Extended Battery Question

[delock]

Hello,

I have some general questions regarding extended batteries.

On ebay I see alot of 5200 and 5000 mah for less then 30 dollars compare to the sedio or mugen for 80 plus.

What is the main difference between these batteries?

I ride motorcycle so it's easier for me to carry one or two extended batteries when I'm on the rode.

What is the main difference between these batteries?

Some batteries are more prone to catching fire, and/or not performing to power rating, while others have a proven performance and reliability record.

FWIW, I'm sticking with Seidio/Mugen.
