Ridgid 18v Battery Repair - Corrosion and dead 18650 cells 

Thanks for watching 😎

Distilled water is not conductive. The problem is all the minerals and stuff suspended in it conduct electricity. Distilled water has a negative ion charge, so if it comes into contact with loose minerals it will suck them right up and become conductive. If there's enough minerals dissolving into it, it will conduct electricity. But it usually doesn't if the board isn't flaking off or something. Still solvents are better.

Battery 1&3: 0 V across the cell pack can also indicate a bad board which has a short, and the cells will accept a forced charge to confirm this. 2nd battery: May not activate charging circuit. For all these, boards are available direct from Chy-nah for about $12

Not every component on the circuit board is a resistor

Can't open mine up but the broken one vibrates when tapped. Sounds like a tuning fork

I got a few batteries I've been wanting to troubleshoot. Where are you located? Maybe you can use them to make some new content.

I did this to mine and they now work but still won't charge. Do you know what the issue could be?

Qué voltajes debe de haber en los terminales de en medio?

Can you not just add the new cells in parallel ?? I am planning to just add the extra cells to the existing cells in parallel. Can't find a video, is it possible ?? I would be keeping the same BMS.

Nothing at the dollar store is worth a dollar. Please do nut buy things from the dollar store...especially things that go in or on your body...Being cheap can be very expensive.

I was hoping to replace the 18650s in them but damn it might be easier to buy a new set of batteries

I personally use electrical contact and spray them Most Ridgid batteries i seen have bad bms not worth fixing them

Your problem with the alcohol is that you bought it from a dollar store. True technical-grade alcohol is at least 99.9% water-free. I've NEVER had a problem with properly sourced tech-grade (or reagent-grade) alcohol.

What happened to the 9 amp hour Octane ?

You can clean a live board with WD-40, the WD means water displacement and the 40 simply enough meant how many tries till they got it right. I actually spray directly into many electronics especially switches and volume, gain, balance ext control knobs that have drop outdoors or squawking when it’s moved. Works amazingly good. Anyway, I doubt that intel would say this is a good method to even be on their boards and might even blame corrosion on them but corrosion stops when I use it on anything small and I am not counting lead battery to battery terminals cause that is simply a lot to ask of anything. It works on AC or DC current equally with AC that’s non capacitive as a capacitor on either can drop that voltage into you easily and it’s dangerous so be sure you properly and safely discharge them with any safe means you can use per that voltage output or a lead from + and - side in some salt water works on anything though can’t trust IMHO because no way to see it escape. Bulbs work well so long as voltage range is met. Lights and dims with draining of capacitor… WD-40 won’t short the capacitor but only said cause for a capacitor to kill you it requires no plug or battery connected at all being a power bank or storage place and unloads all power in fraction of a second making extremely dangerous! Anyway, WD-40 may be something you would like to try. Works serious wonders on electronics and for the record it is not a lubricant at all… thx and keep videos coming, getting better btw…

I have tons of Ridgid batteries but I registered them all for the warranty. I never had any issues yet that would cause me to use the warranty. But I suspect they'll try to make hoops to jump through. Incidentally, I just bought an adapter plate that brings the 18 V out for any use. I am sure Ridgid is happy about that. It is amazing to me how many components they have on the board.

Where did you get the scrapped batteries from? Cool video

Clean it with moonshine.

Do you know what’s causing the battery to shuts off when the battery is under a heavy load? My Ridgid battery shuts off in a fast start. Slow start is fine.

Is there a reason that you did not test each cell?

trashed and bought Makita products!

Why do you need to repair life time service battery offer from Ridgid??? Totally stupid. Just send dead battery to Ridgid to get new one done. Don't repair by yourself to void the warranty, Everyone should be not follow video to do repair it will void your life time warranty service/

How do you take out rigid screws they have a metal bit in the middle of the star bit
