What about output power (wattage) and battery life?

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

The battery life is wonderful. I have gotten well over 8 hours of play without recharge.

I can't give you any idea about battery life because I use this computer at my home desk, plugged in most of the time. But I can tell you I've been very happy with this purchase.

It would be 2 hours if the laptop was using 65W - chances are that the laptop battery lasts 4 hours because it's using less than 65W - a quick test would be to use the laptop while connected to the charger - if the battery charges up (from not at 100%), then the laptop would be using less than 65W, with the remainder of that going into the battery.

Not to be too vague, but without knowing the "load" that is on the system, there is no way to predict the amount of time that the battery will supply power. The battery will run a nightlight much longer than it will run an entire entertainment system, for example. I should think that the APC website may be of some help with this.

This info is taken directly from Lenovo's site:Battery energy (Watt-hours): 23.5WhBattery capacity (Amp-hour): 2.06 AhOutput voltage: 11.4 V dc (nominal)

Batteries last according to power consumption of usage. Anywhere from 1hr to 3 hrs depending on what your doing. Keep in mind that Core i7 processors draw more power when used at high percentage than most other processors.

Hi.I have owned this laptop for a couple of months now and it is amazing. The average battery life I am getting while running wifi and having the brightness about 3/4 bright, I am getting 5 1/2 hours. With wifi off running regular programs like Word, Excel and Powerpoint, I am getting about 6-6/12 hours. Amazing battery life

Ha...I guess the one down side...I get about two hours on max performance. I have been thinking about getting a better battery for the laptop (4 hour type or more). However, I need to add my purchase was more for a portable desktop than a mobile computer (tablet, etc...) so it stays plugged in about 85% of the time.

RE: FriedhoffJust a friendly reminder: HD level performance w/ GN40 means battery life will drop. Likely a lot. Link above shows current set up consumes 8W whereas GN40 setup consumes 14W... That *roughly* translates to only 40% drop in battery life, so 9 hours would become 5 hours!

Well, unfortunately I'm not an avid gamer so I am not on it that often, but I have found that if you have it in sleep mode it does a very good job of retaining power. If I were to estimate, if you played it as much as the average owner, I would say you could get a guaranteed couple days out of it...I might even venture and say three days. Again thats just a guess.You might wanna poke around online and google some sites that will give you some good insight on the battery life. Hope I was able to help at least a little. Have fun and keep gaming! ;)

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.

Need more information such as battery type, (wet cell, deep cell, etc.) brand, voltage, and amp hours rating before that question can be answered.

Your current usage will determine how long the battery will last.If your running it to full capacity,then it mightn't last too long.

On "Battery Saver" power settings with brightness of the screen turned down, for web browsing and word processing my battery runs to around 10% at about 6 hours or so. In the description on Amazon it advertises 6.5 hours of battery life. I'd say that is about correct.

The battery life is based on the number of times you cycle it, minimum of 500, but should get 1000. The build quality is above average for an offshore product, the weakest component will be the switch, treat it right and you will get the life out of it. See my review for more detailed comments and suggestions for improvement.

watts is just amps x volts so it depends on how many amps you are drawing from the battery

I hope this helps??? *Power: 10 Watts, 75 Lumens - 7.4 Volt / CE Approved*4400 mAh Rechargeable Lithium-ion Battery*Working Time: 3-4 Hours*Charging Time: 4-5 HoursDo not over charge it will reduce the battery life OK
