Replace for 9Ah Dewalt 20V 60V Max Battery DCB609 DCB606 DCB612, Compatible with Dewalt 20V 60V Cordless Power Tools and Battery Charger DCB118

I use a DeWalt leaf blower with Flex Volt 20v/60v batteries. I am not a contractor, so can't afford to spend the BIG $$$$ on name brand batteries. Took a chance on this off-brand battery in the 9 Amp Hour size (same size as the one that came with the blower.) Very happy with it. Fast delivery. Charges up quickly with my DeWalt DCB115 charger. Seems to last nearly as long as the original battery. Has a state of battery meter on the end that works.Battery is just slightly smaller and lighter than the DeWalt battery.Can't speak to longevity because I just got it and started using it.For the Money - a great option. I can buy 4 of these to one of the name brand.

Will not charge on my DCB112 charger like it says it's compatible with. Charger recognizes it but thinks it's full charged and it only has 1 light on. My Waitley and Dewalt batteries charge on it no problem. I now have a $45 paper weight. Only tried this brand because of Torque Test Channel's good experience with them. I'm obviously not so lucky.

Does the job. Works great in my dewalt chainsaw as a backup battery.

I've had 2 of these for around 3 months now and can say a few things:* the price is nice compared to the "real" Dewalt batteries.* these do run my mower (which is why I bought 2) reasonably well* these are quite light in comparison to the Dewalt batteries (pro or con? lighter is nice! but may that means there isn't as much "stuff" in the battery pack)But, the lifetime is clearly less than advertised. I have 2 of the 9Ah Dewalt batteries (from a leaf blower and a line trimmer) that last a fair amount longer than these.Anyway, I wanted to put a concrete number on it, so I just ran discharge tests on both of the batteries I purchased. Here's the results!First, I discharged at 12A, which is a high, but in line with what my mower would use (I'm estimating). In theory a 9Ah battery will empty in about 45 minutes.Also, I used a Rigol DL3021A DC Electronic load to test these batteries.The first battery discharged from 20.8V down to 15V (which I consider empty) in 28.5 minutes. That yields a capacity around 5.7Ah.NOTE: I did a constant discharge on this test and wasn't present when the voltage got down to 15V. The test continued to discharge the battery all the way to zero volts! This really shouldn't happen as most Lithium Ion battery packs should have a battery protection circuit that will disconnect as the voltage gets low, to prevent overdischarge. I'm not sure what's really going on here, as they must have some IC on the batteries to show the battery level via the LEDs when you press the button on the battery--that's usually a protection IC as well. Anyway, after that, this battery would not charge on the Dewalt chargers. Luckily, I used a bench power supply set to 20V with a current limit of 1A to sort of "jump-start" the battery back to life and it did come back. I do know that Lithium Ions can become useless if overdischarged, so I'm glad it still appears to function normally (time will tell). Anyway, this might be an important point as some (many?) of the tools may not have a protection circuit and can potentially overdischarge the battery. I did see other reviews that mentioned not being able to charge the battery anymore--perhaps this is what happened?On Battery #2 I used the Rigol DL3021A battery test (vs the contant current test above). This stopped the test once the battery got down to 15V. This battery came in at 5.8Ah, pretty similar to the first battery. I'm adding a virtual panel capture from the Rigol after I removed the battery..Upshot? I'd label these at 6Ah batteries. Sure if you discharge more slowly, you'll probably get more coulombs out of them, but I'd like to think the labelling matches the use case (e.g. a mower of a leaf blower).I'm also reasonably happy--for the price I think a 6Ah battery isn't too bad, but cannot give 5 stars for something that isn't as advertised.

I bought this to replace a dead DeWalt DCB609 battery. Those new are insanely priced so I was motivated to try something else. This battery is plug-and-play. That is, you can use it in your DeWalt FlexVolt devices and it will work immediately. I have used it on my DeWalt DCST970X1 string trimmer and DeWalt leaf blower with no issues. The leaf trimmer was easier to use since this battery is a little smaller and lighter so not as hard to handle. I have no way to compare battery life of this to the dead battery but even if it doesn't last as long it is considerably cheaper a well worth a try.

It's a little early to tell about longevity but for a third of the price, it's excellent replacement. It's great to have options!After a year of use this by no means holds up to the original Dewalt battery, I would estimate that it lasts only about 50% as compared to the Dewalt. You get what you pay for.

Bought in Spring - did not last till Fall. It has been used with Leaf Blower to clean a driveway maybe once a month. Simply stopped charging. I decided to replace it with original DeWalt although it costs 4x as much.

Great replacement for 20v <=> 60v Dewalt Batteries
