Review: Amazing Li-ion Batteries, Powerful & Lightweight!!! - 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!!!

## Questions & Answers

**Q: Are these replacement for DCB201 batteries?**
A: No. DCB201 stands for 1 Amp/Hour.This is 204, as in 4 Amp/Hour.It is a bigger battery, it lasts much longer. It is also quite larger, so it weighs more. 201 is good for light work with a drill. 204 is what you need to operate the saws, the grinder. It is also very good for heavy duty with the drills, if you don't mind the extra weight.

**Q: In the item description it says "Package Quantity -1"  I assume this to be a mis-print?**
A: it is 1 package of 2 batteries.  Have had mine for over a year now under hard use,  still working Great!

**Q: Battery shipment, why i can not shipped 20v battery alone from amazon to any place in israel?**
A: because shipping regulations prevent legally shipping lithium ion batteries by plane when they are not shipped in or with equipment. They also would still need to be under 100 what hours per battery then.

**Q: What are the differences dewalt dcb204-2 dcb205-2 batteries?**
A: Each amp hour that you increase, the runtime will be 20-25% greater. The DCB204 is a 4.0 AH battery and the DCB205 is a 5.0 AH battery.
