When using this unit can the battery be overcharged by leaving it on past the "battery full" reading?

We do it all the time. Charging over night. Doesn't seem to harm the battery. we are very satisfied with our unit. Hope this helps. If you are concerned, perhaps you should contact Inogen.

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

I saw nothing in the literature to indicate a problem with overcharging. I have not had the unit long so not much personal experience. So far it has been great.

I haven't experienced that. But if the battery is not fully charged it will not last long.

Its probably not a bad idea to avoid an overcharge however we do not have one on ours yet. We do not keep ours hooked up all the time for that reason and have not had a problem.

No, but it in ready the instructions about the battery - simply charging them over night provides a full charge with no worries of overcharging - it is very handy little deal

I've had my since February 2013 and haven't had to do anything to it. I don't think the battery is being overcharged- I think it turns that function off once it has full capacity. There is one side with half the plugs that is battery and surge protected and the other side with the other half of the plugs with surge protection. I am very happy with this item- it's plugged in under my desk and I've never had to touch it.

No, you should remove batteries when they are fully charged. The unit has built-in protection to prevent overcharging but why put it to the test continually? The risk of fire far exceeds the benefit of having a fully charged battery.

Yes. The charger is a smart charger. When the battery is fully charged, it goes into a hibernation mode and will maintain the battery, without overcharging it.

I know if you leave it plugged in all the time it can end up ruining the battery. But if that is not the case then I would contact the manufacturer.

I do not know if there is a mechanism to prevent over charging. For your second question: there is an LED with various patterns of blinking to indicate charge level. "Slow red blinking: 0-50%. Slow green blinking: 50-80%. Fast green blinking: 80-99%. Solid green: fully charged."

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine

Not really, unless you consider that to get it to light up, there is a minimal current draw while the unit is lighted up. When you unplug, there is no current draw. It really doesn't "Test" to get an accurate reading. It just shows what the battery reading is.

No, you can not over charge the battery. It does not have a charge controller but it has a voltage regulator that prevents overcharging (additionally, it keeps power from the alternator from reaching the panel). I have had mine plugged in for 7 months straight and can even drive with it connected with no problems.

Yes. Unfortunately, the unit I received doesn't retain its charge for much time.

Once the battery is fully charged, the controller will float the charge to the battery, this prevents overcharging. In other words, the controller ceases the charging once its full.

Does the digital reading show you a full charge? Is whatever you are plugging in drawing too many amps?

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.

I'd look in the manual for something saying "It will not overcharge if left plugged in". If you can't find such, then I'd plug it in and check the voltage on the battery every hour for 4-6 hours. If the voltage never goes above ~14.5V everything's fine, but if you see 15V or higher then you're "overcharging" and want to pull the plug.Another option to consider if you like the idea of keeping it "freshly charged" would be to put it on a timer that comes on for 15-30 minutes each day, but isn't on 24/7.
