I would imaging that there is one online somewhere but really just hook it up as you would jumper cables. Charge it for 1 day every 3 months or so and it will stay charged.There's also a test button on it to see how much charge it has. I've used mine a lot since getting it and have had no problems. I keep it in my truck always
this one is not to be charged more than an hour after use .. do not leave it in to be charged it will burn out .... the first charge is to be 24 hours after that only 1 hour after use (if needed) or charge about 1 hour per month .... the next model up with the blue case you can leave charging as it has an automatic cut off when charged this model does not ... I have had the jnc 4000 for 3 years and it works perfectly ..
First, It is the best. Got me, friends and strangers out of being stranded. Never failed, just make sure it is charged.
Throw it anywhere in the trunk and it is ready to be used. No particular position needed to be stored at.
Yes, Clore offers replacements (see Cloreautomotive.com) as well as other battery dealers can match one (like Batteryspec.com). Replacing it will cost ~1/2 the price of a new pack, so if you don't mind the time to unscrew things it will save you some.
