biggest extended battery you can get that fits perfectly?

---

Decided that instead of an upgrade to my phone, a new battery will eek out some more life from this one. What's the biggest capacity battery that has ZERO size issues fitting in the mogul? It's a Sprint model if that matters.

Thanks!

Fits perfectly? Do you mean no extended case?

biggest mah battery

They also have the most powerfull one, 3600mah and that comes with a new battery door.

Kind of expensive IMHO. I would go on ebay (like I did) and buy one there for 10 - 15 bucks depending on which one. Make sure it states 'new' and gives the mah rating. some batteries say bigger capacity but don't tell you anything about the rating.... There are 3000 mah extended with a door for 12.99 free shipping. Even the label on the battery is the same as OEM except the actual logo....

yeah 1 already buy extended battery the price around 12 usd, shipped from Hongkong.
i think the battery capacity not 3000mah (even in spec said so) i just feel little enhancement from my previous battery

maybe if you want to buy extended battery, try to buy mugen the original one.

For posterity I wanted to point some readers to batteryboss.org

Reviews batteries and there are a lot of scammers out there.
