20V 6.0Ah Replacement Battery Compatible with Dewalt Tools

Bought these exact batteries twice now! First pair are still holding up years later as if they were new. No degradation of capacity or power output from start to finish of use. Work exactly how they should and fit all of my Dewalt tools perfectly like my name brand batteries fit. Will continue to purchase these before I buy anymore name brand batteries. The first set I bought of these 6ah batteries are closer to a name brand 4ah battery, but the second pair I just bought are closer to 5ah name brand. No complaints.

I researched rechargeable batteries and found a YouTube video that evaluated 4 or 5 brands of rechargable batteries. Waitly came out as the best value. I purchased this product as I have a number of Dewalt tools or Dewalt Clone tools (drill, driver, hand held chain saw, led work light, battery operated rachet). I have some of them at my home and some at my lake cabin. I try to keep all batteries charged since I can then switch them out when needed. The lesser amp batteries charge faster (and discharge faster) so if I haven't used the batteries in a while, I always put the lower amp battery on one side of the charger to allow more time for the higher amperage battery that I place on the other side of the charger. I have about 9 Dewalt style batteries by different manufacturers split between my 2 houses. The one battery that did fail is an older Dewalt branded one. The Waitly 6 amp 20 volt battery continues to work well after about 18 months. I'd say I was a medium to high user of the battery tools. I'd buy this Waitley battery again. I also have some Worx battery operated tools (chain saw, handheld chain saw, blower, trimmer, clippers) with 3 worx batteries at each house. I purchased a battery converter (about $20 on Amason) that fits on the Worx tools so as to allow me to attach my Dewalt style batteries if my Worx batteries are all discharged. The blower and the chainsaw drains batteries fairly quickly. As all know the worst thing about battery operated tools is the battery. With this scheme, I have plenty of batteries and could eliminate all Worx batteries in the future (if i live long enough) by simply replacing all the Worx batteries with all Dewalt style batteries. I also have chargers at both locations with ability for each to charge 2 batteries at a time. My system works great for me and provides pretty much constant power from the batteries if I need it. FYI a number of battery converters are available for lots of brands of battery operated tools. Good luck.

These batteries cost half what the brand name charges. They don’t last as long but I think they give about 60 - 70% of the brand name charge life. Having a bunch of these now means I have been able to buy some very nice tools with the advantage of battery powered portability.

I conducted an actual constant-current discharge test on two of these batteries for 3 separate cycles and they consistently measure at 3.9Ah capacity. I chose a fairly easy C/5 rate based on the promised capacity of 6Ah, which is 1.2A. At that rate they should last about 5 hours, but all the discharge cycles ran about 3:15. Termination voltage was 14.5V or 2.9V per cell. As long as you understand that the rating printed on the side is fictional, these batteries are still pretty cost-effective. I had no problems with them fitting and operating all my DeWalt 20Vmax tools normally. I cannot speak to their longevity (yet.) I'm generously giving them 4 stars because quite frankly I expected them to be over-rated for capacity, and I bought them primarily to operate work lights, which they do just fine.

These are good batteries! I bought some 6ah Waitly batteries three years ago, and they still work well. Got more tools and need more batteries, so I ordered another pair. Honestly, they seem to work as well as DeWalt batteries.

When I first got this in the mail I was pretty happy with it. It seemed to work with all the tools that I tested it with and lasted a good amount of time. Unfortunately a little over a month of using it I noticed that it was very difficult to remove from my tools all of a sudden and the plastic where it connected to the tool was becoming deformed. This could be due to some sort of overheating but I don't believe that it's safe to use anymore. Fortunately even though it's outside of the return window Amazon said that they would allow me to ship it back for a refund. I did try to contact the manufacturer directly, but could not find any sort of contact information from them.

This is my second purchase of these batteries. I've had the first pair for a while now and they have been awesome. I bought two more based on the performance of the first pair. They charge relatively quickly using the Dewalt chargers and they run for a more than fair amount of time on my tools. These are 6.0amphr units and deliver excellent performance matching original DeWalt batteries so far. I picked up an adapter and even power my old DeWalt 18volt tools with these. The price is lower than original batteries from DeWalt. They fit all the tools perfectly, and just slide right in and lock up like originals.

Have only had for a short while I experienced no issues project farm rated them as the best aftermarket and the seem to work perfectly in all my old DeWalt tools that needed batteries. Would certainly buy again
