How many hours of use are in each fully charged battery

It depends of the quantity of oxigen every person requires, my husband use the Respironics in 4, it can last about 4 hours when they are new, and after some time, only 3 hours. I always take another two for replacement!

The battery takes 2 hours to charge on the initial charge, less later if some charge is left. A full charge lasts 25 hours. From the moment the light starts flashing, the battery is in a low-charge state and has 4 hours left. Great battery life!

It takes 8 hours for both batteries to be fully charged from empty to full. But most of the time you probably find some capacity remains in the battery, so it will take mostly less than 8 hours. Charge it every night before you sleep, and it should be fully charged when you get up. With full charge, it can run about 20KM which is about 12.5miles. (testing on flat surface running non-stop).

The first charge should be 14 hours to give your battery full capacity charge. Then, one 3 hour charge will last for about 36 hours, or you could charge it every night like smartphones.

I might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

I just used mine for 6 straight hours, and 2 hours the day before, still going strong. I would estimate 10 hours full charge to dead.

Hi, Dakota. Each battery assembly half is rated at 9 amp hours so the unit is a total of 18 amp hours. I think the warranty is two years. I have had mine in service for over a year and a half and it still charges up to full original capacity.

I charge mine over night and then use till it starts to slow down then over night again. I have forgotten about them in the charger for about three days, they were hot, and over the years it seems to shorten the life of the battery. so 8 or 10 hours for full charge.

About 4 hours per use. My last battery lasted about 3 years before I had to replace it.

I haven't done a test (like running movies for hours to clock the battery life), but I would say about 6-7 hours of use. I use it a lot, but only need to charge the battery every 2 days or so. No battery gets used when it's off, either (I know that sounds silly) - for example, I had charged it fully and the. Had it in my bag for 3 days before taking it out to use it, an the battery was still charged to 100%. So far, great battery life. Hope that helps.

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.

About an hour with regular batteries, 2+ hours with Energizer Lithium Max. The rechargeable batteries don't last long at all because they only start out at about 1.2 volts.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

I should add to my previous response that the battery life on a full charge is at least 8 hours.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.
