Stays charged longer

11 September 2013


I purchased the 1800mAh battery because the original battery that comes with the Casio G'zOne Commando is too weak and dies halfway through the day or might make it to the end of the day. Now my phone makes it to the end of the day with no problem.



21 August 2013


The battery gives me almost 2 days without a charge SO FAR.
If I keep data, GPS and wi-fi on it easily gives me 24 hours with heavy usage.
I'm just happy to have morning to night with no problems.

Worth the expense

Great battery

Have had this battery for a month now. 3 days go by before I have to charge it. I like it.


Better than expected

6 April 2012


According to the numbers this battery has about 23% extra capacity over the OEM battery. I would have been satisfied with that 23%. Instead I got about 50% longer life out of my phone. Either this battery is more than the advertised 1800mAh or the OEM is less than 1460. Otherwise the numbers just don't add up. Either way, you come out on top with the Mugen battery.


Great battery

Hard to believe that only 400mh makes such a big difference. This battery last at least 3 times longer. Thanks.

I purchased the Mugan Power 1800mAh Extended Battery for Verizon Casio G'zOne Commando.It was money well spent.


Quality for the money

24 January 2012


I purchased my phone for the ruggedness. I am a firefighter and use the phone for the texting of dispatches and mapping with GPS. This along with using it for calls and texting to family and friends sucked the life out of the factory battery. It lasted about 6 hrs before needing charging After purchasing the Mugen battery and following the directions for charging, I can get up to 24 hrs out of the phone. I have recommended purchasing this battery to all my friends that also have the Casio Commando.
