It has a reverse polarity prevention relay. If the battery being jumped is completely dead, it won't trip the relay to pass the current from the internal battery. It is a bad design

Sorry, I've never tried to replace the battery, so I wouldn't know? I really don't use mine anymore and I'm looking to get rid of it. It's just collecting dust in my garage.

I have never been successful using this unit to jump-start a completely dead battery. I needed it 3 times and ended up calling AAA each time. There is a circuit that looks for proper polarity before it allows current to flow. You can plug a device in the front port and you probably have 12 volts there. I don't see any point in replacing the battery as the polarity circuit makes this product useless. Worst automotive purchase I ever made.

Hmm, maybe try holding the power button until the green light goes away and then start it up again.

It looks to be an internal battery. You will receive a cord that plugs into the unit and into a 110 outlet to charge the unit. I can't see a way to open it up and replace the internal battery.

I re-charge until the green light goes off. This is only when I know I'm going to need it soon. Obviously if it will be weeks or months before needing it, I don't re-charge.

The battery isn't replaceable. If the charging cradle isn't functioning you can plug the charging cable directly into the remote. If the battery has expired you are out of luck.

I'm new as well but have not experienced this. Mine has recharges within 2-3 hours and light turns green. It may be the unit?

You are not seating it in the charge properly and the unit has to be turned off when put in the charge. It will start off red and turn green when charged.

Unfortunately, I think your unit, like mine is DOA. This unit charged all lights and then I took it off the charge and it did nothing. DEAD!

I'd start with the battery. If the unit has not been used in a while, the battery probably has lost it's ability to be charged.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

It appears that the battery replacement is glued together by the factory. It seems that it was never intended to be serviced. The low cost of this unit would not make it cost effective to repair it. I'm a professional technician.

Try reversing the way the battery fits in the charger. Turn it updside down and put it in and it will charge. Topside will only display a green light and will not charge it. Hope this is clear enough!

I m very satisfied with my replacement.I make sure it cut off and turned down, so that it will charge properly, so the green light will turn red. God bless you.

Buying a battery might be a cheap fix. Make sure the charging unit is plugged in and it lights up when the unit is placed in the charger. If the unit is new, send it back.

I think you may have gotten a defect battery because I only charged mine for an hour or 2 when I first got it. (I disconnected it because the charged light turned green) and I was able to use it all day yesterday and today. I still haven't gotten the low batter indicator.

Dead battery? Get a jump! haha Seriously now.Are you sure its the battery? Does it work when its plugged in? As soon as you unplug,does it stop working? If that's the case,I'd take it in to a computer shop to get looked at.Is it still under warranty,& if that's the case,send it in.I haven't looked at my own manual,but can you change the battery yourself? I'd see if I could do it first myself,instead of paying omeone for something you might be able to do yourself.

All you need to do, is charge until you get green light. I purchased a second battery so I can rotate them out. Had mine for two years and no problems. We live in FL so use them a lot...
