4Ah batteries won't charge up
[This review was collected as part of a promotion.] I have several DeWalt Li batteries but I have TWO 4Ah batteries that are bad. They never charge up, only 2 lighted bars. Thus, they die quickly. The larger Li batteries all work well, but the smaller ones are of poor quality.

    Love this battery. Its lightweight, powerful and it will hold its charge. The on board battery charge light is a plus. It will help you get the job done with power to spare. This battery makes your tools easier to carry. Its a power house at a more economical size in both weight and size with plenty of power to for your dewalt tools. I would rate this batteries 6 stars if I could.

    I bought this 2.0 Ah battery pack to use with the 18 V to 20 V adapter that I bought for the older 18 V tools I have. It was $30 off of the regular price (new lower price) so I opted to go with this instead of the older 18 V battery which was $40.00 higher ($99.00). I may still buy the older 18 V battery if I find a great price simply because the adapter doesn't fit my 18 V flashlight. In addition, this battery will work with all of the other 20 V tools I have bought recently and can serve as an extra battery. By the way, don't leave the battery in the adapter or it will run down.
