoltage protection instead of a real smart charge circuit. One time last winter I left it plugged in for a couple of days and now the 3 year old battery is totally useless instead of mostly useless (life had dwindled to about 30 minutes before the last overcharging, now it's less than ten minutes, was 2-3 hours when new). _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
