Help What to do first....drain or charge battery?

First charge: When you first unbox your tablet, you should approach the first charge differently, depending upon the type of battery the tablet has:

Lead acid: The battery should be fully charge. Apply a top-off charge before using.
Nickel-based: Charge the battery 14-16 hours before the first use.
Lithium Ion: Apply a top-off charge before the first use.
