first battery charge for the kindle 3

kerinta · 04-08-2011, 01:57 PM

Hello eneryone! I just got my very own kindle 3!!!!
At last!
Well now i have to charge it for the first time and i was wondering how long?
Do i have to calibrate the battery like you do with the laptop or the mobile phone? Let it charge longer after the battery icon says its ok?

I apologise if its a silly question.

I cant wait to use my reader!

Thank you!

It's a Li-Ion battery, it should be OK to charge it to full level later. I'd say: go ahead and play with your new Gadget :-)

Note that you can not calibrate the battery but just the charging controller (so you get right values for the current capacity). And that's not strictly needed. In fact, by allowing a Li-Ion battery to drain to the lowest level you do worse for its lifetime than recharging often, even when it's just at 70%. Same goes for charging it to 100%: usually that goes along with higher battery temperature, and this will hurt Li-Ion batteries, too.

Another hint: The Kindle charging controller seems to have two modes: connected to a dedicated USB charger that delivers ~1A, my K3 charges very quickly, under an hour. Connected to a PC, it will charge very slowly here, it takes some hours. Sometimes, it even doesn't indicate charging, though the LED toggles from orange to green at some point, so it actually is charging. I've always found that a bit confusing when I was starting to use my Kindle.
