DEWALT DCB609-2 20V/60V MAX FLEXVOLT 9Ah Battery, Pack of 2

I recently purchased the DEWALT FLEXVOLT 20V/60V MAX 9.0-Ah Batteries (DCB609-2) and have been thoroughly impressed with their performance. This two-pack set is a game-changer for anyone using DEWALT’s 20V, 60V, or even 120V MAX tools.#### Performance and VersatilityThese batteries feature innovative dual-voltage technology, automatically switching between 20V and 60V, depending on the tool. This makes them incredibly versatile, compatible with a wide range of DEWALT tools. In 20V tools, they offer up to **6 times the runtime** compared to standard 1.5 Ah batteries, making them perfect for extended projects without frequent recharges​:citation[oaicite:8]{index=8}​​:citation[oaicite:7]{index=7}​.#### Power and RuntimeEach battery has a substantial **9.0-Ah capacity**, providing ample power for high-demand tools. I used these with my cordless circular saw and was able to tackle tough, high-load applications without any hiccups. The runtime is impressive; during a recent project involving extensive cutting, a single charge lasted all day, which significantly boosted my productivity​:citation[oaicite:6]{index=6}​​:citation[oaicite:5]{index=5}​.#### Design and FeaturesThese batteries come with an LED state-of-charge indicator, allowing me to quickly check the battery levels at a glance. This feature helps avoid unexpected interruptions during work, ensuring I can plan recharges during natural breaks in my projects​:citation[oaicite:4]{index=4}​. The batteries also run cooler compared to similar high-capacity models from competitors, reducing the risk of overheating during intense tasks​:citation[oaicite:3]{index=3}​.#### Durability and WarrantyThe build quality is robust, typical of DEWALT’s standards. They feel solid and well-made, capable of withstanding the rigors of a busy job site. Additionally, the batteries are covered by a **3-year limited warranty**, along with a 1-year free service agreement and a 90-day satisfaction guarantee, giving me peace of mind regarding my investment​:citation[oaicite:2]{index=2}​​:citation[oaicite:1]{index=1}​.#### CompatibilityThe batteries are compatible with all DEWALT chargers that support 20V/60V, making them easy to integrate into my existing setup. I use the DCB107 charger, and it works perfectly with these batteries, ensuring quick and efficient charging​:citation[oaicite:0]{index=0}​.#### Final ThoughtsOverall, the DEWALT FLEXVOLT 20V/60V MAX 9.0-Ah Batteries (DCB609-2) are a fantastic addition to any DEWALT toolset. They offer outstanding power, flexibility, and reliability, ideal for both DIY enthusiasts and professional contractors. Whether you're cutting through thick lumber or powering up a heavy-duty leaf blower, these batteries will not disappoint. Highly recommended for those who demand the best from their cordless tools.

I originally bought these batteries because I had to. (60v Sawzall.)I also have several other 20v tools from DeWalt that are power hungry. These batteries sate them and run them at full power and potential for hours.9AH at 60v should translate to 27AH at 20v. There is a controversy as to how much you actually get but it is probably close. I have no idea as I have never been able to drain the battery, it always lasts longer than I do!I was doing some major destruction on an old structure heavily using my sawzall and three hours in I figured I should check my battery power. The indicator still gave me two green lights and my first thought was "When did I change the Battery? I have no recollection doing that!"The bigger batteries fit all the 20v tools I have but are cumbersome on some. They are very heavy and actually outweigh some of my smaller tools. Others, like my roof nailer, actually benefit from the extra balancing weight and power.I only have the standard 20v charger for these batteries and I find it absolutely adequate. I have a personal animosity to the 'Quick-Chargers' as I have used one before on a different brand of battery and it made the battery too hot to hold. I am pretty sure that is not a good thing.I have also seen the new 15AH 60v FlexVolt which is the same size as these batteries. Physics is a jealous mistress and I do not see how they can do it without a major compromise to life or reliability. You can buy two of these batteries for the price of one 15AH.

We are having no issues with the new batteries now

I have a leaf blower and only one battery which lasts about 20 minutes. I use the blower for leaves in the summer and snow in the winter. With these 2 new batteries I can now work for an hour straight and finish any jobs that I’ve started. Very pleased with this product!
