IRulu Tablet won't turn on anymore
Are you certain that you have progress with full charging?: Sounds like battery issues.
Is the tab an older model? Lithium Ion batteries reach the point at which they are totally spent, finished, and worse than worthless. Until then, and continuously, they spew power--no matter what. That's why that chemistry is used for PC and laptop CMOS batteries---that keeps your settings and the clock going when AC or the main battery goes down or merely is turned off/disconnected. Alternately, internally the connection inside your tablet may have jarred loose, instead.
Replacing or fooling with the battery or connectors inside likely is beyond the scope here. (Remember, this kind of battery (similar to those used in smartphones and cell phones) may explode--even catching fire or otherwise--spewing acids may harm unprotected eyes, skin etc. Have yourself and anyone nearby and involved wear eye protection.)
Best bet--leave the tablet as is: If you are under warranty, get an RMA from the vendor (or the warranty company--or the tablet company) and return (obtain a replacement or refund).
Otherwise, purchase a new tablet--if the tablet is older (than Android 4.0 (Icecream)) that's a great idea. (Even Icecream is getting old now, too.) Otherwise, have someone help you to replace the battery. Obtain repair help from a pro at a shop--or, have a willing and knowledgeable kid or tech friend assist. If fortunate, they may be able to remove the battery (if possible). They may then also help search online, and thus help you to obtain and replace it with one with new--OEM (original equipment) or compatible. Alternately, they may repair a faulty connection for you.
