Anyone who says that these type of batteries should be charged differently doesn't know a thing about li-ion technology and probably skiped to many classes in school.
Well, you're right Tambur, I don't know a thing about lithium ion technology, other than what I've read here. And no, I never skipped any classes at school.
The OP said she didn't get any instructions with her kit so I told her what my instructions said. I followed the instructions that came with my kit, written in very easy to understand English, and followed the recommendations of some other 510 users on this forum, and that was to charge for 8 hours, use for 20 minutes, and charge for another hour.
You may be right or they may be right, and chances are we'll never get everyone to agree one way or the other.
But, in my mind, instructions are written for a reason so unless I have a very good reason to ignore them, I tend to follow them. However, on the other hand, people have every right to ignore them if they like.
