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!!!

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.

Tried the other cheaper batteries. They are not reliable. They keep shutting off (thermal out). The Dewalt batteries work the way they are suppose to.

OK, the batteries were good quality. The charges didn’t stay as long as I expected them to, but I would buy them again.

These batteries are amazing. I bought them in a combo because it's always useful to have a spare charged while you use the other, and they've really lasted a long time. I use them with my DEWALT drill, screwdriver, and circular saw, and the battery life is excellent. They're 5.0 Ah, so they last much longer than lower-capacity ones.

Why did you pick this product vs others?: I have many Dewalt wireless tool and find the Five-Amp-Hour battery the best option. When you look at the cost, available power this battery balances both. I use the Five-Amp-Hour batteries on most projects because of this balance, especially on extended projects.
