2PACK 6.0Ah DCB205 Battery Replacement for Dewalt 20V Battery Max XR Lithium ion DCB204 DCB206 DCB205-2 DCB200 DCB180 DCD985B DCD771C2 DCS355D1 DCD790B

I conducted my own test of these batteries. I first timed one 4Ah and one 5Ah genuine Dewalt battery. To prepare for the test of the Havpower batteries, I completely drained and recharged them 3 times before the final time test. The tool I used for all battery tests was the Dewalt DCBL720 blower. Here are the results:Dewalt 4Ah - 14 min. 16 sec.Dewalt 5Ah - 17 min. 49 sec.Havpower (#1) 6Ah - 14 min. 30 sec.Havpower (#2) 6Ah - 14 min. 42 sec.As you can see, these batteries provided only a few more seconds of run time than the Dewalt 4Ah battery. It seems Havpower must be aware of their performance so labeling these as 6Ah batteries could be construed by some people as false advertising. It also could be that I received faulty batteries but my feeling is that these are probably typical of what other people receive. However, the price for two of these batteries is less than the price for one Dewalt, so I got about 29 total minutes of run time compared to almost 18 minutes for the one Dewalt 5Ah battery. It seems any 6Ah battery should run in this blower for at least 21 to 22 minutes based on the above testing times. After running all four batteries in the blower, they all got warm/hot about the same, so no issues there. The batteries fit my DCB115 charger although I had to give them a little harder push to make them snap in to position. I think the spring connectors may be a little stiffer than the Dewalts. But once firmly in place, they charged about the same as the Dewalts. I gave them 3 stars because they are obviously not as good as the Dewalt but for the price, they are a fairly good value. As far as how long they will last, it remains to be seen. Only time will tell. If they fail prematurely, I will adjust my star rating. I'll leave it up to you to determine if they are worth buying.Updated 7/6/20 - One of the batteries recently failed and wouldn't charge. I would place it on the charger and the light would blink for a while. When the light turned solid, I took it off the charger but the indicator lights only showed 1 light and the tool would only run for a couple of minutes at a slower speed, then stop. Knowing I had a 1 year warranty, I contacted Havpower and they immediately sent me 2 replacement batteries, no questions asked. I raised my star rating from 3 to 4 stars because of their quick response, honoring their warranty and excellent customer service.

purchased 02/20. one battery has already failed. will not charge. No provision to contact seller. Amazon refunded purchase, but with a restocking fee. What??? restocking? how are they going to restock failed battery? $11.40.

I ordered 2 20V Lithium batteries. I put one in my Dewalt 20V hammer drill and the other in my Dewalt 20V Circular saw. The batteries burned up the motors in both tools in less than 30 seconds.20 Volt BATTERY 1 tested at 67.9 volts20 Volt BATTERY 2 tested at 69.8 volts

I was areally supportive of these batteries until I found that one has failed and won't recharge at all. The return period ended in July and it failed in October 21. Avoid these batteries! The charge doesn't last as long as a DeWalt genuine battery and of two ordered one has already failed. Stick with the originals!

These are aftermarket Lithium-Ion Batteries (2) that fit Dewalt 20V cordless tool, rated at 6 Amps they have plenty of power for long life between charges. I've been very pleased with run times and honestly don't see a disadvantage compared to Factory DeWalt Batteries, the best thing is the low price compared to DeWalt Batteries. They charge just fine in the factory DeWalt 20v charger and fit each tool perfectly. A great value for DeWalt Tool users.

I use these in my Dewalt tools around the house. I am not using them in a professional trade or for considerable amounts of time. I own 4 of these batteries and use them on my sawzall and angle grinder most of the time. They work fine and have enough power to accomplish most of my needs without a battery switch. When they are dead, they recharge pretty quickly on the Dewalt charger, and seem to last about the same amount of time on recharges. I used two of these batteries the other day during a full day of welding and angle grinding. It was not continuous grinding of course, but at the same time, I didn't feel concerned about having to continually swap batteries either.

worked well, then kuput!! charged but only worked a few minutes in blower. sent em back. also neither me or amazon chat rep could contact manufactured. hummm...

Better than original. Think I will buy another pair. Runs my dewalt saw great. Made at least 20 full lenght cuts on plywood and still had a charge. My orignal would make 2 or 3 max

Good
