Comparison to CM2040

Is this a newer model to CM2040? What are the major differences? Does it use the same battery - 40V Lithium Max?
Asked by: Nancy
Look at the pictures of battery packs. This one shows a plain looking battery case. The more expensive CM 2045 shows a battery pack with an indicator that shows how much charge is left. As the other comment mentioned, only the more expensive CM2040 has the variable speed motor and 2 hr recharge. This one takes 8 hrs to charge. Slowly recharging batteries extends their life because it keeps them cooler, but be realistic, can you cut enough before having to wait 8 hrs to recharge?. All batteries discharge over time. Is it worth paying a few dollars more to be able to see the actual percentage of charge left versus thinking you charged it last time, but having it half dead so you can't finish cutting the lawn because it was partly drained.

20 in. 40-Volt MAX Lithium-Ion Cordless Walk Behind Push Lawn Mower - Two 2.0 Ah Batteries/Charger Included is rated 3.5 out of 5 by 33.
Rated 1 out of 5 by from Underpowered and problem-prone I have had this mower for approx. 2 years. If you have a thick, healthy lawn, you cannot take off more than a couple of millimeters without the mower bogging down when in the recycling mode. In warm weather, i.e. pretty much any time the grass is growing, the performance suffers further. Worst of all, it is unreliable. Ever since I have owned it the mower has inexplicably quit mid-job even though the battery shows 2 or 3 lights. This is especially true in hot weather. Installing a fully charged battery does not remedy the situation. None of the troubleshooting tips in the manual help. This product is a nice idea poorly executed. If this were a battery-powered car, B&D would market it like a Tesla, while in reality it performs like a kid’s toy that has no business being on the road. It’s poor execution makes me question the quality of other B&D products.

I went with this Black & Decker cordless lawnmower because I was tired of gas powered lawnmowers not starting and pulling and pulling on the starting cord. This Black & Decker mower is lightweight and easy to use. The only problem I had was one of the two batteries that came with it, would only charge 50 %. I contacted Black and Decker and they sent me a new one right away. Absolutely no hassle.

I find that I have to make sure the front wheels stay down because it is so much lighter than my old gas one! I haven’t pushed the batteries to the limit, yet, but one battery allows me to mow my lawn just fine...which takes me about 15 minutes since it is relatively small. But, the battery does show it is towards the bottom of the charge after that. Yes, the batteries have a charge indicator which is really nice. My pre-teen boys are able to use this no problem where I couldn’t leave them with by gas mower, yet, because it was difficult. And this cuts every bit as good...and so QUIETLY! Great buy that I’m very pleased with.

Rated 5 out of 5 by from I love to cut the grass now! Finally got rid of my gas/oil/spark plug/tune up/heavy/noise maker. If a lawn mower can be a joy this one is. At around 40 lbs. Easy to push and maneuver. Much easier turning and going around things. Starting is just push a button and pull the handle back, no more priming and pulling. Adjusting the height is so easy it's scary. My gas mower was a self propelled model that you just walked and it went. Well this one is about the same just walk and it goes with you, it's that light. If you have hills etc get a self propelled model. My lot is 60 x 160 so grass only is about a 14th of an acre takes about 45 min to mow so with 2 batteries I have no problem cutting the entire lawn. I mulch strictly. I never run the battery completely out. When I'm about half done I switch batteries and put on charger immediately if it's not too hot. This saves the batteries in the long run. And now I do not have to wear ear plugs. I can actually hear my phone if it rings. Only thing I recommend is getting the orange model as the batteries are faster charging and slightly stronger. A 4 rating on features because because of the charger.

I decided, against the advice of everyone with whom I discussed it, to try an electric mower. Putting it together initially was fairly simple and quick, and the appearance is superb (I really like the dominant black color scheme). I plugged in one battery, and let it charge. After about 15 minutes, the light started blinking, indicating an error. I plugged in the other, and let it charge overnight. When I came back the next day, it seemed to be fully charged, so I plugged it into the mower, and started cutting gas. It did not cut even 1/4 of my quarter acre lot. Even with two fully charged batteries, it would take two full charged on both batteries to come close to doing a complete job, and that just wasn't acceptable to me. It did a fine job on what it did cut, but it would just be impractical for me to use.

Rated 1 out of 5 by from I had an older version of the same mower, and cannot recommend it or other Black & Decker mowers ... I had an older version of the same mower, and cannot recommend it or other Black & Decker mowers to anyone as more than a large paperweight. It worked well for the first year I had it. After that, the battery's capacity dwindled over time. Three years after purchasing the lawnmower, the original battery couldn't hold any charge so I replaced it. That battery did the same thing as the first- worked well for a year, but its capacity dwindled enough that it's useless three years after its purchase. Through all of this, Black & Decker's customer support has been useless, and they don't seem to care that their products are of a horrible quality with warranties that aren't useful at all. Don't waste your money on this or any other Black & Decker mower.

Don't know why THRee separate features needed to start mower.( key inserted, push button,pull handle) eliminate button! Bagger tends to dislodge in uneven terrain. ONe larger battery instead of two small ones would be advantages. Button to open battery compartment on operating battery seems superfluous and cumbersome. Mulch feature is a plus. Light weight is advantages.
