I’m on it. An extended battery can be purchased at www.sprint.com for $69.99 keep in mind pricing is subject to change at anytime. You can also check and see if the store nearest you carries them. To do that please visit, www.sprint.com/storelocator. I would call beforehand to see if they have any in stock and as always you can find one online at third party sites. Let me know if this helps!
