A product and service you can trust

7 June 2014


This battery should be installed in this device from the beginning. You can work whole day long and make calls as long as you like, you need to re-charge it overnight only.

with this outstanding battery , my blackberry bold 9900 become at last , a real tool for me now. The juice last at least 2 or 3 days ( depend at what you do ). the good point ,also , is that you keep NFC with mugen back door. Like I said : expensive, but really good buy.


Excellent, now I can finally focus on my work

Excellent product, the right solution for BlackBerry 9900. It is neither too big not too heavy for this device. It has an excellent buttery cover on the device and a pocket bag which is better than the original from BlackBerry. The service is outstanding.

Extrem lange Betriebsdauer bei kurzer Ladezeit.

Battery is excellent, NFC works perfectly, the back cover is strong and mimics the "rubber" feel of the back, giving it a strong grip.

Battery life has increased to more than 4 days without charging!

It arrived to the United Kingdom in less than a week.

Overall, very satisfied, it's true that you have the weight and size factor, but this battery will turn your bold into the ultimate workhorse, that's perfect if you're a heavy user receiving dozens of emails daily.



Good but HEAVY

The battery was promptly delivered within a week to India.The battery lasts for 2 days compared to old one which last only for half a day. But it is quiet bulky and carrying the phone needs queit an effort. But it a small compromise you can make, if you want use your BB 9900 without power interuptions. Go ahead and buy it!


Excellent product and service.

Mugen should be proud of their service. Item arrived less than 1 week to the UK .
A quality product that means , using Bluetooth and 3G , all my e mails and still have battery power after 4 days.
OK it makes the phone Heavier and Bulkier, but that doesnt matter to me anyway.
Comes complete with battery cover and protective case.
Well done Mugen , Quality product, Quality Service


Finally No more dying battery.

23 November 2012


I bought this battery because I want to use my Blackberry 9900 on the 3G network. I could not do this in the beginning because the battery lasts about 2 hours on the 3G network then the battery gets drained! With this battery i managed to get 32 hours of being in the 3G network! Big improvement from the stock battery. I highly recommend this battery if you are sick and tired of hearing that "Battery too low for radio use" beep.
