[Q] Properly Charge Out Of Box?

[lardo5150]

I thought there was a thread or post that stated how to charge this thing out of the box.
I can't find it by searching now.

Out of the box, what should we be doing?

Full charge, halfway then let drain, etc..

Let it drain (within 2%). Charge fully. Drain again. Charge. Use as usual.

This isnt necessarily transformer-specific but applies to Li-ion batteries in general. Fully charge (the instruction manual that comes with the tablet specifically says 8 hours), fully drain, fully charge. After the second charge, use it as you want.

I keep reading a variety of ways people approach battery issues and I meant to post this in its own thread. I'll try and do it today.

I believe I am summing it up correctly by saying... Most manufacturers ship products with the battery approximately 40% on purpose. You should charge your device to 100% when you get it. After that, you can essentially use it normally but they recommend you never let the battery drain down very low - that is not good for a Lith Ion battery. I take that to mean not letting it get below around 10%. So, the first post is essentially correct except that you shouldn't let it go to 2%.

For ongoing use, the site recommends charging when the device is off (I know we can't always do this) and never letting it drain down very low. "Top off charges" are fine.

Here is where their summary table is:

But.... poke around the different topics if you are really interested.

I did wonder about "battery calibration" too but I *think* that is only necessary for devices you never let run very low. For example, a laptop you leave plugged in most of the time. You can find their discussion at the link near the bottom of the left column.
