I have a Icraig wireless touch screen tablet model number cmp773-GD , and it won't turn on or charge. Why?

If u just got it return it. your battery is died need new one.tip to make battery last longer. when u get a new battery by itself or it is part of something like a cell phone. do not charge most have half power right out of the box. use battery until it is 100% died.then charge it until full don't over charge. it is a trick to make your battery last long when it has a full charge. never leave battery charging overnight if done to much it makes the battery weak and wont hold charge for long. never leave charging cord plugged in when its not in use. when it is power from the socket is still flowing in the charger which is slowly frying it. that why most people go though up to 4 chargers for each device. i hope this helps have a sweet one!!
