My Noco Boost is Dead...can I fix it?

My Noco Boost GBX55 booster pack will no longer accept a charge. I believe the battery voltage has dropped below the level where the internal electronics will start charging. No lights on the pack...she's dead!
This video is my attempt to resurrect the jump pack where it can be charged via the USBC port and continue to get me out of trouble when I run down the car battery!
*Disclaimer - this can be dangerous. Do not take my advice. Do not attempt this unless you're completely comfortable with electronic repairs.... and you're desperate!

this may sound goofy but if the lithium ion packs below detectable voltage you can try this as I have had some success with other battery powered items that develop the same issue. Just plug and unplug the usb charger over and over again for about 5 mins, this seems to give the battery a small charge each time it is plugged in and it usually will start charging and numerous bump charges as I call it. Nothing ventured nothing gained.

Thanks for the vid. Been repairing Ryobi batteries in a similar manner for a while now and was looking to see if similar process could be followed for these ! I’ll open mine up later today ! Thanks again

Cool! Hope it works out for you!

What charger was used to charge the internal battery I have a gbx75 that’s got the same issue
Thanks

[@makeadventurecanada]

I used an RC car battery charger. But any small charger would work. I think the biggest thing is you want to charge with very low amps…just enough to get it above the low voltage cutoff. So go slow and low so you don’t do any damage. **I’m not an expert so do what you’re comfortable with!

Use the 12v car charger connection for about 20mins then plug try it with usb. The car charger is strong enough to overcome the resistance of the battery.

@@phil111ify i can confirm this works. saved me buying a new jump pack. Thanks

Does it perform the emergency bypass for jumping dead batteries ?

[@makeadventurecanada]

Yes, works as normal.

Same as my genius 10 peace of crap
I never even used .New out of the box

​@@HondaFit4AdventureI think, the GND potential of the USB is wired directly to the battery Minus. So, Minus to the USB GND and Plus to the Plus terminal might work.

Great video

Thanks!!

[@AmericanConstellation]

Well this sucks! i just bought one. Maybe I should send it back! Why should I have to fix it after 6 months? What a piece of crap!

[@garrettvella8831]

For what it's worth, I had the gbx 45 and when I needed it it was always working for 3 years. But, I drained the battery completely and left it in a drawer for about a year and that's what killed it for me. As long as you check it semi frequently and keep it mostly topped up it should last a while longer than that.

Mine is 3 yo as well and I used it lots, great little unit…..But i let it go flat and now I can’t charge it. No happy

[@garrettvella8831]

@@liamgross7217 I've since managed to revive mine by applying 12v directly to the battery just untill the voltage reads above a certain threshold and then plugged into a usb charger, it seemed to work pretty well if you're comfortable with disassembling it a bit. Don't have to mess with any solder luckily enough.

[@liamgross7217]

@@garrettvella8831 much appreciated. I’m going to try it on a 60w charger tomorrow, apparently people have had some some success doing that. If not I’ll pull it apart, I can’t hurt what’s not working I guess. It’s been really good up until now.
