Update: Sold Out.

Amazon has the ZeroLemon Samsung Galaxy S III 7000mAh Extended Battery for only $24. This case will add over 4 days of battery life to your Galaxy but unfortunately will also add a bit of bulk, a small price to pay to keep your smartphone rocking for days. ¬†ZeroLemon boasts that this is the world’s largest capacity battery pack for the Galaxy S3.

Use promo code “MA2HRRC7” to slash $10.20 off the retail price of $34 bringing your total down to just $24.
