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 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 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.

So battery’s are great Especially if you are not trying to get rid of the drill and waste your money on a new one these batteries work great but the batteries length of time is not as good as the original dewalt or craftsman product. If you are like me who just using products around the house, fix things and repairs or builds a few things perfect if you’re contractor, you might want invest buy a new drill

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!

Fast and smooth transition. So far batteries doing fine.

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.

I purchased these in July, 2024 and I use it about every 2 months. I wanted to use the drill again in early January, 25 and they were both dead. I recharged both but only used one and recharged that before I put it away. I came to use it in February and they were both dead again. I recharged and used one and then recharged both. Yesterday on March 20, I wanted to use the drill and they are both dead again. In fact the LED light would barely light for less than 30 seconds.They are both junk and I would not consider purchasing this product again.
