When fully charged how long will it last without using ? So say i fully charge it and throw it in the trunk say two years later after never touching will it still have enough charge to jump start a car?

The instruction booklet suggests charging every three months if left dormant. We just put in our phone's calendars to make sure we have a full charge when needed.

I generally charge mine once a month. It only looses a small amount of charge in the month, generally less than 5%. I keep mine in the trunk of my car just in case. Great tool!!

As long as you keep the battery charger hooked up to your battery between uses, you should have no problems. I left it on my battery without using my car for over six months and it started like new. Good product.

Your car has to be able to charge the battery that way so i'd check your owners manual just to be safe if you havent already. but we had a Toyota Prius and the ignition battery died so bought this and a quick jump kit. we jumped it from the cig lighter anytime the car wouldn't start. we never left it plugged in longer than to start the car.hope this helps!

2 things: The battery is small from a capacity standpoint. Upgrade the battery. Second, the car sits low so if you run it through grass it will drain the battery quicker. We run our in the driveway and street mostly and it will last about 20-30mins with the upgraded battery. Also suggest getting a spare and a fast charger.

I bought the car in January- the battery was fully charged and I still haven't charged it at all! My kids don't drive it everyday but it does get used about 3 times per week for about 20 minutes at a time. I read that over charging the battery tends to cause problems so I've been waiting for it to run out before I recharge it. I'm totally shocked at how long it's lasted.

I've been using this charger for about 6 months. I put it on when I'm not going to be using the car for a while. When the light is green, the battery is fully charged. You can leave it on the car, and it will keep a trickle charge going to keep the battery charged if your not planning to drive the car often. I'm using this on a 2005 645Ci. My mechanic said that I should make at least a 20 mile trip per week to keep the battery charged through the alternator. I figure that if I'm driving less than that I should leave the charger on the car.

This unit is not a "constant charging" design. That is what makes it a cut above the rest. It charges to full charge, and then only senses that battery's charge level. When charging is needed to bring the battery back up to full charge, it turns on again. I have had one on a stored car's battery for almost a year as I have never gotten the engine back together. Another sports car I have may sit for a week or more without it being started. It has a Battery Tender attached to its battery too when that car sits.

That is a really good question and I'm not sure I can give you an answer for it. I have used my device strictly to jump start my car death battery so I don't really test it real well.Sorry that I can't be of real help, hopefully you'll find someone who can give you a real answer!!!

You won't get much benefit plugging it in while jumping, as the onboard charger only charges at a low rate compared to the hundreds of amps the battery puts out during a jump start. I wouldn't bother trying to do that- just use it and then put it back on charge.

My son isn't always great about fully charging as it takes about 8 hours. With a four hour charge it lasted about 20 minutes of heavy use. I would guess significantly longer life for full charge. He's used it in snow and it seems good. Not sure on the tire size, you can get that from the website. Not sure what the LX5 is. Overall, it's been a good car thus far.

No, that is a misprint or something of the sort, it is not at all suited to jump start a dead battery. However, if you were to leave it hooked up to a (nearly but not entirely) dead battery for 10 minutes, that would usually be enough to get the car started unless the battery itself is not just drained but also worn out or damaged/defective/etc, or unless it is very cold outside.

To be honest, it hasn't got much use in my household over the past year. We seem to just use the car charger and stick with one battery. However, I did use it the other day when I wanted to bring a backup battery, and it worked fine. For the price, it's a lot more durable than I expected. I hope that helps!

It charges a weak battery. If the battery is, for example 50% charged and it only takes several minutes to bring it back to 100%, some cells of the battery are dead rendering it useless. Won't jump start a car, not it's purpose. There are chargers/ jump starters, but be prepared to spend more $. It will, however,serve as a maintainer should you plan to leave the car sitting several days. It's all in the instructions. Be safe, read the instructions. On rare occasions batteries get hot (to the touch) meaning they are going to explode. I always touch the battery after a half hour or so.

According to Clore's website (http://cloreinfo.com/matching-your-jump-starter-to-your-vehicle/), they suggest charging it every 3 months when not in use.

I've never had it take more than 3 hours from completely empty, but it depends on what you're charging it with. As for how long it holds the charge, mine has held a charge for a couple weeks and any loss in capacity was not apparent to me. It may hold it longer than that, but I have used it so frequently that it has never been left alone longer than that. Make sure you charge it fully before first use, the longer the better for that. I believe the other answer was either a defective product or not fully charged the first time, because of how fast they lose the charge and how short their charging time is.
