I know this is an old thread but to the ones replacing batteries just because they're low in voltage don't forget that most chargers won't recognize the pack if some of the batteries are below a certain level. To remedy that you can take a charged battery and jump a wire from positive to positive and negative to negative for about 15-20 seconds just to get enough charge in the pack for the factory charger to take over. Or buy the Amazon charger, remove the batteries, charge, ect
@@SlangNasty Yes, you can do that. However, that really only works if the entire battery pack is low. If only 1 or 2 cells are low voltage, then jumping it to get the overall voltage registering on the charger may only bring it back to half bars, but better than totally unusable
Just a suggestion. Shorter time with the iron on the cell. You want to be quick with the heat. Flux will make it solder up much more easily and cleanly.
You also can't test the cells when they are connected in parallel with one another. You will get the combined voltage of all the cells in parrale. It can give you an idea of which group of parralel cells contains one or more bad cells but the only way to know for sure which cell amongst them is bad is to disconnect and test each cell individually from that group of parallel cells.
@@4_Nik_8 good call, and that's what I thought too. As you can see on the video, I actually get a reading from each cell individually, and can tell which ones are the bad ones. They have me the same reading hooked up in the battery and on the bench by themselves. Try it out
No offense intended. But is there a way to get the average schmo. A working battery. After I buy the Amazon charger the multi meter, soldering flux and all the things. I'd save money just buying a new battery.
Mine is not blinking, charging or any lights on or off the charger? I tried jumping it from one battery to the other and nothing. It will flass all green while jumping but nothing when you pull the wires off.
Just take it apart like the video shows and check each cell. Some of them will likely be close to zero so you will have to change a couple to get the battery back to good
Sorry, don't know how to help, but I have extra batteries to get spare parts from. I've heard of people going to the home improvement stores and getting them out of the battery recycle bin to have some extras
@@hacktical521 but if u look at the bottom of the battery where it hooks into the charger, there's like a square aluminum piece inside the notch on the positive side. I have 2 batteries missing it and they don't work, it's gotta be that I believe
@@WilliamCintron44 I actually just fixed a battery tonight that had that same problem. You can follow the video, take the battery apart, and check each cell with a multimeter to see which cell is low voltage. Then you just replace that cell and it will be good as new!
Thanks for getting back to me your video was very helpful, as I took one apart today and 4 of the 6 are bad after charging overtime. I found them pretty cheap,under 5 bucs each so it's worth replacing, ty
I'm sure you could find the 18650 cells online, but I have extra batteries to get spare parts from. I've heard of people going to the home improvement stores and getting them out of the battery recycle bin to have some extras
Yeah, that probably means that one or two of the cells are bad but the other ones are fully charged (or at least in the right voltage range to not need charging). I'd recommend following the video and taking the case off and checking the cells individually

Vape store has these batteries
Thank you, much appreciated 👍🏼
Would it be cheaper to order batteries off line an repair batteries
I believe it would be, yeah. Just get your own set of 18650 cells or whatever your battery takes and then replace them as needed

Unless you already have most needed
@@gamingunlimited5804 If you have the stuff good. But if you have to buy the stuff just get a new battery and walk away.

The cells are good in mine. There's a piece that fell out of the positive control panel. Idk what it's called, u know anything about it?

Im having trouble with my battery what type of cables should I use
Can you explain what your problem is in more detail?

@@hacktical521 it's the process easy to change
where do you buy new batteries to solder in
You can find them online at lots of retailers. Just make sure you were getting the right kind, like the 18650s or 21700s

Why do kobalt batteries have three contacts or prongs or connectors?
I believe the extra lead is for giving data about the battery, like temperature
What are those black strips for?
Just to stop possible electrical contact with outside sources. I just use electrical tape to replace them if the originals are too deformed
my battery will show full charged but only lasts a couple of minutes in my 80v push mower
Strange. You could take it apart and see if it has dead cells
Where can I get replacement cells
I'm sure you could find the 18650 cells online, but I have extra batteries to get spare parts from. I've heard of people going to the home improvement stores and getting them out of the battery recycle bin to have some extras
@@hacktical521 thank you sir

I have those 24volt kobalt that all 4 leds flash when button pressed, put it on charger and it says it's charged but dont work???
