x2 battery life

[SHO]

Hi,how long is the average run time for the 14.4 X2?My drill is only 1 month old and both batterys seem to last only 30 mins.running a flap wheel.Not to good compared to my old 12 volt Milwaukee.Good thing another one is coming for free in the mail.A little heavier but still should turn out to be a great drill!

Sounds about right for constant use. If it lasts 30 min you will never be without a charged battery as they charge in 30 min. You may want to consider a plug in model for that kind of heavey work
