20V 6.0Ah Replacement Battery DCB206 DCB205 DCB204, 2-Pack Lithium Ion Batteries Compatible with Dewalt 20V Cordless Power Tools DCB205-2 DCB200 DCB180 DCD985B DCD771C2 DCS355D1

I have now owned about a total of 6 of these batteries. I work with a small business that uses Dewalt brand tools to do installations and we need our power tools to make our work efficient.These fit what they say they will fit and these work the way they should work. For the price, there is really no beating it.As far as longevity, it's hard to say. We operate in Phoenix, AZ. I have only really used these thus far in the summertime here, and the excessive heat and sun is no friend to the longevity of anything here. We have had name brand batteries expire, just as one or two of these have.I am still a supporter of "you get what you pay for", and the maufacturer may still be the BEST in this situation, but this product is no failure. You can get FOUR of the equivelant batteries for the price of ONE name brand battery at a big box store.Hands down, absolutely worth the purchse.

This is a MUCH cheaper option than buying the DeWalt brand of big boy battery. In the charger you have to snug it up good to insure good contact for charging - but no problem at all in the DeWalt tools themselves. So far, so good- Much longer lasting the smaller DeWalt batteries and much more amp time. Great for the circular and saws in all DeWalts. I would buy this item again.

Have had these batteries about 3 months. These are well below the price of the Dewalt Batteries and are higher capacity. I have pushed them very hard with discharge over short period and they worked exceptionally well. They do have a delayed charge when having discharged in a rapid manner but just put them on the charger and in about 15 minutes will have cooled and they start their charge. My highest recommendation is that I will buy these again as I need additional ones.

I had just purchased the full DeWalt set from Home Depot my principal reason for this was to cut a 5/8 chain on my Mooring I charged up the DeWalt batteries brand new first usage and they don't do the job both batteries that came with it could not cut halfway through that chain I was pissed called a couple guys I know and one of them told me to get a knock-off batteries so I went online and found the biggest ones I could these ones charge them up and one of the battery cut my chain no problem

As a former research scientist, I felt the need to test out the claims on amp-hours here. It's actually difficult to accurately test the batteries directly, so the only thing to do is to compare their endurance on a constant drain device. I've charged up both these two batteries and a genuine Dewalt 4Ah battery that is also brand new.When comparing the weight, I noticed that these are slightly lighter than the Dewalt, but I'm going to attribute that to the lighter plastic used. The batteries are physically identical in size, and similar enough in weight, that they appear to be physically identical to the 4Ah.To test endurance though, I fully charged both of these plus the Dewalt and connected them to my Dewalt blower running at full speed with the autopilot throttle locked on. I ran both of these batteries and the Dewalt battery until the blower cut off and the battery was showing fully drained.The Dewalt 4Ah ran for 9:48The first of these blue batteries ran for 9:16The second ran for 9:23It seems pretty clear that these are actually 4Ah, if not slightly less. I'm afraid that Amazon needs to change the description, this is not an accurate listing. They may still be a decent deal as 4Ah batteries, but they need to be listed correctly.

These batteries are great. I'm hard on my tools and don't tend to get the full life expectancy out of batteries due to cold weather since I leave them in vehicles/trailers in the cold. About half my daily use tools are 20v and the other half are the older 18v that I have an adapter for to run these batteries. Whenever I get batteries, I've started writing the MM/YY on them so I know which ones are the oldest. I've bought 3 sets of these batteries over the years. Its been my Dewalt branded batteries that will stop holding a charge and I end up replacing them with these. I consider it a success if I can get more than 3 years out of a battery and these have fit that bill. These are on par with the branded version as far as performance but with a much lower cost. I know the branded ones have a year long warranty and that's something to consider but of the 3 sets (6 batteries) I've ordered from this seller, all of them have lasted past the 1 year mark and are still in use today. The oldest set I have is over 3 years old and still going strong.

I was interested in these based on the price of them compared to a 20v, 6 amp hour dewalt battery. I’ve had decent luck with knock offs in the past. These work great. They fit the tools, the dewalt charger I had, and last long. I don’t have a real 6 amp hour battery to compare it to but it lasts very long. Highly Recommend.

We've been using these on our farm for a couple months and so far so good. To use these batteries in our older DeWalt cordless tools we had to purchase the adapter. We used a bench grinder to make the adapter accept these and the DeWalt FlexVolt batteries and everything functions securely, no problems at all.Best thing about these batteries is that they feel like they weigh half, maybe less than half of what the DeWalt 6.0Ah FlexVolt batteries weigh. We were concerned that adding the adapter between the tool and battery would add weight but with these batteries it is actually lighter than the old DeWalt batteries these have replaced.These batteries have the LED charge indicator lights just like the OEM DeWalt batteries. We use the newer charger that came with our first pair of FlexVolt batteries for these. We are no longer purchasing the older DeWalt batteries, we are now using these with the inexpensive adapter on all of our older and newer DeWalt cordless equipment.
