Hi GnarledSage, the black and white wires are the ground and neutral wires. In electrical circuits, the neutral wire carries the current, and the ground wire is there just in case there is a short or fault in the circuit. Yes you can use just one of the wires. If I remember correctly, I believe its the white wire that you can use by itself. Instead of one of the wires hanging around and not connected to anything, I just connected both of the wires. Thank you for the question.
No you need more voltage to charge.. and amp will determine speed as long as the battery supports it. thats why car alternator charges at 14.8V to charge the 12v Battery
Nice video straight to the point, But I have a question, I have the charger for my cordless battery(which doesn’t work) can I hook up the laptop charger to the original charger? ie take motherboard out and just hook up positive and negative wires, then just slide battery on the original charging dock? Keep the oem charger just being powered up by the laptop charger?
Hello sabiya2, I appreciate it thank you. I'm glad that you enjoyed the video. To answer your question though, I'm not sure. What if your charger is the issue, the internals of your charger such as the circuit board inside. If you power the charger but the internals are broken, it still may not charge your battery. That is just my opinion. You do have an interesting idea though.
Hello sabiya2, just a quick update, I might have misunderstood your question, if you meant to remove the circuit board inside the charger and connect the laptop charger to the leads of the charger directly bypassing the circuit board inside the charger, then that might work. The downside is that you will probably be able to charge only one type of battery. You can only charge batteries that can fit in that charger. But still, what a great idea.
Hi thanks for your reply, ok so an update, what I did was I connected the laptop charger directly to the pins on the inside of the original cordless charger, so now I just slide the battery into the charger and it works with no issues. Thanks man
What if my laptop charger doesn't have red black and white? I have white, wrapped in bare wire wrapped in white again and then bare wire around that.
Why do you put black and white together? Will it work if that’s not done?

@@fixwhat1137Thanks for taking the time to explain.
@@GnarledSage You are very welcome
You are a genius
Please can you use an 18.5v laptop charger to charge a 20v battery.

Yes You Can.
@@-mejor-que-nostradamus-6152 thanks 😊
@@daytekone alright 👍
Can 19v laptop charger be used to charge 18v
Yes
