What is the battery lifetime?

I have used the Acer on battery power for about three hours and it still had about 50% power left in the battery. I think it would go for about six hours or more if you turn off a couple of accessories like Bluetooth and WIFI and select the Balanced Power plan.

It depends on your performance settings and what you're doing on the laptop. I use mine with high performance and generally use light programs (MS Office) and web browsing and it generally lasts about 2-4 hours depending. The life of the battery can extend quite beyond that I believe by turning off features and downgrading performance, but I have not really explored those features fully.

The battery in my laptop came new and the life is about 8 hours. I hope this helps.

I have found the battery life to be almost precisely 3 years. Both myself and a neighbor of mine purchased this mower within 1-2 months of eachother and we both had to replace the battery within 1 month of the 3 year anniversary.

That I do not know 100 percent. But I've charged it only once a week and continually use it throughout the day with no issues. Awesome battery life.

You can't ask such a basic question like "how long does the battery last"... there are so many factors.How fast your CPU is set to run. LCD on time. HDD spindown time. WIFI being used...The best way is to CHECK the battery with "BATTERYINFOVIEW" from google.Once you get the "designed capacity" from the program, you can calculate the TRUE capacity in MAH which will give you a more accurate representation of how long the battery will last compared to a stock battery.

My $15 version is sealed also. Even with the display on continuously, the estimated battery life is 4 to 5 years. I plan to simply buy a new, improved version when that happens. There may be a more expensive version with a replaceable battery.

I would say the battery life depends on the display settings. With full illumination, I think it's about 6 hours.

I am not sure what the life span is. I bought the battery about three months ago and it drains in about 60 minutes. It has terrible battery life. I am not sure if I got a defective one, or this is just a terrible replacement part, but mine does not last very long at all.

I got it mid summer 2014 It had 10 hrs of battery. Since I'm an engineering student I never turn off my laptop and I'm always pushing it to its limits. It's lasted without any problems and still has 10 hrs(w/o internet of course). With internet it has about 8hrs. It's lasted 3/4 of the year with no decrease in performace

Good, I assume. I have been using it 8+ hours/ day for 5 dats a week and I've had it over a month now and haven't had to replace the battery yet.

I really haven't tested the battery life per say.....but I have had it on for more than two hours with the battery still holding charge. Hope this helps.

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.

The batteries have a life of 3 to 5 years. This is based on the batteries being kept in a good state of charge as well as being used in a appropriate temperature. The biggest factor that will determine the live of a battery is the temppetature. As the temp. rises the life goes down.

Honestly I have never measured the battery life but, for what its worth, quite a bit of times i leave it on accidentally for 2 days or so and it still has enough battery. If youre using it connected to the usb its not going to run out of battery because its getting powered by it.

The Ultimate remote contains a lithium-ion battery, essentially the same as you will find in today's smartphones and tablets. Li-ion battery life and lifetime are usually unaffected to any great degree when they are continuously connected to a charger, nor do they display a "memory effect" like NiCads. The lifetime of a lithium battery is usually a function of the number of "charge cycles" which may range from 300 to 1,000.
