There are a lot of mobile phones on the market today, but it can be impossible to find accessories designed for your particular device if you don’t have an Apple or Samsung product. Mugen Power has an extended Li-ion battery for your phone, if you happen to have the Caterpillar Cat B15Q phone. The standard battery in the Cat B15Q is 2000mAh, but the 4100mAh Extended Battery for Caterpillar B15Q with Battery Door will give you twice that power. This battery will ship on November 21, 2014. It’s $89.50 and can be ordered now from Mugen Power.
