Customer Reviews for DEWALT 20V MAX Premium Lithium-Ion 4.0Ah Battery Pack

I love the lightweight tools and they still pack the torque and power of the generation before them

Great freedom not having a cord or hose!

I am satisfied with this product. The variable speed trigger is a great feature. It allows me to control the flow of grease with ease. First, I lightly press the trigger to verify that the fitting is not clogged, then I press the trigger further to quicken the greasing time. The pressure relief valve is another thing to admire. This is the first time I have used a grease gun with this feature. I must admit, when i saw it purge I thought something went wrong. Then I read the manual and it became clear. The reason it purged was due to the fact that the fitting was clogged. This prevents the grease gun from over working the motor, which increases the longevity of the tool. I like that! The last thing I would like to share is that the bundle was an amazing deal. The bundle included a 4.0A 20V battery! The battery alone is worth $100. There’s was no way I was going to let this opportunity pass. Thank you

Excellent product

Dewalt battery made in many countries including: Japan, Korea, Thailand, Malaysia, and China. The most important are the same price which ever country made. I am so happy that I recieve my two batteries "Made in The Japan"

Just what I needed for extended usage for all my Dewalt cordless tools.

light weight and the additional time between charges is a win-win!

Average tool not what I expected from dewalt tools it did the job but jet I feel the tool lacked the power you expect and expencive first time a dewalt tool did not meet my expectstions.

Great product. And price. Bought 4 batteries for the price of two

Excellent battery lasted long time.

Batteries last a long time

DeWalt is really good brand, no one of the best but pretty close

works as intended- slapped the cup grinder on this baby and the mortar magically disappeared...even taking with it the dust after putting on the dust shroud. Simple, easy to use and put together, easy to hold and if you already have a couple 20v batteries this is a great value addition to use with those batteries.

So powerful

Really reliable tools to use on any work

Wow, this battery last all day. Charge overnight as it takes that much time to do so. If your using an impact driver or drill, it’s very heavy and will wear out your wrist. I use it for jig and circular saw where the extra weight is an asset. Buy two because you can be charging one while using the other.

DeWalt quality at its best!

Good product, but a bit over priced. It's not the home depot's fault they're competitively priced, that's just how dewalt likes to stick it to ya.

It’s a battery. Quite honestly I don’t like that the time it lasts per charge isn’t much better than the one the drill set came with. I love dewalt products but I feel they could last longer per charge

I'm a DYI'ER, I have a circular saw that was given to me by my brother, I like that saw, but for smaller projects or places without electricity this saw cuts very lite weight and very powerful. Since receiving this saw I've used it several times. Great fast cutter.

This saw with a diablo blade is simply the best. Lightweight, powerful and makes accurate cuts with ease. The only downside is that it does not come with a battery. The battery life is satisfactory in my opinion.

Great cordless saw!!...I was ripping through 3/4 mdf with no problem...Fits good in my hand and not too big or heavy...Just make sure you get a big enough battery...I was running it with a 1.3AH and it lasted for about 5 cuts, so get at least a 4.0 AH battery...

Great and simple. It has taken its place in my quick grab tool pile!

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

Great saw, cuts smooth and easy to use! Cut many boards on my Pergola with it no problem!

A bit larger in size than the standard 3, 4 or 5ah batteries. They last noticeably longer than the above mentioned batteries as well. Have been using constantly and consistently for a few months with no noticibly decline in power. I would recommend buying the fan cooled fast charger along with these as a standard charger takes hours to fill these up

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!

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.

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.

I have to keep my eyes on this saw. Everyone at the Habitat builds like to use it. Tough little saw, lightweight. Cuts through all wood even wet frozen wood
