not sure where to put this.... question on cordless drills

hi there,

not sure where to post this question but anyway....

ive been looking at getting a new cordless drill but was wondering what counts when it comes to battery sizes for example. 18v 1.3ah vs 14.4 2.0ah vs. 12v 2.6ah. i know there are three or so different battery technologies, so for this example lets say there both LI-ion.

i think alot of people get miss lead when it comes to cordless drills they see the '18v' stamped on it and think that it will be better because it has more voltage. but is the 14.4 @ 2.0ah not going to store more energy than an 18v 1.3ah? is there any advantage to having an 18volt? does it automatically have more torque? i thought torque came down to the actual motor in the drill not the battery power. can it deliver more energy quicker because it has a higher voltage and so have more power? is there a general formula for working out batterys?

kind regards jason

Hi Jason,

My understanding is the more AH amp hours the battery can hold the better,ie more holes per charge.Voltage does seem to correlate with torque however.
