different charging with motorola vs cheap axe cable?

[OBLAMA2009]

so ive noticed that when i charge my phone with my motorola cable it says "fully charged" when charged and when i use a cheap axe duracell charge it says "charged" when presumably fully charged. does it matter? is the cheap axe charger fully charging the battaree and if not, might i have to "recondition" my battaree to get a fully charge from my motorola charger after ive used the cheap axe one?
