Be careful when purchasing this battery. I purchased with the Dewalt DCD791P1 (Brushless XR 20v drill/driver). This battery was listed on HD's site as option. The battery has the same model number as the battery that came with the drill, but did not seat properly on the charger and lock in place. The pin design on this battery was different than the battery that came with the drill. It would not charge at all because the design differences. Date codes on both drill battery and this battery were both 2020. The drill battery has a set of 6 independent slots for the pins in the middle (picture). The battery that HD had for this one has 5 taller slots like the 2 outer ones in my picture. Another indicator is the black piece in the grooved area. Battery supplied with drill is as shown, but the battery I received was all yellow.

    This was a necessary purchase while doing disaster relief in Puerto Rico. Having the ability to preview the store inventory and therefore not face travel woes with the battery was nice. One battery this size lasts for a long time either in my circular saw or reciprocating saw. Thank you DW!! Dave

    Extended Use 20 volt battery
    I bought my drill about 2 yrs ago, it came with 2 or 3 AH batteries. They do last very well. I charged this 5 Ah battery and put it to the test drilling 3/8" holes in 1/4" metal brackets i had made for a boat project. The battery lasted noticeably longer than my other batteries before losing power. I charge it backup with the same charger used for the other batteries. Wish i have a pair of these!

    For the Big Jobs!
    This DeWalt 20 volt Max battery pack is really great for the "big jobs". This 5 amp hour (ah) batteru really works well in my Circular Saw and Impact Driver for heavy duty use...cutting framing lumber and plywood and installing lag bolts. It hold up to a good 1/2 day of fairly heavy use in these tools. It has a nice charge indicator light to let you know the charge left. I usually just charge it up during lunch time and then work the rest of the day. It has a number of other features like "no memory and virtually no self discharge". It's very light weight compared to my old 18 volt batteries at 1.4 lbs. It also comes with a 3 year FREE service contract. This is a great battery for the PRO and serious DIYer.

    Very Powerful Battery
    These XR tools are great, and if you need the extra capacity, then this is the battery for you. I got this one to use in my hedge clipper since it is the recommended battery for that tool. Capacity is great, I can trim every shrub in my yard (about 30) on one charge and still have plenty left. I especially like the fuel gauge on the battery so I can instantly tell the charge state before I start working. I would recommend this battery highly.

                            Battery life is awful
                            The battery doesn’t last long at all. Using it on my sawzall it will last about 15-20 cuts so maybe 30 minutes max run time.
