Why doesn't Black-Decker make a lithium-ion version of this battery?

It would make the machine much lighter.
Asked by: BDuser
Just guess on my part but the Lithion batteries cost a lot more to make, they are more dangerous to ship, esp. From China, t

36-Volt Rechargeable Battery Pack is rated 4.7 out of 5 by 32.
Rated 5 out of 5 by from Nothing like a battery power lawn mower for a 70 yrs old Do not store this battery in sub zero weather. I killed the original battery.

Rated 4 out of 5 by from Necessary Purchase I have a lawn area greater than 7000 sq. ft. One battery will not suffice so I bought a second. That provides enough power for well over my lawn size (about 7300 sq.ft.) but allows the mowing to go forward without waiting for a recharge. I urge the company to tell a buyer of this cordless electric mulching mower to be prepared to buy a second battery with the mower if the lawn size is greater than 4000-5000 sq.ft. It will NOT cover 7000 sq.ft. I like the mower; it is a good one.

Rated 5 out of 5 by from Super fast delivery. I love my Black and Decker cordless, self-propelled mower. Because grass grows so quickly, and is very thick and wet during the spring, I wanted an extra battery just in case one battery became weak while mowing my large yard.

Rated 5 out of 5 by from Replacement 36-Volt Battery Gives New Life to Mower I love our 36-volt battery-powered Black & Decker lawnmower (SPCM19360), but the battery life plummeted at the beginning of its third season. It no longer could finish the job and before long couldn't finish half the job. We bought a replacement battery from Home Depot, and the new battery finishes the job on our 1/4 acre of grass with energy to spare. We will use the old battery as a backup during scalping season or fall leaf gathering.

Rated 5 out of 5 by from Glad I bought it but could have got along without it I bought this battery so I could rotate using one and having one on the charger. Also, just in case the battery runs low while I am mowing. As it turns out I only use about a third of a full charge (going by the built in charge indicator on the battery) every time I mow. I only have about 2500 sq. ft. of mostly St. Augustine with some Bermuda grass mixed in, so you're mileage may vary. I don't really need this battery, but I like the security/luxury of having it. I swap the battery that came with the mower and this one each time I use the mower, always having one on the charger. I like the charge indicator but I would like it more if it had a finer indication than thirds of a full charge. It beats no indicator as is the case of the battery supplied with the mower.

Rated 4 out of 5 by from Easy to charge and use Bought the battery pack as a back up for the self-propelled mower. I found that after two charges the battery on the mower is capable of doing my front and backyards without changing . I am going to keep it and rotate them, and who knows maybe this fall with leaf pick up I might need it

Rated 5 out of 5 by from Love the added meter! I purchased my electric lawn mower last summer, and sometime during our last move, our charging cord got lost. While I was pretty annoyed that I would have to buy an entirely new battery just for the cord (no one sells just a cord!), I am very happy about having a second battery, and I love that you can hit a button and see exactly how much charge you have left in the battery. Works great!

Rated 5 out of 5 by from The best battery powered mower on the market! This mower is built tough and durable. It folds up nicely and slides under my boat, taking no extra room in the garage. The large removable battery will last my entire yard including using the self propelled feature the entire time! I bought an extra battery to swap back and forth just in case the weather causes the grass to be very tall, but so far do not need it. I love this B &D mower. Its the best battery mower out there!
