EB-BT810ABA EB-BT810ABE Tablet Battery Replacement for Samsung Galaxy Tab S2 9.7" SM-T810 T810X T813 T815 T815C T815X T815Y T817 T817A T817W T817T T817P T817X T817V T818 T818A T818V(3.85V 22.6Wh)

I put this into a Samsung Tab S2 model SM-T813. The fit was a bit tighter than the original battery, and for a few minutes I worried that I would have to send it back. With some care I was able to fit it into its compartment, and it now runs fine. BTW there are two ways to disassemble this model, either removing the screen or removing the back. Removing the screen takes the chance of breaking the screen or bricking your tablet, but if it doesn't brick, it works great. Removing the back takes a significant chance of breaking a couple of mounting tabs, but the tablet will survive. I chose to remove the back. It went great, though I broke a mounting tab. New life to an old tablet.

Excellent deal for a battery that costs $45+ elsewhere. I used a spark plug feeler gauge to pry the back cover off of the tablet and it was relatively easy to replace. Expect some plastic clips to break on a 11 year old device, but there were plenty remaining to reattach the back cover. Battery has undergone only 3-5 charge cycles so far but it lasts significantly longer than the 11 year old battery it replaced. The device I replaced the battery in is an SM-T810 (Galaxy Tab S2 9.7") running lineageOS 20 (Android 13). Still a very capable device.

EDIT: After further investigation it turns out the USB cord used to plug the device in is somehow faulty. I was only able to confirm this using a USB tester. Every time I plugged in the tablet it would show that it was charging, but the battery % would only go up intermittently, then stop. Without the USB tester I would never have known this, especially since the USB cord was less than a few months old. I apologize for the 30+ hours my one star review was up and changed it to 4 stars. Purchased this battery to replace factory original in Galaxy S2 9.7" tablet. Pulling back cover off is difficult, but has little to do with the battery - that is just how it is and if you attempt this yourself you have to have patience. Be extra careful not to ruin the thin ribbon connectors by the right-side buttons. If you do you've bricked your unit. Once I replaced the battery and back cover and turned the tablet on the battery showed 49% charge. Plugged the tablet into it's power brick charger to bring up to full charge - and it steadily rose to 80% just like the original factory battery used to. But then it stopped taking a charge. Pulling back cover off did not reveal a bulging battery - so this means that the battery sent to me is going to die pretty quick and I will have to purchase yet another replacement before that happens. I'm very disappointed that the quality of this purchase is so very low. I do not recommend this battery to others. Unfortunately this is the same battery that is being sold by all the other vendors. If you end up getting a good one then that's awesome - but you take your chances.

Very happy with my products

By our old tablet back to life. It was reasonably easy to replace the battery.

Brittle carry case, should have been shipped in more than a bubble mailer. Hope the fasteners holds up better.

I plugged this battery into my Samsung tab s2, and it would not power up.

From delivery to installation was fairly easy. you tube video showed taking the case off from the back of my Samsung Tab S2 very easy. Battery was an exact fit and worked very well. The prior battery was causing the operating system into a continuous reboot cycle and this resolved my issue. It came up normally as expected after the replacement battery was installed.

Batteria sostitutiva per il mio Galaxy tab S2 modello SM-T815 , con questa batteria ho potuto riportare alla vita il mio vecchio tablet . La sostituzione della batteria non è stata difficile in se ci sono solo delle vittime ed un cavetto di connessione. La difficolta maggiore e stata nel rimuovere la copertura della batteria , ma ricorrendo a video dimostrativi su YouTube ed a un plettro per chitarra sono riuscito a rimuoverla senza romperla.

Super Ware
