BLACK+DECKER 40V MAX 2.0 Ah Lithium-Ion Battery, LBX2040

I like the Black%26Decker Batteries .I have used them a long time. This one is for my Blower so I can have an extra one to keep one charged up at all times. Service was great too. I received it in a few days.

Immediate availability and direct shipment to my address within two days.

Way better than the 20v battery you get, and it lasts a lot longer.

Holds charge pretty good compared to others

They are holding a charge well and actually last longer than the original two batteries that came with the lawn mower. Now we wait and see if they make it through the winter.

Just what I needed for my Black Decker tools.

This battery is not as long lasting as the battery that came with the weed eater - about 25% less. That being said, at least it worked once charged which is more than I can say about a 3rd party battery I tried. This battery costs quite a bit too. *Note: if your old battery still has some life, keep it around cuz you might need it. I did. Oh, if the old battery is still somewhat usable, keep the old charger as the new battery needs its own charger. This new charger will not not charge the older battery and the new battery cannot be charged using the older charging device. Rip-off if you ask me as both batteries fit into the weed eater just fine. I do like the weed eater though.

This battery is very pricey compared to similar other units. It seems to hold the charge longer than previous models but I have only had it for around a month now.

Batteries seem expensive and there are other options that are much cheaper. The new batteries drained just like older ones. The build quality and fit of the batteries are great.

Love the lawn trimmer with the edger bar, but the battery has issues. I've had this for about 18 months with maybe 8 months of actual almost weekly use. I can trim the perimeter of my house and my driveway, and a couple of trees, and then the battery is dead. While charging the batter, the charger starts flashing that it's overheating after a few minutes, even when I move them to inside my air-conditioned house. Today, I didn't even get to finish going around my house before the battery died. I have other batteries (from other companies) that have lasted four-five years while under similar use.
