How long does the battery last?
935345
If you mean when running on battery, the built-in display will give you estimated runtime based on connected active load. If you mean when will battery/ies need to be replaced, that can vary greatly anywhere between two years and much longer. Once a year for the first two years, unplug UPS and see if estimated runtime matches actual runtime - if close batteries are still good. After two years maybe start doing this test every 6 months or so.

1. UPS run-time on battery varies greatly by how much load is connected to it, but an estimated run-time is displayed on front panel. 2. How long before batteries have to be replaced also varies greatly, but will likely be two years or more. The way I keep track of the battery's usable lifespan is timing how long it takes for the remaining charge to drop to 75% when powering a single 100W incandescent light bulb when the batteries are new and then about every six months thereafter. When the elapsed time to 75% drops to about half of what it was when batteries were new, new batteries need to be installed. 1.

It really depends on how much power the things that you plug into the battery outlets need. Mine shows about 80 minutes with my home entertainment stuff plugged in.

That completely depends on the speed you are running it. If you only run it at full speed, it may last two hours on a charged battery. If you run at the lowest speed, it can last up to 15 hours or so.

I'm not totally certain about the battery life. I left mine on using it here and there through the day and it well into the evening before I had to plug it in again. I also know that I left in sleep mode for over a week and it still had about 70% battery left it. It impressed me how long it would hold its battery power

I have been amazed at how long the battery actually lasts. I use mine for Children's Church once a week on Sundays. I can go over a month before I have to charge it again.

The battery life has been great so far! I've had mine for two months, I never turn it off, and I use my computer for 8-12 hours every day. The batteries haven't needed changed yet.

If I remember right, I believe the battery lasts 4 hours. I personally love mine. I Keep it in my purse/backpack and it has come in handy more than I can tell you about here. I always have it close by, but I especially like that it's made in the USA (Florida).

I still average about 2-3 hours on mine. I've had in the neighborhood of 15 months. Been a great battery.

Hi,I have mine since two years ago, the battery had a duration between 2 and 3 hours, but since one year ago it last around 30-45 min.

the battery works quite well. it lasts at least one to two days if you consistently use it. although its off for a while, you still can turn it on without losing power not being used.

I haven't exactly timed how long the battery lasts, but depending on how much I use it, I generally need to charge it every day. Naturally I turn it off when I'm not using it, but I would say once a day with normal use.

Not long. about 15 mins. of run time. I bought a second battery so i could easily swap them out and keep going.

The battery doesn't last as long as the specs say it will, but then again, that is the case with all computers. I use quite a bit of CPU throughout the day, so without charging I would say it lasts 4 to 5 hours. Given the amount of CPU I'm using, I'm very please with that. If you are just using Microsoft Word and maybe 2 tabs of whatever browser, I would imagine the battery lasts much longer than 4-5 hours.

Usually the battery last between 4 to 6 hours. Just make sure you don't drain the battery. When you see that the battery is almost gone, charge it to prolong the battery life.

It actually has it's own built in battery. It lasts about 5-6 hours, which isn't too shabby.

The most I have had battery life is a little over 2 hrs. If you charge it and don't use it right away it will die. But honestly for the money its a good price. Hope this helps.

Not long. 20-30 minutes max. Mine came with an extra battery, which makes it use able. You always have to have a spare charged. Other than battery life, it works great.

Not long at all. Maybe 30 min from a completely dead battery. Lasts a good while too.
