才知道，原來在磁鐵上接一條線，就能給電池充電，方法簡單又好用 #我愛電器維修

Connect two wires to the magnet It is very convenient to charge the battery Look, it's a scrapped horn Well, this black one is a magnet Uh, let me share this method with you. First look at this magnet because it is a circle It's not easy to connect when you tie this line. For easy operation Here I found two The small magnet that was removed behind the LED light It's easier to wire with it Next, find a scrapped mobile phone charging cable Cut it off from the small head And after that Then leave the red and black lines We put these two lines Attach it to this magnet respectively Because of this magnet It's easy to connect and it's more convenient. There are also screws on it. The black wire and the red wire are both connected respectively. Next, let's look at the magnet It's easy to see, you can suck it up Explanation, its magnetism is very good Then what we are here Find a phone charger and plug it in Use it to quickly give some This lithium battery activates it and recharges it Look at this lithium battery, it's been left for a long time can't charge Let's test it put it on the charger and see look The green light means it can't be charged. before charging it to activate repair First of all, let's measure its voltage Let's compare it after charging it Its voltage before charging is 2.86 volts Then what We can use it to charge it next What about charging? This black one is one of his abs connect it to the abs of the battery You see, just put it lightly and it will be sucked up. Then the red one is positive and negative gotta get it right Then suck it on the positive electrode in the same way. You see it is very convenient, right? No need for clips or tape It's very convenient to use Just suck it up Then let's take a look at this end plug it into the power supply In this way, you can see Activation fix for this battery About a minute after charging Then power off it Take a break for about half a minute. Charge it for another minute Wait a minute, let's measure its voltage again See how much power is charged in Well, I've charged it twice now. charge for one minute each time Then unplug it Then use the netlist to measure again See how much power it charges into Let's see if it can put this The battery activates the fix good It was 2.86 just now, now let's see 3.88 explain, that's it It can be activated and repaired for him. let's see We'll use the original charger when it's powered on you can charge it Let's see it turned into a red light, right? That means it can be charged. This method can be quickly repaired And it's to charge him in an emergency can use this method You see, it's very useful to use magnets. very convenient mainly ok video thanks for watching
