JNC 660 repairing 2 jump packs boost packs 

I had to replace the battery in my Jump N Carry 660 recently and I noticed they don't give you much room to move things around inside the case. Its easier to pull the battery out, remove and reattach your connectors then set the battery back in. Also I had to go from the vertical threaded peg to the spade terminals with horizontal holes. Had to buy my own bolts and bend a bunch of connections to make everything fit properly. It was a hassle. But it also saved me 60 dollars instead of buying a whole new jump starter.

I've used mine for many years after using one at a used car lot. They sell all the replacement parts but my first ones batteries lasted five years of frequent use. Well worth my money.

New 22A batteries for these are $45. I have the same jump pack & just replaced my battery.

Been a much better video if you had removed the blurred out portion or told us why it is blurred. BTW My JNC 660 came from the factory with a B.B Battery.

Great job

Hey Coming back to your tutorial did you ever test check the batteries to see how much voltage was left or they totally dead. Some batteries won’t charge if below a certain voltage like 2-3 . But lithium batteries might be different. I guess looking at yours a dead lithium battery will charge up Thank you

Thanks for the video. I really appreciate the clear shots of the insides. Question: don't you have to make sure you're working in an anti-static environment when you're replacing electronics boards -- such as the charging board -- to avoid damaging them?

I have a weird issue I have to jump and carry 660 they were charging and all of a sudden they quit charging. No lights batteries check sounds good.. replace the charger system completely like in the video again for those out. What is the problem with this machine?

I wonder how good those batteries will be. I just had the battery on my JNC660 die after 10 years. Will not hold a charge. This seemed to happen suddenly. Would not jump start my car when it had only a week before. It charges up to the green fairly rapidly then loses that charge within minutes down to 25%. Clore told me today that I need a new battery. There battery is over $130 from any of the distributors....the cost of a new unit. I'm guessing that I have a BB Battery but Clores recommended unit is now a Proformer. Must be 22amp. I'm sure that not all batteries are equal and a $40 may not last that long. The BB Batteries are not so available on the internet as many other brands like AJC and Raion and others that claim to be Clore replacements.

I got one where both charge lights flash alternating. Any ideas?

I have the JNC 660 it keeps changing until I unplug it and plug in back in then it turns green.

Hello did you check battery voltage before ordering charger kit. If battery was near dead it wouldn’t be worth it when you could purchase new one.

Where do you get the replacement parts from

Nice video do you have links to the parts you used? Thanks

Why the blurry part?

Why waste so much time replacing everything instead of just trying the charger first?

Disagree with the conclusion. I recommend that you disregard this video. The original batteries are good, but do not last forever. The units pictured in this video will not function adequately in the field. The strong reading on the on-board voltmeter does not predict performance in the field. Think of a beautiful facade that appears at first glance to be a house. When you walk through the front door, you step into a vacant lot. There's no house. It's only the facade. That's the reading on the on-board voltmeter. No substance. If you tested the pictured units using a carbon pile tester, and compare their performance to new units, you would see that these units are weak, and most likely inadequate for any purpose. Note that the video does not include any form of field testing or performance testing. The amount paid at auction is waste. The amount paid for parts is waste. The time spent tinkering is waste. New unit, to your door, at least in US, cost is nearly as low as an adequate replacement battery. Lower-cost replacement batteries are bad, either DOA or short lifespan. You can restore original performance, but only with a proper battery, which is not a rational solution, given the cost of a new unit. I have formal university training in electrical engineering, I am an ASE certified automotive technician, I have run over 13,000 service calls, a little more than half were jump starts, installed more than 3,000 batteries, spanning ten years as owner of a roadside assistance and mobile automotive repair company. I have sliced this JNC660 problem every way imaginable, and the distillation is this: Buy a new JNC660. If Clore is still offering the coupon program for rebuild, save that coupon, and when your original unit fails, utilize that program. As an environmentalist, this makes me sad, but if you need this in the field for work, this video will only lead you to learning the hard way, what I have verified with my own experience. The author of the video is not an experienced field technician, and is not a trained and competent technician.
