Mugen Power Extended 4800mAh Battery for Casio G'zOne Commando 4G LTE w/ Black Door Cover Over 2.5x More Power

GREAT BATTERY, Lasts a long time. Very bulky, sticks out a bit, but worth the convenience of having your battery lasting all day.

This battery will not support the NFC feature of your phone. The included battery cover leaked and defeated the whole reason for a waterproof phone. Nice to have 3 days worth of battery.

Its lasts about 3 times as long. I use my phone for lots of internet and streaming. You still have to manage your open apps, but I get about 2 days out of it. 3 if I just leave the phone to do its job as a phone.

This battery has plenty of power; far better than the original that came with the phone. It is big, and heavy. I usually carry my phone in my front pocket and this battery more or less doubles the weight and the thickness of the phone. It's power is great.

great extended power - now if I can eliminate the power draw it will last even longer!

We only need to charge our phone about once a week , if that much .

Not pretty, but functional... Seems to hold a charge for 20+ hours (but it's only been a week or so)...

My last extended life battery lasted up to two days when it was new. This one lasts only a little over a day,
