20V MAX* XR Battery, 4.0-Ah, 2-Pack (DCB204-2), Black

Light weight and Powerful. So much better than the old NiCd batteries! These are the 4.0Ah batteries, and not to mention there strengths (associated with Li-ion batteries), they do last for a very, very long time, while under a constant heavy work load. When I compare the same work I did with a older DeWalt hammer drill and the 18v XRP NiCd battery, with the new DeWalt DCD995 20V hammer drill , and just 1 of these DCB204 - 4.0Ah "Premium" battery, it's a complete NO contest! The new Li-ion battery from DeWalt last so much longer, I'm talking a full work day, & more! I just love these Li-ion battery packs! As said in another review, you can get these packs in varying Ah capacities. 1.5Ah, 2.0Ah, 3.0Ah, 4.0Ah Before, I would need to change batteries usually twice a day, with the old 18v NiCd batteries and drill. Now I can work for more than a full day with a single battery. So to me, thats one hell of a battery! These light weight but powerful batteries also help with daily fatigue! I'm just so use to my old 18v hammer drill and battery weighing so much, and now this new combination of the DCD995 hammer drill , and the DCB204 - 4.0Ah battery weigh so little, it's really hard to believe you can do so much work with just one of these batteries. But you can!!! & they are amazing! I've been waiting a long time for DeWalt to come out with Li-ion powered tools. I've been doing rough and finish carpentry for over 35 years, along with custom cabinetry. This new line of 20V MAX tools they have are all very nice, and both heavy duty, and affordable Now that they've incorporated Li-ion batteries for power, they will be able to expand there tool line even more. Even though other companies started using them sooner, I'm glad DeWalt took there time! It shows in the tools quality build, and there tools performance! For those of you that are unfamiliar with the advantages of Li-ion chemistry over NiCd & NiMH, please use your favorite search engine, and read for yourselves. There is plenty of good information online for you! I do see 1 or 2 people complaining about Li-ion batteries not performing as good as the older NiCd batteries, and truthfully, those people have NO facts to back up there statements. Li-ion batteries are a Very slow self drain, to NO self drain battery, meaning they keep there charge for a very long time! They have superior storage capacity, and integrated circuitry, to control & regulate, high output voltage and current, over heating, and over charging. There is no more memory effect, like there is in NiCd batteries. They are very safe to use (today), with there built in IC's If these are on par with some of the best Li-ion batteries made today, they should be able to be recharged up to 500 times, and possibly more. I'm not sure what DeWalt says on this. Though all batteries suffer, when used in cold weather, (lower output & performance), Li-ion batteries still out perform other batteries, in both work load & work time. In other words, you couldn't ask for a better battery to use out in the cold! You can find many fact based web sites on this as well. One last thing, both these new line of 20V MAX tools, and these new line of 20 volt batteries get good reviews and ratings from 99% of buyers, so when you do read one of those unfounded reviews saying these are not good tools, please just do your own homework and fact find for yourself, in the end, you'll be glad you did! Professional Quality Tools & Batteries, I Highly Recommended!!!

Weird, Ordered 4 Ah, received 4 Ah. Anyway the 4Ah seems to be the best balance between weight and longevity. The 2Ah don't last long in anything but the drill. Grinder, blower, sander go through a 2Ah fast. The %Ah and 6Ah are pretty heavy holding onto for any length of time. That said. Love the 20V Dewalt tools and batteries Would recommend.

LONG STORY SHORT: I am so glad I bought these. They were more reasonably priced than the ones on SALE at the "Orange Hardware Store" (I got this 2 pack for $89.99). Seems to me like they are an older year/older model, but they work great. Current price at time of writing is $105 for the pair, or $59.55 for a single one. Even at $105 it's worth it. **THESE ARE CURRENTLY $129 at the Orange Store** PROS: -Did a little research (not a ton) and seems as though this battery not only has a longer battery LIFE than the 1.5ah that comes with many kits...but it also packs more power. Makes sense, and it definitely feels like it actually does. My saw seems to cut better through thicker stuff, sander seems more powerful, as does the drill, and impact driver. I'm sure there's science behind it, but I don't know it. -Great price! The 20V MAX lithium-ion battery outperforms every dewalt battery that came before it and that's saying a lot. Get long-lasting power and prolonged life from this 4ah battery that weighs just 1.42 lbs. Each battery has a built-in charge meter so you know how much power remains. Dewalt delivers huge value with this multi-pack, priced only marginally higher than a single device. HIGHLIGHTS: Includes: (2) 20V MAX high-capacity lithium-ion batteries Compatible with all 20V Max lithium-ion chargers and power tools (sold separately) Batteries maintain charge when not in use Compatible with the entire line of 20V Max tools CONS: -You can get lighter 4ah batteries in Power Stack form, but they are more expensive. CONCLUSION: Buy. I recommend them. They work with all my Dewalt 20V tools, hold a charge well, have a lot of power, last longer than the ones that come in a kit.

