DeWalt recently released their new Power Stack 5 amp hour battery and many people have been wondering whether it will outlast the XR 5 amp hour battery. Some people have suggested that they should last the same amount of time, but we decided to put that theory to the test by using a DeWalt heat gun to take voltage measurements at the beginning and end of each battery. We also tested their run times to see whether there were any significant differences between the two batteries.
Before we begin, it's worth noting that both the Power Stack battery and the XR 5 amp hour battery were brand new and had each undergone three discharges. To start the test, we checked the initial voltage of the Power Stack battery, which started out at 20.57 - not bad. After 16 minutes and 35 seconds, the battery had a resting voltage of 16.35, which started taking a dip at the end. We also noticed that the temperature of the battery was warm to the touch, but not overly hot, with a maximum of 86 degrees.
We then moved on to testing the XR 5 amp hour battery, which had an initial voltage of 20.79. Interestingly, this battery outlasted the Power Stack by only a small amount, with a run time of 17.17 - just over a minute longer than the Power Stack. However, the thermal differences between the batteries were significant. The XR 5 amp hour battery reached temperatures of up to 122 degrees, while the Power Stack only reached temperatures of up to 94 degrees. This is a substantial difference, and one that could impact the battery's overall lifespan.
What's more, we noticed that the Power Stack was able to deliver a higher level of power output for a longer period of time - up to the 15 minute mark - than the XR 5 amp hour battery. The latter gave out all of its power in the first 8 minutes or so. This suggests that while both batteries may have the same capacity, they may not necessarily have the same power output.
Overall, our test revealed some interesting findings. While both batteries may have the same amp hour rating, they are not necessarily equal in terms of their power output or overall lifespan. The Power Stack was able to deliver more consistent power output over a longer period of time, while the XR 5 amp hour battery had a higher thermal output. For those in the market for a new battery, it's worth weighing up these factors before making your final decision.
In the future, it would be interesting to see how both batteries compare against a 6 amp hour battery. While this was just a simple test, we hope that it provides some insight into the differences between the Power Stack and XR 5 amp hour batteries. Let us know your thoughts in the comments below.
