BLACK+DECKER 20V MAX* POWERCONNECT 4.0 Ah Battery, LB2X4020

The added power level for long run time is ideal!

Battery charge last a long time. Between edging and trimming my yard, it takes me about an hour. A single charge takes care of it all and I still have power when I am finished. Well worth it.

I recently bought the BLACK DECKER 4.0 AH Lithium Battery Pack (20V LB2X4020) from Walmart, and I'm really happy with it! This battery has made using my BLACK DECKER tools much better. The capacity gives great power and lasts a long time. I've used it for home repairs, and it keeps going longer than I expected. It's perfect for anyone who needs reliable power without constantly recharging. It's lightweight and fits well with all my BLACK DECKER 20V tools. The quick charging feature is also fantastic—it charges fast, so I can get back to my projects quickly. Overall, this battery pack is a great investment for anyone who wants to improve their BLACK DECKER tools. I highly recommend it, and thanks to Walmart for making the purchase so easy!

The 20V MAX has given new life to my Black+Decker yard tools. I choose OEM rather than some no-name because of prior original batteries and reports on third party batteries. Well worth the price and buying direct made sense and price was right.

I bought the 4.0ah instead of the 2.0ah to have a longer run time. The weed wacker worked hard for 40 minutes & the battery needed recharging. I sure wish it would've lasted longer before having to recharge it.

Mar 18, 2025 Order%23 2000129-15114370. Hello. I just received the 20v battery I ordered from you. It was adequately packed and boxed . with no obvious shipping damage. So I am certain any damage was NOT related to transit. The Battery was defective. Some of the four (4) female charging contacts were misaligned in the plastic body and one contact was bent/deformed - likely the result of poor manufacturing and/or assembly. How can you rectify this situation?

I bought 2 batteries, a 1.5 and a 4 ah. The larger one would not charge and gave me a flashing red light from the charger. The small one worked fine.

I received as a gift a Brand New set of Black & Decker Cordless Tools which included a drill, skill saw, reciprocating saw & flashlight along with a matching carrying bag. Everything looks great & I was excited to put them to use. I Went to charge the (2) 20v 1.5ah batteries and all that happened was a.Blinking Red Light for both Batteries. Needless to say everything is still Brand New sitting in the carrying bag. Would love to have used them.

I'd give it 0 stars out of 5 if I could. This battery was never even used and it wouldn't hold a charge. When putting it on the charger all it does is blink red. Very disappointed

I have the exact same experience as the other guy in the reviews. I have used this battery (along a B&D hedge trimmer) about a dozen times. I was happy with my purchase up until yesterday when I needed to charge the battery. It now indicates that my battery is dead. Really?? How can a battery only lasts a dozen of charges? I feel like I've been ripped off.
