Black and Decker lawn mower CMM 1000 How to change the battery in 8 minutes

[westvalley411]

What type of battery connection did you have? The manufacturer used a standard 8mm nut on top of the battery post. Sorry to hear that yours may have been different. I wonder if it was changed somehow during recall work? I suggest taking it back to the engine repair shop. They can check the battery viability. If you charge it overnight, it should hold a charge, not stall. If the cable is not secure you could have intermittent contact and the resulting stall. Please let me know the outcome!

Thank you for your excellent video. One thing you left out is that you need a special tool to disconnect the battery cables. I was all ready to change the battery and found I didn't have that tool, so I ended up taking my mower to a local small engine repair shop. After they changed the battery that I bought on the internet, my mower stalls all the time. I have only used the new battery this year. Do I need a new battery?

I luv this video! I have a question. I have an older model CMM 1200 (type 2). It's been throught the recall. When I remove the housing to replace the batterey, it has a weird stryo top, that is hard tyo remove because one wire it tightly underneath it. Even witht he handle loose. Any ideas?

@MisPinksunrise

Its possible a wire was shortened during the recall or someone on the assembly line was in a hurry and used a shorter wire. You could break the styro to get the battery out and then assess the best way to put it back in.Glue it with Elmers or any household glue just before or when you put it back in. My styro had a roughed-up side, probably swapped out or done the dealer 9 years ago @recall work.You can always use other styro as long as it stabilizes the battery Good luck!

Very well done video. I have had one of these mowers for a long time, I like it, my wife hates it, the batteries do not last long enough. My batteries have trouble lasting 2 years.

Sorry to hear about your unfortunate luck with the battery. I have no idea why there is so much variation in battery longevity. I believe the owners manual suggests keeping the battery plugged in when not in use. Makes me wonder if plugging it in 50 percent of the time and letting it fully drain would affect the battery life. My mower is in an outdoor shed and is out of the rain. Our humidity is generally "low." How about input from an electrical engineer out there!!

The B+D website states the batteries last about 5 years and should be plugged in, even after short periods of use. I'm lucky and dont know why mine lasted 11 years...hoping I get another 10 this time! Seems B+D should include written guidance on the plastic housing or handle to remind users about plugging it in...hey, satisfied owners buy more products! I use my 18v B+D blower several times a week and the batteries last only 12-16 months, but worth it not having a cord!!

Thanks Andy, I'm just about to go get my new battery. I have NO FEAR thanks to you!

You are welcome. Glad to know the segment was helpful. The main challenge was figuring out how to replace the battery without affecting the motherboard and other circuits, once you know how, its a breeze. Over the years several neighbors have purchased similar mowers and with millions sold, hopefully this will help other do-it-yourselfers.
