I used this camping last year on my RV 4-5 times w/out issue. This year, the display shows -1 volt yet the blue charge light is still on. Ideas?

I'm having the same problem. (-1 displaying instead of battery voltage) Battery appears to be charging. Voltage at battery was mid to high thirteen volt range with panel hooked up, and mid to high 12 volt range with panel disconnected. Battery level is up after a day of charging. Battety load tested good at RV center during spring check up.

Yes the red light shows you're getting enough sun to charge, & the blue light shows its hooked up right & that it is charging. So if the digital display shows 1volt??? That means your battery is dead! Dead! Dead! & likely not accepting a charge. Anytime a battery goes below 11volts it's dead. + most batteries only have a 2yr warranty because they only last about 1.5yrs to 2yrs. Check & see how old the battery is,then take it to Orielly Auto & have them test it. Once you set that out of the way-i'd bet your problem is solved.

Check your battery ,sounds like battery not properly connected...or dead/damaged.

I need more information. What kind and size of battery was it attached to? Were you charging the battery with a solar panel, or what?

There should be two positive/negative contact markings on the battery. Make sure those line up with the contacts on the charger. The light should turn purple once an uncharged battery is put in correctly. When not charging a battery the light will be blue. Here's a picture: http://imgur.com/uYFAktx . It's upside down in that photo to accomodate my other plugs, but you can see how the battery is oriented.

Bad connection?? I haven't had this happen. Been using the gauges about 2 years now. If voltage is right around the cutoff of 4.5V I suppose it could blink on/off as the voltage hovers around that point. Gauge puts a tiny load on system so volts would drop, then without the load V would increase again over 4.5V so it would light up again, and the cycle would repeat.

It sounds defective. I ran mine over 2 nights camping, using a small rechargeable 12 volt battery. I only heard the alarm once towards the end of the second night when I dropped below 12v. I thought it was a great lite unit for the price. I used 12 strings of LED lights around my campsite and people were amazed at the effect.

My red indicator light never has gone off. I am not actually sure of this, but I simply leave the charger plugged in (AC mode) in the evening, then take it out of the charger next morning. I don't see any indication of overcharging or battery memory developing.

We use this TV in our camper and it is plugged into the 12 volt (Cig lighter like) connection. We have not had a problem all summer.

It might be a faulty unit. Like Jimbo, my unit charges easily--even an hour or so of sun is plenty for several hours of illumination. I'm very impressed with this device and hope that you have similar luck with a replacement lantern. Good luck.

On my unit the clicking is the overload breaker and the battery never charges. If I measure current it goes to 300mA then clicks, stop and starts again in a couple seconds.I found out that it is due to the winter! My charger worked fine in the summer, not this winter. I verified this by bringing the charger inside, warming it up and then it works! But only for some hours till it gets cold again. My recommendation... for this price, buy a different unit.

I would say that the item is defective and should be referred to the manufacture. I have not had any problem with the one I have on my RV. Hope this helps.

I bought it to maintain charge on a battery over the winter. The green light soon came on and I assume it is maintaining a charged condition. I won't really know until I put the battery in the car when the weather improves and see if it starts up okay. Quick charging was not a factor in my purchase decision. Maintaining a charged condition was the main consideration.

Had my charger plugged in for a few days with a battery from a recently purchased yard sale 18-volt drill. The unit was warm to the touch, but not hot. I have charged other batteries and they were warm when removed. The charger changes to a solid light when the battery is charged, and I usually remove it at that time. If it's getting really warm, I'd try a different battery if possible. If same result, then I would contact vendor or B&D; as a warranty issue.

I would make sure the batteries are both positive up in the charger unlike when installed in a remote in alternate directions like with most applications requiring batteries. You might also try another outlet to insure it is not the outlet causing the problem.

If I understand it correctly, it"s kind of like a "Miracle Charge" you would put on your motorcycle or antique car, but this one, "a microprocessor-controller that constantly monitors the RV battery status and automatically selects one of four charging modes: Boost Mode - (14.4) to quickly bring the battery to 90 percent of full charge, Normal Mode - (13.6) safely completes the charge, Storage Mode - (13.2), automatically activates after 30 hours of non-use or Desulfation Mode - (14.4), for 15 minutes every 21 hours to prevent battery stratification and sulfation (the leading cause of battery failure)." I think it monitors the batteries, locates the lo battery and re-routes power from another battery. It's not really a battery chargers, but more of a routing station. My RV has 5 batteries and sometime certain batteries use more power than others and this helps keep them all charged ith in the same range. That is what the hi-lighted section refers to. Mine has worked very well. Dont buy the cae they try to sell with it. Its plastic and will disappear with a good kick. I used a chain of a cable with a lock. I hope this helps, but I could be totalyy wrong.

The blue light around the barrel connector should be ON when the adapter is plugged into a wall outlet. If it isn't, I would try to plug it into a wall outlet in another room to make sure it isn't a wall outlet issue. If the blue light still doesn't turn on, it sounds like a defective unit and need it replaced. Keep in mind that you may still have a bad battery, but you will need a working AC adapter to determine whether the battery is still good. This AC adapter will charge the battery (when working of course). Hope this helps!

After a little more than a year of light use, mine blinks blue whenever plugged in and has no charge output (=DEAD). So, I think a flashing blue light means: get another charger - this one is DEAD. No surprise this item has been discontinued by the mfr.

I tested the voltage when batteries were very low and fully charged. My controller did what the specs said. Good luck

Mine was. The light didn't come on the charger or on my electric chair. My husband had a meter to test to see if there was any electric response and there wasn't. I bought the amazon 24V charger for around $50 and it's been working fine. I think I burned my charger out by leaving it plugged in even when I wasn't using it. Of course i've also had it for over 15 yrs.
