hi i just got a treo 750 from a old time friend.. but he lost the battery.. and i looked everrywheeerre for a 680/750 battery.. but couldnt find one.. so i ordered one from here .. gets here on thursday.. but anyway.... i put my 700wx battery in.. the 750 turned on.. but the charger wouldnt charger the battery.. well my main question is.. is it normal? is it normal that the charger wouldnt work cause a 700 battery is in it.. or would i have to have a 680/750 battery for the charger to work... sorry i think this is the best way i can explain it.. ask any questions if your confused...
