Powilling 2Pack 40V MAX 2.5Ah Lithium Replacement Battery for Black and Decker 40V Battery LBX2040 LBXR36 LBXR2036 LST540 LCS1240 LBX1540 LST136W Black+Decker Lithium Battery

Well pleased with batteries. I have a Black and Decker battery operated chainsaw, weed-wacker, hedge trimmer, and blower. As you can see, when I am working in the yard and using all of the Black and Decker products in the same day, I need extra batteries. Well pleased with the Black and Decker products I own.

My old batteries were 3 years old and ran out of power before I did. My new batteries run long enough that I'm worn out before they are. Can do all of my yard (1.2 acres on a corner lot with a curb) shortly after changing to the 2nd battery. Well worth the money.

10 months after purchasing:One of these is still working and the other is totally dead. Won't charge, won't power anything. Says it has "half charge" (two lights), but it's totally dead.Product listing says "12 Month Warranty", but I see NO way to actually get ahold of the manufacturer and the Amazon "Return and product support eligibility" button says my "window" for product support has already closed.If someone from the manufacturer is listening, please contact me so I can resolve this.

I was thinking these might be knock-offs but they are not and hold a charge reasonably well. I cleared maybe a 1/5 of acreage with one charge. Very impressed with the quality and charge time.

These batteries seem too good to be true; their charge lasts twice as long as the original Black & Decker battery...

Bought two of these for my weed whacker. They work as good as the original for half the price. The original still works, but I need more than one to do the whole yard. Very satisfied.

Purchaser battery regretfully only lasted 3 short months. Bad return policy!! Battery won't charge! Waste of money, don't buy! Here's your warning. Run

Bought two one failed to recharge after first use for twenty minutes. Not sure how to file warranty claim?
