how long does this battery last on average
1828092
It lasts about two hours on lowest brightness. I have a white MacBook unibody from 2009 so the older model may be sapping the battery a bit.

I never let my battery die completely, but I would say it lasts on my laptop about 4 hours.

Put this battery in my wife's 2009 Macbook (the white one). This one is hard to answer, because you'd have to be using it continually to get a good read on battery life, and she doesn't use it that way. She can charge it, and with moderate, intermediate use, it won't need a charge for maybe 8 hours. We suspect if she were to use it continually, it would be more like 3, maximum. Generally, we expected much better performance from a new battery, but it is better than the nearly dead one it replaced. Oh, we also did follow the instructions for cycling it from full charge to fully drained several times. Put this battery in my wife's 2009 Macbook (the white one).

The battery is really nice. I have it over around 5-6 weeks but I charged only 2X. So super good, I use it every day. I am not watching Tv, so I have no idea, but I think you can use a small usb bluetooth adapter.

I really think the battery is ok, i have bought two of this laptop and if you are using it continuosly the battery life is approx 10hrs.

I'd guessitmate about 6 months. It's not an issue, in general, I don't feel like I am putting in a new battery often.

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

I am going to say probably 4-5 hours on average if they get a good charge during the day. I now need to replace the battery in one of them, but I have had them for about 4 months. The others I have are still going strong.

It does last longer than the original battery. I would put it at overall 3-4 hours longer.

I have the same laptop, and have been using the battery for about three weeks. So far, so good. The battery life is definitely lower than the original battery, but I didn't keep in-depth stats on the original, so it's hard to gauge. I get about 1.5 hours of life out of this battery when watching movies.

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

I got this on Aug 2013, and now it is only 6 monthes or so, and I use it not daily, but once--weekly, so the battery is still good, not 30mins, over 1 hr no problem. never measure it.

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.

On average it will last between 4-6 hours depending on what it is you're doing. I tend to leave it charging overnight so that it's fully charged in the morning. When I start doing my college course work and browsing the internet the battery will last me a good solid 3-4 hours while in constant use.

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

The batteries average life is 1 to 2 years. Usually after 6 months of use, it will start to give you less mileage per charge.

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 have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

I bought the mouse back in November and haven't changed the battery yet. I use it probably an average of 3-4 hours a day.
