20-Volt MAX Lithium-Ion Cordless Combo Kit (2-Tool) with FLEXVOLT 20-Volt/60-Volt MAX Lithium-Ion 6.0Ah Battery Pack

it's nice to have long lasting battery for saws and impact tools plus i the isn't much heavier than 3 ah or 4 ah

This large, heavy battery fits a variety of Dewalt tools from 20-60 volts. Have tried it on my 20 volt drills as well as on my 60 volt saw and it works perfectly on all. Fast charge in about an hour. Keeps going a long time, exceeding the 20 volt batteries that came with the drills. Take one type of battery to the job site for use in all your Dewalt Flex tools. No more keeping up with extra batteries for each and every tool. This is a one size fits all that actually works as intended. Charger cooling fan is rather noisy.

I need an extra battery for my Dewalt 60V Cordless Circular Saw to have a backup when the original battery that came with the saw. One great feature is that being FLEXVOLT Battery pack it changes voltage when you change tools. To a 20 Volt Max tools. This FLEXVOLT battery powers the new line of 60-Volt Max Brushless tools and 120-Volt Max Brushless tools. This pack is also backwards compatible with 20-Volt Max tools and chargers. PLEASE NOTE that this requires a charger that can handle the 60V batteries. The 20V battery cannot handle the charging. Great battery.

At first I expected these new lithium-ion battery packs to be much more lightweight compared to the older 18V battery packs. These new packs are just as heavy, but they are more powerful and longer lasting, so that's the tradeoff. It's nice not having to worry about creating unwanted memory though, so charge away, preferably when the battery is depleted though, since there are a limited number of charges for each battery (the number of times you can charge should easily last for the life of the battery though, so don't worry if the battery isn't completely dead if that doesn't work best for you). The batteries have a push button that turns on LEDs (total of three) which indicate the power level left in each battery. A lot of the tools will now warn you when the battery level is getting too low, which is a nice improvement from the batteries/systems that we had to use before. Before, you had to wait for the tool to stop working. This battery is NOT bluetooth enabled, and I probably wouldn't consider it since using bluetooth will just kill the battery while you're trying to impress your co-workers. I really like the red protective shipping cap. It locks in place, which is perfect for when the batteries are not in use. The older 18V batteries had tiny red plastic caps that would easily be lost if used in any work environment. These new packs will hold up and appear to be very rugged. It's a good idea to have at least one spare battery so you can always keep one charging while you are using the other. If any tools require two batteries, then have two spares available with a dual charger to keep you going.

This 60 volt battery has me very excited to expand my cordless tool collection and will finally let cordless tools, especially saws, keep up with their corded counterparts. Anyone who has used DeWalt's cordless circular or reciprocating saws knows they pack a decent punch but they don't have much of a runtime. This battery tackles that in two different ways. There are extremely powerful 60 volt versions of these tools available but unfortunately I haven't had the funds to add any of those to my collection yet. However, this battery also works with newer 20 volt tools as well, and so far I've seen runtimes of 3-4 times as long from my circular and reciprocating saws compared to the 20v battery. These new batteries are bigger and heavier than the 20v battery but they're really similar in size to the older 18v batteries. For the additional runtime it's well worth the added bulk. They also charge from the standard 20v charger, so you don't need to spend extra money upgrading to a new one. I'd highly recommend picking up this battery whether you're looking to add more powerful tools or just make your 20v saws last long enough on a charge to be useful in larger projects.

This is a great battery sytem. It's powerful and lasts a long time before having to be re-charged. I love not having to drag a cord around with my battery operated circular saw. The downside is that the battery+charger is expensive. The good news is that once you buy the battery and charger the other Dewalt Flex volt tools are compatible and are value priced. If you use or need a circular saw, reciprocating saw or table saw, etc. this is a great system to go with because of the powerful battery system. I hope you find this helpful.

No complaints the best

We really like the battery. Much more power.

Nice last long only time will tell how long...

Other than the price being to high, I feel this product is also essential to my needs to run power tools.
