i need a new battery for my phone but i dont know what battery goes to this phone. i went to the metro pcs website and i found this battery: Samsung Admire 4G Battery
SKU:EB535163LAGSTA
39$


but then i looked for the phone a looked at the accessories for it and saw only this battery:Samsung Galaxy S Lightray 4G & Admire Battery
SKU:BAT1121
29$

the batteries both look different and the prices are so different i dont know what battery to get. how do i know which battery goes specifically for this phone?

Okay what you do is go to metropcs website and go to admire not the admire 4g. Two different phones. Once at the admire find the accessories link and you can find the right battery for the phone the sch-r720 battery is what you are looking for
