Extended Battery Cases

[kenfb1]

Hi,
Just getting an S4, had to wait for my upgrade date.
Does anyone know what other extended batteries will
fit the Seido extended cases??? I know the Zero 7000
wont fit but the others should, I hope!!
Here's the case;

SEIDIO | ACTIVE Extended Case with Metal Kickstand for Samsung Galaxy S4

I have this kind of case on my S3 and love it!!!!!!

Thanks for any help,
Ken
