Could be variable reasons -> If you're using generic brand chargers or charger adapter (these have various voltage settings on them and numerous tips for insertion into charging location on unit). This is often an issue with regular cell phones as well. If you don't use the same brand charger (or at the least, one of the reputable 3rd party manufacturers, ex: Belkin)...Most importantly, make sure the charger output matches input of the phone. If you're unsure, check you owners manual for specifications. Do the same for your charger specification. If it's quicker to use the internet. Search the net for your phone model. This also includes the info you need for the charger...Depending on the age of the battery and/or the tablet/e-reader. Again, there could be many variables

Batteries are sensitive to extremes of heat or cold. Notice there is conflicting advice as to whether to completely drain a lithium battery or to charge it when down to 20%. I completely power mine down when not using it.
What is the device, and how do you know its fully charged? =========================== Typcially an android device will require you hold the power for upwards of 10-12 seconds fully to force a reboot. If you do that, and its unable to start/respond at all, then I would likely think you have a button issue, or a false positive with the battery/charging on the logic board. Unfortunately, the later means likely, replacing the tablet
If the battery isn't too far gone, here's how to revive it: Plug the device into the Kindle A/C adapter (not your computer) and let it charge for a few hours. Be sure the charging light is lit -- sometimes a drained Kindle will stop charging a few seconds after you plug it in. Unplug and replug until the light stays on steadily, then leave it alone. Most of the time you'll come back to a restored Kindle. If not, go on to step 2. If you still see the same Critical Battery screen after charging, unplug the USB cord, then hold the power slide to the right for at least 20 seconds. Release the power slide, then immediately press and hold the Home key for another 30 - 45 seconds. Once the Kindle's screen begins to flash, release the Home key. The eReader will boot to recovery mode. To continue, press and hold the R key until the screen flashes again. After the device is finished rebooting, you may see the Critical Battery screen once more. If so, plug in the USB cord and wait for the Kindle to return to the Home screen. - See more at: http://www.laptopmag.com/articles/kindle-critical-battery-error#sthash.Rtxwp4El.dpuf
Usually a reset does the trick. With the Kindle turned off, hold down the power button for 15 seconds. This will reboot the unit and should reset the settings which sometimes go out of sync like a PC does at times when the drivers don't start.
Your tablet may need its battery calibrating. To do this run your tablet until it turns itself off, this will ensure that there is no charge left in the battery. Then leave it on charge until the battery is full. Normal battery use on modern devices like tablets and phones should be between 25-75%, with a calibration once every 3-6 months to ensure a good battery lifespan. If this solution does not work you may need to replace the battery.
It ispossible that sometimes the battery takes a longer time to charge if the voltage of the adapter is low. So after the battery is fully discharged , you must allow the charger to be connected overnight. If the battery does not charge fully then the battery and the adaptor must be cross checked in another unit.
If under warranty you must claim for replacement.
