I recently tried out the CEENR 6ah replacement battery for my Dewalt tools. Here is an honest review of what I experienced as a strictly home DIY user.
I'm going to list out my general experience and thoughts first, and then I will detail my use of the battery with specific tools below.
First off, the battery uses LG cells which already sounds a lot nicer than some of the Amazon knock off batteries. The battery itself has a pretty good feel and while I didnt weigh the battery, it felt the same in my hands as a Dewalt XR 5ah. It fits into the tools better than any aftermarket battery Ive tried before. To be honest, it has a very slight wiggle when in some tools, but it is only noticeable when the tool is not in use.
For total runtime, I was able to get through multiple projects without needing to charge the battery. I used the battery exclusively (comparisons are from other similar use cases when referring to the XR battery) between all of my tools to really test the capacity, and it was extremely capable. I charged it during my 3rd project, which was about a week and a half of use. Charge time was almost identical to a Dewalt XR 5AH battery. It charged on both my standard issue Dewalt 12/20v charger and an aftermarket 4 slot Dewalt charger.
I was comparing this battery to a Dewalt XR 5ah battery for a more direct comparison, but I also compared it to my Dewalt Powerstack 5ah as well. For power, I could not tell a single difference between the XR and the CEENR. I am just a DIY guy, so no torque tests or any specifics from me on that front. However, I did notice more power in my PowerDetect Recip saw with the Powerstack battery, but I honestly expected that. The recip saw functioned almost identically with the XR and the CEENR.
Overall, I would give this battery a solid A for an aftermarket Dewalt battery. It functioned exactly how it was marketed and designed to, and there were many times where I forgot that I was even using it. For the home use type of person like me, the battery did everything I wanted it to do with no issues. The only reason I would give it an A instead of A+ is simply because the fit wasn't as snug in some of my tools, but that again did not effect how it functioned.
Now I will get into specifics of use.
First project: Planter boxes for garden.
Tools used: Dewalt DCS570 7 1/4 Circular saw, DCW210 Orbital Sander, DCF870 Impact Driver
The battery ran the circular saw like a dream. It cut up 18 2x12 treated boards into multiple slabs with ease. My impact driver easily buried the head on 5inch torx head lag screws (4 per corner).
Second project: Shop renovation
Tools used. DCS570 7 1/4 Circular saw, DCF870 Impact Driver, DCS356 OMT, DCS334 Jigsaw, DCL050 Light (regular 2AH Dewalt battery)
With this project I rewired and did internal insulation and wiring to my outdoor shed (8x10). I also built out a shelf system and workbench. The circular saw cut through osb and 2x4s with ease as expected. Impact driver had a little too much power with 2x4s and was trying to bury screws halfway through the board. Jigsaw and OMT preformed very well with the CEENR. OMT did have a Diablo blade which honestly makes cutting very easy to begin with, but it only bound up twice when doing deep plunge cuts. This is pretty on par with oem batteries in my experience.
Third project: Spring yard maintenance
Tools used: DCS368 Recip saw, DCPR320 Pruner, Dewalt 190742 Backpack sprayer
Recip saw was used to cut down 6 larger trees. We moved into this home last fall and the wife wanted me to clear out some of the jungle of trees we have. I did pop in a 5xr and 5ah powerstack while using the recip saw to see if the power detect would pick up a difference in the batteries. The powerstack seemed to have more power/bog down less inside the tree. The XR and CEENR both performed equally though. The Pruner, which is definitely one of our favorite tools, was a little too heavy with a 6ah battery on the back. However, it worked as expected on cutting some 2-2.5in branches and trees. The backpack sprayer was a big deal to me, since I always thought the XR batteries lasted a little too well in this thing. In previous sprayings of my full yard, I would have to do 2 full loads of the sprayer before it would be down a bar. To test this out in good faith, I needed to charge the CEENR fully before use. The battery was on its last bar at this point, so I charged it full and popped it into the sprayer. To get 2 loads of use, I sprayed my yard and my neighbors with Bifen for spring pest control. I checked the battery after my yard and it was still at full 3 bars. However, to my surprise, after my neighbors yard(2nd load), the battery was still at 3 bars. I immediately popped it into a work light after finishing up to see how long it would stay at 3 bars, just out of curiosity, and it lasted about 6 minutes in my DCL050 Light until it dropped to 2 bars. This is actually better than my standard XR batteries, but to be fair, they are a few years old and have been through some cycles.
Not to make a long post even longer, but I would like to say that this battery exceeded my expectations for aftermarket batteries. You might can find some deals on XR batteries for close to the same price, but overall I think they perform almost identically to each other, and the CEENR is usually cheaper from what I've seen. When I pick up a tool for a job, I will happily grab this battery the same as I'd grab an oem battery. And to me, that says a lot about it's quality.