Good price. I use these daily at work and they are still holding charge like new.

This DEWALT 20V MAX 4 Ah Lithium Ion Battery 2-Pack arrived on time and well packaged. I've used these two batteries several times now in my DEWALT cordless leaf blower, various drills and other DEWALT tools. The difference in weight between these 4Ah batteries and the original 1.x DEWALT batteries was surprisingly not an issue. The 4Ah batteries provide power MUCH longer than my 1.x batteries of course, so it is a time-saver not having to go get another battery, or carry and extra one with me, while using my DEWALT leaf blower to clear the driveway and sidewalks after mowing. I also no longer have to use the 1.x batteries to power my leaf blower, which saves having to constantly charge the 1.x batteries, saving them for use with my cordless drills. I've had these batteries since May 2024 and would recommend them. I would buy this set again.

I recently got the Dewalt M2 drill/driver set and the 20v circular saw, the drill set came with 2 of these 4ah battery packs and they're great so I bought this pair so I had a spare plus one pack for each tool. These 4ah batteries are great - I get really good life out of them using them in the drill, impact driver and circular saw. I've just built a pretty huge 9' x 8' shelving and workbench unit in my garage - from a full charge, I was able to build the whole thing without recharging. Amazing compared to my old 18v powered stuff. Charge time is also faster which is a bonus. The 4ah battery packs from my research offer the best $/ah ratio and these seem to go on sale more often than other sizes so it's worth keeping an eye on the price and grabbing some when the price is right. In case yu're confused by all the different Dewalt 20v battery packs like I was, here's a handy guide illustrating the various models. These 204's are the best bang for the buck! Model - Capacity - Color - Size DCB 200 - 3.0 Ah - 20 Volt standard black - thick DCB 201 - 1.5 Ah - 20 Volt compact black - thin DCB 203 - 2.0 Ah - 20 Volt XR premium yellow - thin DCB 204 - 4.0 Ah - 20 Volt XR premium yellow - thick DCB 205 - 5.0 Ah - 20 Volt XR premium yellow - thick The thin ones are the same size and approximate weight - the thick ones are the same size and approximate weight. So for example at today's current pricing, the 205 5ah XR's ($189) are almost 50% more expensive than these 204's ($131), for only 25% more runtime (1ah per battery). The 2ah XR batteries are half the capacity of these 204's and almost identical price ($129). Therefore in terms of capacity vs $$ these 4.0ah 204's are the best value. The 'fuel' indicators on these batteries are a super useful addition - very handy to be able to see easily how much juice you have left. Really glad I went for these 4ah packs, I was kind of tempted to go for smaller capacity but happy I stuck with these. They add a bit of weight/bulk to your tool (especially noticeable on the drills and the otherwise lightweight 887 impact driver), but this is a minor downside compared to the power and life you get out of them. If you've got Dewalt 20v tools and you need good battery life, grab a pack of these, they're great! PS - to answer the 1 star reviews who bought fakes - always make sure with this kind of item that it says 'ships from and sold by amazon.ca' up top near the price - that's the safest way! If it ships from some unknown seller, avoid it! Hope that helps.

Muy bien

Otimas baterias

Buen producto, el rendimiento es lo que esperaba. Tiempo de trabajo aceptable, lo utilizo con mi rotomartillo DCD796 y me aumento el tiempo de uso un 300% comparada con una bateria de 2 Ah. Supero mis espectativas, y el precio simplemente el mejor.

The pricing on this 2-pack, made the purchase worthwhile, for batteries that have longer run time AND led power-level indicators (unlike 1.5 and 2 AH batteries)
