black and decker 36v lithium battery won't charge

If this battery operates poorly or doesn't supply a sufficient amount of fuel to the engine, you won't even get your Black & Decker started. I usually just buy new batteries and authentic 18650s are expensive. Cheers. Hold the red clamp on the positive end and black on the negative end of the rechargeable battery for no longer than three seconds. Thank you! I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts. Thanks. Another just shows "bad battery… What's that guy doing in the laptop battery pack video? Let’s speak about the 16-volt lithium-ion Black & Decker vacuum. You could short the battery through a ring, but the worst you would get is a small hot spot. The price of lithium-ion batteries has dropped significantly as the demand has increased over the last few years due to the influx of small electronic devices. ~ karen! You can adjust your settings to allow this site to show ads. Me too, Mike! Just to let you know: If above is not working after all, you can buy replacement cells very cheap at the wellknown Chinese website’s which I will not mention but start with ali and end with baba and so on. And I also noticed Karen’s black fingernails, that were in the first few photos “natural” and then suddenly became blackened, only to go back to being au natural at the end of the instructions. ~ karen! like it kinda/sorta shows in 1 of the video's... Age of the BATT. Here's another example using a laptop battery pack. My charger was designed for cell phones. 2- Does this method only work on lithium ion batteries or will it work on other older types without blowing them up? The BLACK+DECKER LBXR20 20-volt MAX lithium-ion battery is always ready to go thanks to its ability to hold charges up to 500 days. There’s a hidden screw under a piece of plastic. I changed the battery in my Macbook Pro. Oh, and thank you Karen for such a wonderful video. JANRI Replacement LCS1620 LCS1620B Charger 20V MAX Lithium Battery Charger for Black and Decker 14.4V 18V Lithium Ion Battery LBXR20 LBXR20-OPE LB20 LBX20 LBX4020 LB2X4020 LBXR2020-OPE BL1514 LBXR16. ~ karen! ~ karen! I’ve done this without taking the battery apart. Micah, I agree that directly applying an uncontrolled charge voltage to a Li-ion cell can be disastrous, and that charging above 4.2 V per cell is definitely bad, probably dangerous, BUT, the whole idea, as shown here, does not involve continuous application of the charge, it does not bypass the thermal protection, it does not connect directly to the cells, and the wires are definitely not “designed” to connect continuously to the contacts…moreover, Karen specifically suggested short pulses, and continuous monitoring of the pack voltage, and only providing enough voltage level to “turn off” the UVLO circuitry…if one ignores every part of this process, and connects directly to the points shown, this is still at a point where the primary safety mechanisms of the pack are functional. You probably have an ad blocker running on your computer. Wow, I wonder how I can revitalize my batteries used in everything else (yes, I have a Ryobi cordless). So after the pulse fix. Your email address will not be published. Dedicated research after being INFURIATED with Ryobi batteries. Which means you hold your wires down for 15 seconds or so, then release them. All those electronics you’re bypassing are there for a very good reason. Then when I went back into Chrome it showed up. If Karen’s ‘hack’ works on a cordless, this will change my life! Step 1. And as we all know, half a screw is worthless. BUT it did load! What's New in iOS 14? ~ karen! Let us know in the comments below. A word on quality: typically more expensive batteries do use better quality batteries inside. ~ karen! You need half an hour spare time and a soldering tool and you have a new batterypack (with probably more capacity then before) for less than 10,-. Bravo! Put the plastic cover back on the battery pack (just the part that goes into the charger) and set your battery on the charger to see if it will take a charge. There's a hidden screw under a piece of plastic.  You need to pry the plastic off to get at the screw underneath. **Using the 40V MAX* lithium Ion 2.0Ah battery vs. the 40V MAX* lithium ion 1.5Ah battery Wooooooooooooo! I wanna see the vid :). Karen i hope you and Pablo have a lovely marriage and many beautiful children. Original review: March 18, 2020. Do you mean that these batteries are DC, and we are not to try to use an AC charger to pulse them? 36v lithium trimmer/edger. Is there a reason you have to take the battery cover off vs just pulsing the charger leads to the battery contacts the way the charger does? #2 Milwaukee ;) ~ karen! LED flashlights, Vape boxes, Makita chainsaw, Honda RoBo Lawnmower, every laptop I have ever owned, and all my USB chargers. To bring this full circle, the reason you are here in the first place, because your battery won’t charge, is a safety precaution built into the battery pack. Lithium-ion (Li-ion) batteries are rechargeable, but even rechargeable batteries have a limited number of cycles before they start to degrade. ~ karen! You do NOT have to buy a new $50 battery. Black wire = negative     Striped or solid white wire = positive. always always always remove any jewelry when working with electronics or electricity. I can only imagine the joy of living with a wife who knows this stuff……. This post is NOT sponsored by Ryobi. Repeat the "pulse" boosting and testing the battery until it will finally be recognized by the charger and you get the green light. The section under the V with the straight line(s). That’s right. The pulse charging with an old wall brick is good because chances are, the wall brick is current limited. Another of your brilliant ‘stuff’ I can steal. Click on an alphabet below to see the full list of models starting with that letter: ... 