2 Pack 3.0Ah Replacement Battery for Black and Decker 40V Max Cordless Power Tool LST540 LST136W LCS1240 Lithium Battery LBXR36 LBXR2036 LBX1540 LBX2040 LBX2540 40volt Lithium Batteries

No problem with using it.

I got these to replace the five year old original pack I have which no longer runs my chain saw (but does run my hedge clippers). These work well for half the price. Run the saw for plenty long for tree trimming, cutting up logs, and whatever else I need. Recommend!

They work well enough but not as good as the originals but then they are less than half the price. I can get by with them

Battery's charged up and work good. Seem to have a little less life over the B&D battery's but were a fraction of the price. Hope they last a few years.

I previously posted a poor review because I thought they weren't holding their charge in the second season. Then I realized that I was using the old B&D originals, not the Dutyone replacements! Very sorry if I led anyone astray.

Bought this two pack in September 2023. One of the batteries won't take a charge after only 10 months. Guess you get what you pay for. only had a 60 day warranty. Won't buy again.

Wanted to make sure batteries could stand up to contious use and charging before my review. After several weeks of use, I am getting about 30 minutes of mowing per battery, which is about enough for my yard. I run batteries until they are drained, then switch with a fresh battery and finish. I am confident these were well worth the money and would recommend them.

These batteries work very well with my Black and Decker weed eater/edger. They last a lot longer than the original 36 volt batteries. I have only used them once so far and one battery lasted until I had most of my yard edged and trimmed. They also work on my original charger.
