The difference between 1440 and 1500 is trivial and probalby has to do more with a change of mfg source than a change in capacity. I couldn't find anything on ebay, but there finally are some cheap battery+charger options available. I might buy a 2 bat+ charger for the Moment. I had a similar setup for my Touch Pro. This way I could carry a charged spare with me and have one in the charger. So far I've had a bit longer life with the Moment and haven't had as many days of coming home with a dead or almost dead battery. I want to get a similar setup for the wifes Pre which has lousy battery life, but she doesn't want to carry a spare battery or remove the cover. Instead, she prefers to complain.
