![]() The MAX version of the Dewalt batteries is the older design, which the XR improves on. While the 4.0 Ah MAX Compact battery retails for around $98, the XR 4.0 Ah equivalent can be found for less than $90. Of course, you would expect this extra performance to come at a cost, but surprisingly not. The only difference is that the XR version lasts longer. The MAX and XR batteries are compatible by keeping the dimensions similar and retaining the same connection system. The power increase has been achieved through improved technology rather than increasing the capacity of the existing battery. The Compact version is two inches smaller in height and length and 0.3 pounds lighter than the XR version. However, there are 20V MAX Compact versions, which are smaller and lighter than the equivalent XR batteries. Even more surprising is that the XR version is just 0.1 pounds heavier than the MAX version. Surprisingly, considering the 33% extra runtime, the XR version of the battery is only slightly larger than the MAX version. You know the Energizer will last much longer, and that is because of design efficiencies.īuy Dewalt 20V Max XR for 33% longer running time:Ĭheck Price at Amazon Physical size and weight However, thanks to design improvements and increased efficiency in power delivery, the XR batteries will last up to 33% longer than the MAX batteries of the same size.Ī good comparison is between a dollar store battery and an equivalent brand name battery such as Energizer. In a perfect world, two 4Ah batteries will last the same amount of time. In comparison, the MAX range only has 4Ah, 3Ah, 2Ah, and 1.5Ah versions. ![]() The amp hour rating determines how long a battery will last, and the XR range features 10Ah, 8Ah, 6Ah, 5Ah, 4Ah versions. A quick comparison of Dewalt 20V MAX and XR 4Ah Battery Capacity The term XR stands for “Extended Runtime”, and the high-capacity lithium-ion XR batteries give a 33% increase in battery life. The main difference is the additional power the new XR batteries offer. Differences between Dewalt 20V MAX and XR?įirst, it’s good to remember that the MAX and XR batteries and tools are interchangeable, which means whichever battery you buy, it will work with both model ranges. Dewalt has introduced the 20V XR battery range to enhance the already good MAX products, and this article looks at the differences.Īfter reading this article, you will know which type of battery will suit your needs and why. The key to this whole debate might simply be to visit the DeWalt 20V MAX* website-and look for the asterisk.Battery technology is improving all the time and making battery-powered tools more affordable and reliable. ![]() 20V MAX is the Same as 18 Volts Nominal – Proven by DeWalt So before you leave with a bad taste in your mouth about DeWalt or Craftsman power tools, understand that everyone does it somewhere. Jump up to OPE (Outdoor Power Equipment) and we get 40V systems (10 cells) that are taking the place of the 36V platforms of a couple of years ago (we’re looking at you, Husqvarna!). Everyone advertises their 12V line (3 cells), not their 10.8V families. ![]() Putting a nominal voltage on it is a representation of where the battery operates most of the time.įor some reason, 20V Max vs 18V debate only seems to be an issue among these 5 cell group platforms. From a marketing standpoint, being able to put a higher number on the tool makes it seem more powerful. That means 18V high-power tools and 10.8-volt tools. ![]() You’ll find that tools are sold by their nominal voltage in most areas. First, many European countries are more strict about how a company can advertise. This brings up several interesting talking points. ![]()
