2 Pack 4.0Ah 20V LBXR20 Lithium Battery Replacement for Black and Decker 20Volt Max LBXR20 LB20 LBX20 LBXR2020 LBX4020 LB2X4020-OPE LBXR20-OPE Power Tools

I'm a big fan of the off-brand batteries like these, but these are the first double sized versions I've bought. They work great! They fit in all my B&D tools perfectly and they have the power to last. I can weed wack the entire yard with one battery and have power to spare. It would take 2-3 of the standard batteries. The only tool that I have an issue with these is the leaf blower. These batteries spin it so fast that I'm worried the fan blades will come apart. (I've had that happen before on regular batteries.) As much as I would love to use these in the blower, I'll stick with the regular batteries in that tool to play it safe.

The batteries work just as well as the name brand. One battery stopped powering my tools after one use, but the seller replaced it asap.

I needed a bigger battery for my edger and these batteries do an amazing job. They charge on my black and decker charger and they hold their charge. Powerful enough to get through tough grass with my edger.

Well, one of the batteries died today, so I got approximately two years out of it and now it won’t charge anymore. The other is still functioning, but I’m a little disappointed that this was the limit of its life expectancy.

I've not used it yet, but it did readily charge. Lithium batteries will become a thing of the past, so I was pleased to find one that will work on my gardening tools now. Hardware stores are not stocking them it seems.

okay so like two batteries for the price of one OEM? mine do alright, but still not as well as the original 7 year old that came with my B&D trimmer. They don't power as long and I've given some thought to this and my verdict is that these are about 60% effective. So I have three batteries in rotation and it works for me. [ I have a lot of trimming to do in my yard ] 08-31-2023 Follow up...............important to know: I purchased both batteries as mentioned and determined that they are nowhere near the quality of the original and they are not. in order to better facilitate usage I labelled these A and B. The B battery died and won't charge, time of death 08-29-23. the charger doesn't work too quickly and that is why I purchased extra batteries. Summation: The original battery is still doing great. These others are less than that, B puked after no more than 15 charging cycles. My original evaluation remains- inexpensive and worth it. I would buy again based on my experience- just keep your expectations low if you do.

Works like it was intended and charges nice

Price was right, has more than enough run time for me!
