Operation time for extended batteries(12-cell, 8800mah): 4+ hours, however, the actual operation time will depend on how much electricity is required by the device and how you use it.

About 3 hours with "heavy" usage. My son who has Dushene MD uses his laptop while up in his electric wheel chair. Controls everything around him and throughout the home with it; thus "heavy" use.

Depending on usage, this battery can last up to a few days w/out charge. Good bang for you buck!

Cannot truly say, I was using it 5 - 8 hours daily and it still had battery. If I had to be over night without a charger turn it off and start the next day, it still ran but limited.

I don't use it every day and I have had it almost a year and I think I have charged it about four times so I would say the battery is pretty good.I have shot it for over an hour at a time and it still had a lot of charge left.

I've had mine a while. I usually keep it in my purse for emergencies. The longest I think I've kept it without using it was about 2 weeks and it was still charged, so I'm sure it can last longer (I just haven't had to test it for more than that).

Sorry, but I have no idea. I can tell you this the battery doesn't need charged often.

I haven't had too much experience with the battery as I usually have it plugged in. But it seems to last around 6 hours depending on what you do

What is the shelf life of this battery unit if I plan to keep it as a back up battery?

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.

I can't say over the long-term, but I have had mine for three months, I use it everyday for hours at a time, and I have not yet had to replace the battery.

A couple of hours with regular use. I ended up getting a second battery and that's been great, but not necessary if you charge it regularly.

It hard to say but I leave mine on charge the day prior to using for a period of time. I can get about 7hrs playtime.

Not sure but mine runs for 3 days plus off a leisure battery without needing re-charge.

i have had the battery last about 2 days without a charge. it will also depend on the type and volume level of the music bring played. i listen to bass heavy music fairly loud and 2-2.5 days is what i get.

Hello Linda. I bought this battery just last year when the original died of natural causes. At most, this sucker last me about an hour to an hour and a half after it's been fully charged. Might not seem like much mind you, but I tend to use the internet a lot and stream things online, and different pages up at once. The less you use, the longer it'll last bit I was reall happy when I got it. And instalation is pretty simple. Let me know if this does/doesn't solve your riddle. I will try again for you. Please have a good evening.

would think it would stay charged for 5 days if turned off when not in use. But to be sure, take an extra battery.

A fully charged battery will last a long time. Several days of continuos use.

I use this at work, every day, for 8 or more hours a day without recharging. I have no idea how long it exactly lasts but it has never been a problem so far.
