DEWALT DC9071 XRP 12-Volt 2.4 Amp Hour NiCd Battery

I owned an old DeWalt drill that did not have the extended run batteries and apparently, a charger that kept them in shape. After owning this drill for several years, it, the batteries and charger were stolen. Based on the wonderful service from this old drill and its' batteries, I purchased a new drill w/XR batteries and charger.

The batteries worked great when new, but quickly degenerated and were both dead in a little over a year. I wrote a letter of complaint to DeWalt and they replaced the whole thing. The replacement batteries also quickly degenerated and in less than a year one of the replacement batteries failed and a couple of months later the other one was completly dead.

I suspect it is not the fault of the batteries. but the charger. On the old drill/charger, I could leave the battery in the charger and it would be ready to go when needed. When the new battery was left in the charger, it was always dead when I needed it.

I imagine that if you used these in your job...Read more

Update 12/22/08 still performing well!

Used to cost $60 now selling for $50.

Purchased my first to replace the originals provided with the 12v XRP 1/2 drill/driver. This battery is better constructed and delivers good power for a long time.The original batteries lasted about a year and a half. The jury is no longer out on this unit. I just purchased my second unit. If you use your tools everyday - buy it - you'll like it. For someone who does not use their tools everyday it may be more cost effective to buy the DW-1214's at $28.00 per. So far the 12v XRP drill/drivers have remained unchanged so your batteries will still have value when your drill wears out.

This is the first serviceable battery I have seen from Dewalt; it is screwed together rather than glued. The packaging states that the battery has a 2 year, free service guarantee, which implies that the internal batteries can be replaced within 2 years for only the cost of parts...Read more

I bought an extra one for my saw and drill combo to avoid the dead battery blues. With a third battery, I can always have one in the charger.

This battery will drive about 100 2-1/2" screws on a single charge. I can generally get a few hours in before I need to recharge. The charge power stays pretty consistent down to the last few screws. It dies rather quickly, once the depletion becomes noticable. It seems to hold a charge better than the ones that were shipped with my set a few years ago. I have upgraded to a "tune-up mode" charger also, which is superior to the old charger with any battery.

Whether you are adding to or replacing your battery collection, one of these will do the job!
