Dewalt Battery??

Which is the best Dewalt battery?

Ive got 2.6ah batteries but they keep running out really quick

How long have you had the drill and what kind of usage does it get?
I had a problem with my 2.6ah batteries hardly lasting any time at all; turned out the motor was on the fritz.

The capacity of any battery pack deteriorates over time, the length of useful life from the battery depends on how it has been treated during it's lifetime. Your batteries are showing the classic end of life symptoms, of requiring increasingly frequent charging and decreasing run-time between charges.
I believe you have the Dewalt 2.6Ah Ni-Mh batteries.
There are some basic rules to maximise the battery life:
1) Use the battery until the point that the chuck cannot drive the drill or screw-driver bit with sufficient torque to do useful work. Do not recharge the battery at any intermediate state of charge.
2) Immediately the battery has become depleted fully re-charge it in the appropriate charger.
3) Avoid charging the batteries in a Dewalt radio charger, the batteries have a tendency to get extremely hot due to not being charged in free-air, this shortens their life rapidly.
4) At least every 3 charges (ideally every charge) the battery should be given a full charge as normal, but at full charge do not remove the battery from the charger for at least another 4 hours this allows the individual cells in the battery pack to equalise their charge.

Bit late for saving your batteries by the sounds of it.Invest in a new drill with lithium batteries. Usually costs too much to buy batteries.Better off getting new drill as well

I found NICD are Ok but need to be left, as you say, for a period of time after they have been 'fully charged'. The manufacturer recommends that the batteries should be left in the charger for 10 hours every week.
Continual use and charge every day in a never ending cycle screws the battery up very quickly. I believe there are ways (Utube) to rejuvenate the little darlings.

thanks all, can anyone recommend decent drills??

Yeah, Ive got three or four knackered Dewalt NiCD, doesnt help when there is no battery bank on site and some prat unplugs your charger to plug his laptop in.

Im looking towards getting them recelled by a company in Essex,£55 a pop, but 4ah, yep, thats what they say.

Andy 7671, can you let me know the name of the company, that dose the battery re-cell-ing?

thanks
