Solved! Help! My battery won't hold a charge

[OnnMyOwn]

My Android Tablets battery is dying. No repair shop will fix it & I don't have the skills to fix/replace it. Someone suggested attaching an external battery to the micro usb- My question is Will it damage my tablet if I attach a 3300 battery to my tablet which is 2100 or is just the voltage I should be concerned with-Does that have to be the same? Please respond-Thank you

I am guessing you are talking about the capacity of the battery with that "3300" number. No it won't damage anything, that is just how large the battery is.
