Hey all. Need some input on something. I have a year and a half old Dell Inspiron 8100. I just got a new Battery for it, which is a 4460MaH and better than the original one I had. I want to make this new battery last as long as possible and I wanted some opinions on care ideas I have heard. One is that if I use the battery to say 80% and then get home and charge it back up, that's bad for the battery? I was told to use the battery completely everytime. But that isnt often convientant for me. If I use the battery halfway down, I want to charge it up to full for the next day like when I have school a few times a week. What's the real story on doing this? I'm just looking for a way to make this new battery life last as long as I can... they are very expensive. Also, the reason I bought this new one was obviously because my old one was going out. It can't even hold a half hour charge.... however, last night for fun I had both batteries in the bays and it looks like the system is setup to slowly pull power from BOTH and as a result the old battery is lasting ALOT longer. So it seems that by buying a new battery, it extended the life of my old one. That suits me just fine.
