External Battery Hi, just wondering if there were any external batteries about to get the acer w500 to last longer. Around 6hours is great, but like with my phone its nice to know it can last a bit longer if necessary. Whats the name of the power connector to the tablet? Thanks :) External Battery Hi, just wondering if there were any external batteries about to get the acer w500 to last longer.

In case anyone else stumbles on this...I use this baterry and have been very satisfied with it--it's a bit pricey and heavy, but fits nicely in a laptop bagEnergizer XP18000 Universal AC Adapter with External Battery for Laptops, Netbooks, and More

thanks for answering this, you may have just pushed me over the edge to buy this.

This is probably too late but take a look at the Symtek TF200. At about $30 it basically doubles the battery life of the W500 (I use it with my W500) plus it comes with adapters to use it in the EU/UK/USA, cigarette lighter adapter, and tips for just about everything made. This is without a doubt one of the greatest bargains I have ever purchased.

Tekkeon makes an external battery, MP3750. I use it for my netbook, tablet and telescope mount. It would probably run this tablet a good 6 hours by itself. Lots of juice. It also has a USB port that can charge phones and such. Check their web site for proper adapters.

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.

It took about 9 hours, which is not far from what they claim in the manual: 6-8 hours on USB.Charging an Acer A110 Tablet afterwards to a full charge took about 4 hours and emptied battery for about a half. Nevertheless, it was enough to charge Droid Incredible 4G to a full charge as well. Using solar charge is another story. It does not seem to like anything else that direct sunlight and by "direct" I mean literally pointed perpendicular to a sun rays. Also, manual says it needs 11 hours of sunlight to be fully charged, so I bet it would never happen. Otherwise, very handy device.

Is this battery listed as a match for you Compaq C500? Were the batteries defective? I just searched for a heavy duty (8800 ma, 12 cell battery) for my old laptop by using the model and make of my laptop. Found this one that you are asking about. Put Compaq C500 battery or heavy duty battery into the search box of Amazon and search. Also, CCheck to see what HP offers and write down the specs on their offering. compare them to what you pull up when you search Amazon. Try searching the internet for a heavy duty battery for your C500 laptop. Seek and yea shall find. Best of luck Chris

Hey man. Well I use my phone allot. Standard battery was at 15 % or less by the end of the day (unplugging the phone from charging cable at 5:30 am getting home from work at 9 pm) the new battery leaves me with 49% in the same time span. So I would say it gives me an extra 5 hours about. Depending on what you have running ( gps, wifi, 4G, blue tooth, auto rotation and the other sensors. ) if you use your phone allot in a day I would recommend buying one. It really does help. Charging time with Samsung 2 amp charger is about 15 min longer than standard battery. Hope this helps make your decision. Grtz Hey man. Well I use my phone allot.

I don't know what these guys are talking about it only lasting 8 or 12 hours between charges. What are they doing with it? I work on my computer 8 hours a day and have to recharge the battery every few months or so. What am I missing?

You can remove the battery in my Acer, so I'm assuming you can get a more powerful battery. If you have a Best Buy near you ask one of the tec's, or email Acer.

I have a small Acer notebook, it works as a charger or back up battery, once it saved me for 3 hours and still had 75% power remaining, I guess it depends how big your computer is, to prove it once, I charged mi iPod and phone 3 times each in it, then it was time to reload power.

I dont really know for your model but I can honestly tell you that for my acer 5742 the charge last between 2 and a half to 3 hours.

I really LOVE the laptop, I used to own the Asus F6Ve, and it's so powerful but with many heating problem, add on that the battery.The UL 30A-X5 is light, fast, amazing lookin, HOWEVER I seem to be attracted towards the battery statement of 12+? I'm fine with 10 hours though, which seems to be on the sticker on the screen when I first got it, but I want to confirm this issue with other owners/users.So, ElieenHow long does your battery last? it would be really nice if can share, please.thanks for the fast response

If you can take the battery out and run your laptop on just the power adapter - the battery is dead. My battery only lasted 5-6 months. Initially I got 3 hours on a charge - no more.

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.

I don't know how much help I will be, but I have had the tablet out of the cradle for 9 hours of on and off use and have not run it down to the point of notification. I do not think that battery life is much of a concern, since this is not really a tablet one would take on the road, or carry very far from the cradle, due to its size. But, just in case, I am confident it would last most of a day, perhaps less if you streamed movies the whole time.Keep one thing in mind; This is a heavy tablet and not much good for lugging around. I bought it mostly for the convenience of the one-button switch from WIN8 to Android.

I'm so sorry I didn't respond earlier. I don't know how to answer your question. The battery came without any instructions. But it works great for my little Acer (4-5 hours battery life).

I went to ebay and bought a half dozen of the highest Mili amp hour (mha) batteries I could find (bought the GOLD ones cheap) and a couple of plug-in-the-wall chargers cheap. They work great and you don't have to keep your computer plugged in for four hours or more to charge the batteries. The plug-in-the-wall chargers have a light that glows magenta while charging and turns blue when done. I use the radio quite a bit and this works for me. I always have a few charged batteries. Recording time on the highest setting with fully charged batteries usually runs around 7-8 hours There was probably a fit issue for any kind of AC adapter circuit in the radio.

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.

Hi! For my use (I don't do gaming, just regular internet stuff...videos, etc) I found it to have the expected amount of time - between 2 & 3 hours. I tested it out the second day I had it, although I use the ac adapter most of the time with my laptops. But I wanted to know what to expect, so I ran it on the battery just to test it out. I don't know if games and the like make a big difference on battery life or not, though. I hope that helps some. It seems like your basic battery life for a 15-17" laptop from my experience. I have 3 laptops. Two of them (this 16" and my other Toshiba, a 15.4") have 6 cell batteries and the battery time is about the same. I have a Dell 15.4" laptop with a 9 cell battery and get 4-6 hours with that.
