    • Battery charging & charger
Style: Battery
I am writing this review in hopes of clearing up problems with new batteries not charging. I ordered the pair of dewalt 20v 6 amp batteries. upon receiving the batteries they had 1 bar filled on the power indicator. I put them into the charger I already had dcb 115. The lights on the charger indicate they are charged, even though the battery is still showing 1 bar filled. I had the items replaced, they sent a new pair of batteries out. The new batteries had the same problem. one battery in the new pack even had the light for temp activate. even thought they sat in the house for 2 days. I was about to return the batteries and somebody told my it was the charger. Even though they tell you its universal and any charger will work...they wont. Today I purchased the dewalt fast charger DCB118. and the batteries are taking a charge, finally. it only cost me another $95.00 Since they sent a second pair of batteries and all 4 are charging, I guess that makes up for needing to buy another charger. The sellers may want to add that to the description: THAT YOU NEED THE DCB118 FAST CHARGER FOR THESE TO WORK. ... show more

    • Surprisingly effective
Style: Battery
I own 23 Dewalt tools that use these batteries, mostly purchased as bare tools, and 6 of these 6 ah batteries. That includes outdoor equipment like a chainsaw and blower, saws and multi-function tools, and a variety of hand tools like sanders, drills, impact drivers, and lights. Obviously I don't use them all at the same time, so in my view buying the tools and batteries separately is the best bang for the buck, especially when paired with rapid chargers. I love the interchangeability of the 20V max system and these higher-end batteries last quite a while. For example, it only took two of them to use their 12" chainsaw to down a 30 foot tall tree, trim the branches, and cut the big stuff up into firewood. I'm amazed and impressed that I got all that done on just two batteries. So far none of them have died, no matter how old they are, but the price has been coming down over the last few years and I pick up a new pair whenever they go on sale so I'll never run out. ... show more

    • UPDATE: 3 of 4 have died in roughly 2-1/2 years.
Style: Battery
I purchased a pair of these 6AH's in January 23 and another pair in August. I always write the month and year of the purchase of the battery with a Sharpie so I can keep up with the age (I have about 10 batteries in varying AH). About 6 weeks ago, I noticed that one of the 6AH batteries bought in January would only charge to level 2 and would drop immediately when put on a tool. When time permitted, I tried to recharge several times on a Dewalt multi-charger and a single charger, but same result. I finally gave up on dealing with it because I don't have time to for it. My concern is how long will the others last; these aren't cheap. I will probably not buy anymore of these 6AH's until I can feel confident that the one battery was a fluke. UPDATE, 29 AUG 25: Of the two pairs I bought in 2023, only one still works. Allow me to point out, I don't use these batteries all day, everyday for work (I work from a computer all day), but do rotate use regularly as I renovate my shop/office and around the properties projects (they're endless between the chicken coop, large garden and beds, irrigation, the well...). Because of these failures, that I feel are premature considering my moderate use, and the weight, I will not buy these 6AH batteries for general use; I do have some devices that require 6AH, 8AH and 12AH batteries, so I will not be able to completely rid myself of big Dewalt batteries. However, for general use, I've decided to try the 5AH batteries: smaller size, weigh less, less cumbersome, cost less and true, runtime is slightly less. Hope this helps. ... show more
