DEWALT20V MAX 5 Ah Lithium Ion Battery (DCB205)

Holds a charge for a 3-4 month's without use so far. Quick charging time on the DeWalt brand charger.Using a battery adapter for a cheap HF 3/8 driver and 1/2 in impact it works well. Lots of power to make those sparks fly out the sides of the tools lol.Overall, Great purchase.Came in what appeared to be legitimate DeWalt packaging.

Good battery. The price was just right. It works well with with all my DeWalt tools. Keeps a good charge. Not to heavy. Power is there. Design is right. Fit is good.

I had to buy this for my DeWalt fan, for baseball. It charges in a few hours and holds that charge for quite a while. I used it at a 3-day tournament recently, and it held up quite nicely, only requiring a bit more charge at the end of the second day (just to be sure). And, it turns out, I also needed this same battery for the DeWalt weed wacker I just got, so that's a bonus. The battery is bulky and colorful enough that it's easy to spot in a sea of tools and sports equipment. For its versatility across a wide range of tools, the price is high but easily worth it.

Battery works great, good longevity on the job site

Pros:Long battery life, even with heavy toolsCharges quickly with DEWALT chargersSecure fit, doesn’t wiggle or slipDurable outer shellCons:Heavy compared to smaller batteriesHigher price, but worth itWould I buy this again? Absolutely — it’s a beast for any cordless tool.

The 5Ah deWalt battery is currently offered by Amazon at half price. This is great except that you have to be prepared that the battery may not be able to charge. I have a variety of deWalt tools (and I try to expand my collection). My older tools are 18V which I converted to 20V with deWalt's 18-to-20 V converter. (See my related review.) A few of my 18V batteries failed soon after purchase. They worked well initially but within a month they were useless. I was too lazy to complain or exchange so I just took the loss. Recently I bought a 5Ah battery from Amazon. This was the first time I bought the 5Ah; all my other batteries came with the tools and they were lower rated. However, this battery would not charge at all. The chargers (more than one) were all indicating that it was was fully charged. Eventually, I realized that the battery charging pins were not engaging correctly with the charger pins. This time I requested an exchange that Amazon did without delays. The replacement actually is working well. Only time will show how long it will last. The strange thing is that, in one of the company flyers, it is mentioned that deWalt cannot guarantee that all their batteries work well although they try to achieve excellence. I think this is a deWalt's way to tell customer's that they are fully aware about the problems of their batteries. From my point of view --- a loyal customer to deWalt --- this is very disheartening. And I am not alone; many other customers report it (as can be also verified by reading reviews on Amazon). Whatever the problem is with the production line, it should have been fixed and not be allowed to continue.

This is an actual DeWalt battery. We checked at several other stores and they were so much more. It was delivered fast and brand new. We’re very happy with his purchase!

A great batteryHolds a charge wellI would purchase again
