How may I obtain a replacement battery?

[rfdillon]

Folks, my Galaxy 7" sch 1800 tablet's battery only last ~ 40 minutes. I would like to purchase and replace the battery but am having a tough time finding one. Does anyone have a good source for replacement batteries for this device? Anyone else suffering with low battery life? Thanks so very much in advance for your help!
