How to mod OtterBox Defender case for Dell Streak 4800mAh extended battery

Streak-mugen-case-mod (1)

StreakSmart reader Gene S. wasn't going to let anything stop him from buying the $130 Mugen Power 4800mAh extended battery for his Dell Streak. Not the price, not the thickness, not the likelihood that its stated capacity is inaccurate, and certainly not the fact that there aren't any cases on the market made for it.

Because who needs a case specifically made for the extended battery when Gene S. can just make his own? And with the help of his OtterBox Defender Series Case (review here) and a few tools, that's exactly what he did.

Want to do it for your Dell Streak too?

1. Insert the Mugen battery into the Streak's battery compartment and attach the back cover replacement.

2. Place the Streak's original battery cover on the back half of the OtterBox Defender plastic hard case. Line up the edge of the battery cover with the speaker opening of the OtterBox case.

3. Scribe with an Xacto knife or sharp blade.

4. Use a rotary tool to cut out the opening.

5. Put the Streak into the OtterBox Defender hard case. The Mugen battery willl fit perfectly through the new cutout.

6. Stretch the OtterBox Defender silicone skin over the hard case. It will be a tight fit.

If some of the silicone comes out of place (and it probably will after a few days), use double-sided tape to secure it.

Note: This modded case is not compatible with the holster/belt clip that comes with the OtterBox Defender case (unless you mod it too, of course).

Thanks, Gene S.!

    Why would the belt clip not be compatible? I understand you couldn’t place the phone in the clip with the screen out, but why not screen facing in? This is how I normally carry my streak…

    Funny! I literally did this with the Otterbox Impact case I won from StreakSmart like 3 months ago (in terms of cutting a hole with an Xacto knife for it to fit over my Mugen 4800MAh battery). Looks/works great, too! Totally worth it for anybody who has both, IMO.

    Now if only I can find a way to saw off that “Camera Side” BS… lol

  • What about rubbing the “Camera Slide” with some type of solvent?

    You could rubber cement the extra silicone (for a firm, yet removable bond), which you removed from the impact case, to the back of the battery. This would cover the “Camera Side” label, provide added protection to the battery, and maintain some visual continuity.

    I’ve thought of this but unfortunately it looks really weird. I’ve also tried nail polish remover, rubbing alcohol, and sandpaper to no avail (on the extra back they gave me, of course, not the one I use!).

    That looks like silk screen. I used to remove silk screened lettering off by dabbing it with “Goof Off”, wait a while. Apply scotch tape over it with a length longer than the lettering. Smooth the tape down real good with your fingernail and then pull off the tape real fast (like some people do when removing a bandaid). That usually took care of it. If not, a ver sharp safety razor blade can be used to remove the lettering. By the way, I too carry my Streak with the screen facing inward on my Otter Defender belt clip to protect the screen.

  • A swiss army knife is the best tool here. Based from my experience on changing them.
