Very Imoprtant question about batteries

I am getting the sager 8690 and I am wondering if it compatible with any powerpad series and if not is there some type of adapter that lets it work with the sager. you get 1+ rep if you can fnd one.

Thank You

 

What does no one even know what powerpad is. Sheese

 

Would help if you offered a link...

Well, from looking at it it seems just like a huge extended battery to me.

It has 130Wh my Vaio's batter has 62,5Wh when fully charged and new.

You're possibly better off with a regular extended battery - or two additional normal batteries - also, the "value" would be determined by the laptop's power consumption.
If you have a gaming laptop you might just run it twice as long as a regular battery... on an ultraportable you don't want to lug that around.

Either get a spare battery if you need more battry life or carry your plug around - that's cheaper and lighter. (the power brick)

 

I am getting a SAGER NP8690 which is for heavy gaming but it doesn't have a lot battery life. I do some traveling and I would rather be safe than sorry. Are there any extended batteries you can recommend to me. Thank you

 

Try Sager - I've never had any of their laptops, but most companies offer them.

But you can pretty much forget "gaming on the go" - any battery will only be very useful to move from one socket to the next - let me guess, 30 or so minutes of battery life?

Your right I get about 45 mins when gaming. I dont want an all day gaming laptop. Just something that can last 2-3 hrs. I can't find an external battery compatible with any gaming laptop really. I was just hoping someone knew a battery compatible with the NP8690

 

Ask a mod to have this moved to the Sager Subforum - they know more about it.

 

okay. Thanks for the help

 

sooo does anyone know about powerpad or other external batteries in this forum?

 

External batteries, while useful, tend to wear out a lot faster than the batteries designed for your notebook. Part of the problem is the way most of them connect; since they connect via the power supply input jack, they "fool" the notebook into thinking it's running on AC power, which means the computer often stays in a higher power draining mode than otherwise. This means that even though the battery has, say, double the rated capacity of your notebook's internal battery, it'll often only last 50% longer. Depending on what kind of traveling you're doing, a DC inverter or some other form of travel adaptor may be a better choice.

 

I know but an hour and a half is longer than forty minutes. And besides My SAGER is undervolted so I am getting at minimum 2 hours but I need to find one that is compatible with the SAGER NP8690. I am so desperate I will give someone a rep.

 

That's the big tradeoff that Clevo has made this time, moneyman101. You can't have all the good things in one notebook. If you want to squeeze the most efficiency out of your battery life, then undervolt your CPU and GPU, and streamline your OS. You should be able to get to two hours. Or you can buy two more batteries for your notebook. The batteries for the W860CU are fairly slim so you can slip them into your bag without a problem.

 

ive read somewhere in this forum that the 8690 uses 3-cell batteries as sager never really meant this laptop to be used on battery power. that will get you an hours worth on regular task loading. unfortunately there are no batteries atm with a higher capacity that is compatible with a 8690.

as for the powerpad, i am familiar with the powermat. i saw it a couple of months back and was planning to get it myself. it wirelessly charges electronic devices, and has an additional usb plug for wired charging. it will only charge specific kinds of devices and if the powerpad is anything like it, it wont work with the 8690.
it looks extremely cool though. check it out:

From Clevo's webiste:

Removable Polymer Smart Lithium-Ion battery pack 42.18WH
Battery life 90 minutes (with nVIDIA GeForce GTX 280M, 42.18WH)

The M570TU has a 44WH battery.

 

Since I can't buy one I will make on. I found out about how to do this at

http://www.unplggd.com/unplggd/diy-project/how-to-make-your-own-9-cell-laptop-battery-058315

Insted of a 3 cell battery I will make about a 12-15 cell battery. It will be fat but it will be worth it. this just a quick diagram of my battery design. It will add about 1-2 pounds heavier. (I also have the original bottom of the laptop. It should improve my battery length to about 3-4 hours when gaming/ 6-8 hours when surfing web). Remember these are just estimates. Any questions or ideas please pm me.

 

I forgot to tell you guys that the reason I am not covering the entire laptop(even though it is obvious) is so the fans work and the batteries don't overheat. Also the reason I have batteries in the front and back is so it fits evenly on either your lap or desk. I am also thinking of making an external removable battery because the one I am making is not removable.

 

The bit you highlighted in black isn't the battery, this is:



Also, user manual page 39.

 

yea sorry. I just thought that looked pretty big for just a three cell and since I didn't get my laptop yet I wouldn't I will update it immediately.

 

It's because it's a lithium polymer battery, it doesn't use conventional cells so it can be any shape, so your idea might not be possible.

 

Here is an update(sorry it is messy)

 

I know but it is just a theory. One I get my sager I will mess around and who knows it might work. And if it can be any shape wouldn't that be easier to put on a laptop and make a cover over the batteries?

 

The problem here is how you are going to open the battery pack and connect your extended battery to the main one. Keep in mind that using different capacity cells, moreso different type of cells, is generally not good as battery readings will be inaccurate, and sufficient power draw at low capacity will be questionable. If the W860CU battery pack were conventional 18650 li-ion cylinders, then you can just use the same make and model cells for the battery. But because this is a new li-poly battery pack, finding matching cells will be impossible for you.

The W860CU's battery uses three cells in a three parallel circuit config. 3.7v x 3 = 11.1v. Each cell is rated for 3800mAh. You would need to string more cells to the existing circuits if you want to add capacity. But like I said above, I doubt that you will be able to find suitable li-poly cells. If anything, the only option you have is to construct a whole new battery pack using the existing DC connector and PCB regulator with li-ion cells. You can put as many as you want in the pack but making one that isn't bulky will be an issue.

 

Your right. I changed my design so it is more of a battery that gives the original battery the power. It will make more sense when I post a diagram tomorrow.

 

Have fun. 10char

 

I could also just make the battery and connect it to the ac in but that wouldn't be very effecient. As I said it is just a theory.

 

I think you're better off just buying a typical inverter. You would also need to pick up an AC to DC adapter to wall charge the inverter.

True but I don't wanna lug an inverter around so I unless I can find a small light inverter I don't think it is gunnea work.

 

(pedant mode on) Actually that is series, not parallel. Parallel would be 3.7v output. (pedant mode off)

 

Right again. My mistake.

 

But you had such nice drawings..
