Does the battery drain when the unit is not in use? If so, to what extent? (10% per week?) How long can I store it and still maintain its charge?

I have used it for the past couple of months and one time I didn't charge it for 10-15 days. The battery still shows 100% with no drain at all.

This battery unit will not drop any charge for weeks, not even 1% for the first few weeks. We have tested it for at least 3-4 weeks with minimal to zero drop in charge. Please keep in mind not to leave any cables attached to this device as that can slowly drain the battery even if no load is present.

The internal battery is constantly being recharged while the unit is operating. Has the unit been in storage for a long period? Also I believe there is a reset button on the unit. Just a small hole where you insert a pin or paper clip to push it. I don't have the unit in front of me but this would be typical. Good luck.

My unit came charged out of the box, worked for a week and didnt even run out before I charged it overnight anyways. Aside from initial charge, which i didnt pay attention to how long it took, I have charged it from dead at night to full 7 hrs later when I woke up so definitely doesnt take 24 hrs to charge

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable.Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.

The other person already said, but you cannot leave the battery in for any length of time or it drains. After each use, I pull out the battery for the next time. I just keep it all in a zip lock. Good luck. If you find the info, please let us know!

I've had mine for over a year. I just keep it on the charging base, use it, and put it back. I have never drained the battery, and I've noticed no drop in battery life with it being on the charging base 24/7.

I think the battery goes to a disconnected storage state rather than being maintained. More like you put it on a shelf after a full charge. It will slowly leak down

I had mine sitting idle for about 6 months and then checked it and it was around a 50% charge. It didn't go dead or anything. And charging it took a couple hours if i remember right. But that was several years ago.

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.

I mostly use mine for long trips overseas, not every day or kept in the car, so I had't really thought about. Just checked mine in the drawer where I left it fully charged when I got back from a trip in mid-July. It's still fully charged! Guess a pretty long time then! Hope that helps!

I use it for my cell and tablet and it stays charged for about 3 days to a week depending on use. As for keeping it plugged in, i would for safety just charge it and turn it off. If its not in use, it turns off to not burn the battery out. It is well worth the money. Mine has paid for itself more then once

Hey Derrick... I charged it when I received it on April 30. I use it on average 2-3 hours per evening. I use the back light function every 30 minutes or so and the unit is in standby during the 2-3 hours of use. I turn the unit off each evening. I have not yet had to charge the battery.

In my experience, it drained out pretty quick. It never did hold even for a full weekend. Mine quit taking a charge, period, after less than a dozen attempts at using it.

Hi! As you said, it tends to consume the battery. About 8-10 hours. Sincerely,

I've had mine for about 2 yrs. but don't use it daily, maybe weekly and it holds a charge like new. I think there are 4 major factors discharge (rate, depth), temperature (high), charge level and time. All affect lifespan, Deep discharges, high temps, over\under charge, high\low charge voltage are the things you want to avoid.
