In reality, how long does it take on average to charge a playbook from dead? Mines bee charging for 2 hrs and is only at 28%.

Which charging method are you using?
I might suggest discharging and charging it several times. This might stablize the battery as per my previous post.

Based on a battery capacity 5400 maH, using the included charger which is rated at 1800 maH, it should take around 3 hours, depending on how discharged the battery is.

Using the included charger.
I have brought it down to less then 10% several times and have had it plugged in each time over night, but it will never get past 96%.
I don't disagree with your method of conditioning the battery, but brand new out of the box I should see 100%, especially when I spend over $700 on something!
I live and breath Blackberry in general and love the Playbook's functionality, but if there is an issue with this hardware I want RIM to recall it and get me a new one!

Go back a few pages and read my post on how lithium batteries are charged and some of the factors that charging to capacity.
When I was building lithium battery packs for high performance applications, I would often cycle a new battery pack a dozen times to stablilze it. Just because a battery is brand new does not mean it is ready for peak performance. Many laptop manufacturers recommend that you go through several full charge/discharge in order to condition a new battery.
And I am by no means trying to obscure a possible problem with the playbook battery. What I have been saying in my posts is that the battery and charger performance on my unit is aligned with what I know about lithium batteries and charging. There may very well be an issue with your unit's battery or charger. If there is, it is covered by warranty.

I'm in the same boat.
64GB Playbook and tried everything including discharging the battery and recharging it.
I can never get over 96% on my PB.
Is this a hardware issue or just an issue witht he PB's power management?
I want to know if I should return it.

I ran a quick charging test on my Playbook today. This was 5th or 6th time I have charged it. Charging was done with the charger included with the Playbook.
