Tablet Replacament Battery for GB-S20-3096AS-0100 Papio

hello I have this Android tablet it's about a year and a half old I think it's quite nice to have around for various tasks and especially when you're out traveling it's great what's more we are just browse the Internet things like that however suddenly the best week I've just went downhill will really quickly it used to have reasonable battery life something like four five six hours watching videos and browsing the internet etc but now it will only hold battery for about five minutes before it switches off so I think before I open it and see if we can find anything obvious I have fold inside so I'm no Luis rush man doing component little board repair but we should be able to determine if it's the battery or is the charging circuit or perhaps some kind of protection circuit so let's try open it up and see what we find I have discharged the battery as much as possible before we start taki