2 AMP CHARGE RATE AUTOMATIC BATTERY MAINTAINER. Unless you have incredible driving luck, you've probably had to jump-start a car once or twice, and the process for a lithium-ion battery is pretty similar (but not quite as dangerous). Lithium based batteries, even when almost flat, store a huge amount of energy, not electrical energy, but chemical potential energy. For instance, a $15 battery should not work as well as a $50 battery. O. M. G. This is such a game changer. It could be those batteries are genuinely at the end of their life. That battery never did charge even though I was able to charge it to 3 bars with a new battery, really expensive. The pulse fix kick starts the batter back into action. Step 5. Still the results were mildly successful since I used another packs already worn cells. Those are a standard in many electronics. It’s for a 10 year old cell phone, you’re never going to use it again anyway. If the battery you're trying to fix goes with a device you use on a daily basis, you'll want to do this over a weekend or find a backup you can use for a couple of days. A 18 v battery poses almost no danger at all. One for photos and one for the video. Full Recharge. Put the positive clip onto the large side panel and the other one into the clip on the other side and away it went. Step 9. Thanks Karen, it worked a treat, I really like your style. Re the video, when it didn’t work on Chrome, I got it to work on Firefox. You stick the battery in the charger and … nothing. I really don’t know how much experience you have at this technology, but this level of rhetoric is well beyond what is appropriate… maybe, something like:”not following the recommended procedure, or connecting voltages to points other than suggested, can result in damage to the battery pack, and danger of the battery pack catching fire”, Hi Karen – you’re fantastic – I read almost every one of your posts, and the great comments as well. Sorry about the whole marriage thing . Will have to drain a battery on purpose just to have the fun of trying this out!!! It’s not about current, even a 1 amp charger can blow up a battery. you have a BAD cell and this trick won’t work. 99 Join Prime to save $5.80 on this item Definitely have to thank you for this tip and add it to my Pinterest DIY. Chrome. Basically the battery can short out internally (NiCads grow metal fibers internally sometimes) and freezing/thawing the battery can make internals shrink & expand enough to break the short. Took about a minute. We may have some vintage stuff that could be revived. Hence the “mixed” nails. ~ karen! It's frankly kind of weird that you saved it to begin with. Remove the 2 plastic side pieces. If the battery is not fully charged, repeat steps 4 through 7. Thine the glory. Pull the top off of the battery case. WARNING: Dealing with wiring always poses a danger, so be cautious and make sure you fully understand the process before starting. My house fire started with batteries left in an old TV remote. To those of you who found this subject matter to be on par with spending 3 hours in a waiting room, sorry ’bout that. That’s interesting! Separate and strip off 1" of each wire.  You have *just* made booster cables!  Good for you. It takes around one hour to completely charge your Lithium-ion battery using this charger. That is why circuit boards automatically shut down when the voltage gets low. I have a professional charger that does exactly this procedure. Touching the red probe to the positive (red) terminal and the black probe to the negative (black) terminal, read the voltage shown on the multimeter. I love FRAGGING love this site! I have a Black and Decker 36V lithium battery leaf blower. You’re crazy and we love you. Der, you should propose to Karen, cause you could be an exlosive pack of energy together (poor pun intended). Release the clamps and check the charge level on the battery using the battery tester. – normal voltage at end of run-time 8.1 V -9 V Even if you leave the battery, the charge won’t deteriorate at all. I initially bought it because I needed a special tip for removing my Macbook Pro cover to replace the battery. You need to pry the plastic off to get at the screw underneath. It’s not the best thing since sliced bread – it is better than sliced bread. **********************************************************************************. I found you when I needed to change the motor brushes in my washing machine.
