Can I make it fit in a defender case?
With this battery installed, when I plug in the phone I get a message: "Invalid battery. Your device battery is invalid and cannot be charged. Replace the battery with an original Motorola battery." The battery charging light on the phone does not come on.
The built-in battery charge indicator shows all question marks. Infodroid shows the battery at 90%, but that's what it was reading with the OEM battery. It hasn't changed after being plugged in overnight. The "Battery Left" app is also stuck at 90%. Both Infodroid and Battery Left indicate that the battery voltage is 3789 mV.
It appears that I have a battery that would require an external charger to use. If that's so, I won't bother.
I think I'll leave the battery in until it's discharged and try charging it again. If it doesn't charge, I have a new paperweight.
Mugen also makes a 4000mAh battery, but it's closer to $90 in cost. Their 2000mAh will fit in the OEM stock battery's place and even uses the same door. Of course it has less capacity than the Motorola extended battery and costs $45.
The Seidio extended battery is 3500mAh and costs abut $65.
Personally I feel that the Motorola extended battery at $25 has the best value as it lasts all day (for me at least) and doesn't add that much to size.

I got one of those ebay 4000 battery a while ago for 9.99.
Works great. Unplug at 6AM, still going at bedtime after 10PM.
Left unplugged once and was still going after 4AM and finally killed it about an hour later. Battery monitors don't calibrate correctly but I know I'm near the end at 3000mv. Beats 6-7 hours on standard battery. Going to check on that Verizon 25 dollar special for a more slimmer battery, than this 4000 brick.
Once this eBay battery was discharged, it will not charge in the phone. When I plug in the phone, I get an icon of a battery with a question mark in it.
I have contacted the seller for a refund.
