I bought these 3 amp hour batteries and was surprised to find that these batteries do have a fuel gauge, before I made this purchase, I had thought that only the 4 and 5 amp hour batteries had the fuel gauge.
I bought these 3 amp hour batteries along with a DeWalt combo that does come with the 4 amp hour batteries. Upon lifting the package including two of the 3 amp hour batteries, it was so heavy that I figured, these 3 amp hour batteries could not be much lighter than the 4 amp hour batteries.
I have a digital scale that I use to weigh out part A and part B of epoxies, so I pulled it out and I weighed both batteries. I was completely surprised to find that there is not much of a weight difference.
On my digital scale, the 4 amp hour battery weighs 22.32 ounces, and the 3 amp hour battery weighs 21.87 ounces. The 3 amp hour battery weighs only .45 ounces less than the 4 amp hour battery.
This is not much of a weight difference at all, less than a half of an ounce. This is good to know, because I am sure that many DeWalt uses have probably bought the 3 amp hour battery over the 4 amp battery thinking that they would be carrying around less weight, and if it were known that the 3 amp hour battery weighs almost the same as the 4 amp hour, then most people might choose the 4 amp hour battery knowing this.
Who would want to carry around almost the same weight and have an entire amp hour less of capacity?
This having been said, I am sure that DeWalt has more than one manufacturer that makes their batteries for them, and there is most likely a fluctuation in the weight of batteries from one manufacturer to the next, and because of this, different batches of batteries might have a greater weight difference between the 3 amp and 4 amp hour batteries.
Aside from the weight situation, these are quality DeWalt batteries as is expected.
I had read a previous review that said these batteries are only so so and are fragile, I wonder how anyone would say such a thing with no further explanation of how, because these batteries are made from the usual DeWalt plastics which are impact resistant, and these DeWalt batteries are made with plenty thick of plastic, because of this it seems like that review which claimed these batteries are fragile, might have been a false review created by a competitor.
Pros: Durable, Long-Lasting
