Can I safely leave this connected to a battery for 3 to 4 months ?

Yes you can leave it even longer without any fear of overcharging or damage to the battery

I have done that on a set of batteries with no problem, no boiling over and no damage. They also went from very very weak output to where the pair would start a diesel tractor at -5 degrees.

YES, IT WILL REACH 100% AND THEN MAINTAIN. It will not overcharge. . It will extend the life of the battery.

Yes. The charger will regulate itself as needed and doesn't over charge the battery. I've had mine for about a year now and have left it connected for months during the winter with no problems. I have several batteries that I switch it around on and can say it's helped all of them. One is about 5 years old and after using this charger on it the CCA's have increased and it's as long lasting and strong and it was when new.

acording to the instructions, it goes into a "maintenance" mode after the battery is fully charged, which can be left connected indefinately. I have not personally tested that feature. I have not been able to bring back a "failed" battery with this charger or it's close competitor, as tested on several batteries. It does seem to extend the life of a near failure battery, but only experienced on one so far.

According to the documentation the answer is yes, but I don't know that from first hand experience.

No it can be left plug up at all times in the wall or you can charge for 3 to 4 hrs and unplug

You can leave it in as long as needed. The light will change color when the battery is fully charged. However, once it is fully charged, it should be removed because overcharging can damage the battery and shorten its life.

Yes, you can leave it connected all of the time. It'll automatically stop charging when the battery is full. But why would you want to? The charger is always converting 110v AC house current to 12v DC battery charging current. That produces heat and wastes electricity (aka $$$). I unplug mine when the light goes green meaning the battery is charged.

Not sure what your trying to accomplish. I would assume that as long as it is not charged it last a long time. For more specific information I would contact the manufacturer.

No. You can leave it on for as long as you like. It would stay on stand-by mode.However the switch is easily accessible and I usually turn it off when I know that I am going to be away for some time.

It is a 2 part answer . If you use it regularly then it is fine to leave the batteries, but if it only gets occasional use or is stored, you must remove the batteries. This is not a rule for this lamp but all battery operated devices without regular use the batteries will corrode against the contacts and will destroy both your device and the batteries. All battery and device manufacturers warn of this.

My battery charge has reliably lasted 3 to 4 hours depending on what I'm doing on my computer.

No and no need to. It will be auto switch off when no activity detected for a while. Rechargeable batteries are built in and consume little power usually.

I am told you can but they hold charge for so long and charge so quickly it should not be required. I would not leave it on for an extended period. So far the battery has performed well.

I'd say NO. The owner's manual states that you shouldn't do this, as it shortens the battery's lifespan. How much it shortens it, it doesn't say.

You could leave the unit plugged in until you need it but it's not necessary. It holds a charge for a very long time. You won't be disappointed. I purchased this for my husband three years ago for Christmas. He still says this is his favorite present, EVER!

You can leave it on but it has about a 4 to 6 hour charge. If you have it connected to a power source it can stay on. It can disconnect if the item receiving the signal gets out of range. All in all this is a great inexpensive device. Write if you have more questions

I had one set of batteries last about 3 months.. the second one was still going at around 5 months when I took it off the wall.

It has been my experience that it is best to disconnect the battery once it is fully charged. I don't think it will be unsafe, just not good for the batteries.

The batteries are not protected and neither does the charger. So it is risky to leave it charging for extended period.

It can be left connected. The only time they recommend you disconnect if you are not going to use it for an extended amount of time so you don't shorten the life expectancy of it by it being exposed or just sitting unused in the elements.
