FirstPower 3.7Ah 14.4V DW9091 Battery - Compatible with Dewalt 14.4V Battery XRP Cordless Power Tool - Upgraded Ni-MH DC9091 DW9091 DW9094 DE9091 DE9092 DE9038

I bought these after sending back Vanon 4.8Ah hour batteries that didn't fit the DeWalt charger well and one of the batteries gave the "bad battery signal." See my review for that product.These batteries are only 3.7Ah, but I'm very pleased with them. I did not have to force them into the DeWalt charger and pry them back out. I used them for a fairly big job, using 1 1/4" screws to re-attach drywall to a ceiling hung on 70 year-old very hard trusses. This required a lot of energy from the battery, particularly for the last 1/2" of each screw. There were probably something like 150 screws.I used one battery on the first day and the second battery the next day. Neither battery seemed to have lost enough charge to be noticeable.If you have old DeWalt 14.4 volt tools you want to continue using, I recommend these batteries. The price is very reasonable.I would say that DeWalt tools have come a long way over the years, and rather than get new 14.4 batteries, you might want to consider new tools, but for occasional jobs, these batteries will keep your old tools working.

works like the original batteries did

The batteries fit my power drill although it is a bit of a tight fit. So far the charge seems to be holding, which was the problem of my original batteries which failed to hold a charge.

So far working good. We were not able to test batteries at full capacity yet.Batteries came in very good condition and very fast.For now we are happy with the purchase.

Perfect fit! Fit my Dewalt drill and my charger. Came fully charged!

I needed a new battery for an older DeWalt Drill. I was landed on First Power. The 14.4 V battery works well and fits the drill like a glove. The battery appears to hold the charge properly and works. Cant speak to how long it will last but so far so good.

I think the batteries will be fine however the charger will mot accept and charge an actual Dewalt battery that I already have.

Arrived on time, nicely packaged in cardboard box. Battery is slightly taller that original DeWalt drill battery but this may be due to extra amperage than originals. Nevertheless, clips right into my DeWalt drill and runs like a charm. Also fits snugly into the plastic drill case. Too early to tell about durability.
