ANTRobut 40 Volt MAX Battery Replacement for Black and Decker 40V Lithium Battery LBX1540 LBX2040 LBX2540 LBXR36 LBXR2036 3.5Ah

I've only tried the battery once. Black and Decker leaf blower/vacuum. Used about 30 minutes in vacuum mode, in the middle of power setting and the vacuum was still running strong with no noticeable slowing down. My original battery was only 1.5 AH and would slow down and stop at about 30 minutes. So I think this 3.0 AH battery will be an improvement. Time will tell as for how long it lasts. TIP: my original batteries worked well and re-charged well as long as I used them regularly . If they are left sitting on a shelf they will degrade and not hold a charge very long. Both of my original and very expensive batteries failed after sitting about 1 year without usage. Knowing this now, I'll use these new replacements more often.

Work perfect for my black decker trimmer really appreciate it Thanks 👍

Thank you for double boxing and wrapping in bubble wrap! Took a few minutes to get it on the charger but it is charged up and ready to go. Appreciated the quick delivery. Saved me money because I did not want to replace the trimmer. Will probably order another just to have on hand. Great vendor!

Worked ok first 2 years but one battery not so good the 3rd year

works so far, let’s hope it lasts longer than the other one.

This is the second replacement battery I’d bought from Amazon for my 9 year old B&D 36v string trimmer. The original wasn’t getting charged any more, and the first replacement battery would only charge to one LED segment. I sent it back and bought a different one. When the same thing happened with that battery I finally wondered if the problem was actually my charger. So, before returning the second battery I bought a new 40v fast charger, and lo and behold, the new battery charged fully. And so did the original battery… So for all those people railing about ‘cheap junk batteries’ and so on, “hold your fire”. The problem may not be what you think it is. To be fair, let’s point a couple of things out: 1. It’s hard to know whether it’s the battery or the charger without doing what I did. But we always hear about batteries failing, and rarely about chargers failing, so we assume it’s the battery. In this case, that was not true. How many of these reviews claiming bad batteries were unknowingly using bad chargers? 2. If you buy a replacement battery for a 36v device, all you can buy is a 40v battery. Even if your 36v charger works perfectly it probably won’t completely charge a 40v battery, so you won’t get the extended range you should from the higher voltage. And all those people selling batteries seem to conveniently forget to mention that. 3. I still can’t say how long either of my batteries will last. I’m a little leery of anything labeled a ‘fast charger’ for lithium ion batteries after hearing about all the fires. For safety I put the charger outside when I charged both the old and the new battery, and the old battery did get quite warm. But that could be because it’s rated at 36v and I’m now using a 40v charger (actually charge voltage is 42v) so it was pushed pretty hard. We’ll see if that eventually kills it. Anyway, I hope this helps.

I have tried for over a year to get this battery to recharge on the original B&D charger. After only one minute, the red light on the charger flashes indicating that the battery temp. is` too high and charging is suspended. Original B&D battery charges without problem.

Rated for more mAh than the original and performs as such. Order this battery in a 2 pack and now I can finally get all my weed eating done at one time with ease! I also like how the life indicator has one more light than the original for a more accurate indication of battery life.
