hello, I'm considering to buy a newer technology battery for my trusty old powerbook titanium g4/550 mhz. they advertise their battery with 17% more battery capacity than apples original battery. (see http://www.newertech.com/newer_bats.html) does anybody have experiences with this battery? I would like know, if this battery is really better than apples own battery and especially how long it would be in such a good condition (month, years). furthermore I have the problem, that my powerbook doesn't warn me about low battery status (I use the original apple battery, now almost 4 years old). my powerbook simply goes off without a correct shutdown, if the battery is empty. should this problem also be solved with a new battery? thanks for your suggestions in advance! best regards, ferdinand --
