I'm curious about the performance differences between the XR, Powerstack, and Flexvolt battery platforms. If I have a 4Ah Flexvolt battery and a 4Ah XR battery, will the Flexvolt run longer under the same load, or do they perform similarly? I'm open to understanding how these batteries differ in terms of energy delivery and efficiency.

Generally, when talking about battery capacity, Ah (amp-hours) measures how long a battery can run at a certain load. If both the Flexvolt and XR batteries are rated at 4Ah, they should run for about the same time if the load stays the same. However, it’s important to note that some batteries can deliver power quicker, which is crucial for more demanding tools. Different technologies, like the Powerstack or Powerpack, can provide higher current delivery more efficiently without increasing size. Very demanding tools might benefit more from these advanced batteries, as they are built to handle higher draw situations.
In real-world applications, performance might differ slightly. High-performance batteries can often last longer with lower power tools due to reduced voltage sag. They’ll maintain their power for longer than standard batteries. However, with high-demand tools, a performance battery might deplete quicker simply because it's able to deliver power more aggressively, while a standard battery might last longer since it isn't working as hard. Take high-powered angle grinders, for example—while a standard battery may last longer, you could achieve more work with a power pack in a shorter time.
Not really—four amp hour batteries should perform similarly in theory. However, factors like temperature play into efficiency. If a battery gets too hot, it’s wasting energy, indicating it’s under strain. So if you have a high draw job, a more robust battery may handle it better, resulting in more usable power, even if both have the same Ah rating!
