I would love to know if were able to set a charge limit so it extened the battery life in the feature something like 60% or 70% charge ?
is there maybe a software can do that ? ( though I doubt it )

Only a few laptops manufacturers still offer this software to limit battery charge, like Sony(now Vaio), Lenovo and Samsung. There is no third party software for this, because it would need Bios or EC control. This is old tech, modern lithium batteries don't require it, so it is out fashion.

thats not true even Tesla car only charge the cells to 4.1v to extend the battery life . honestly i am more worried about heat since the case of this laptop gets hot

With other laptops, the solution is simple, just use the machine, and when the battery wear gets high, get a replacement. No luck for us. Heat can be concern, especially with battery swelling, that seems to be happening relatively frequently now a days.

This store is the only one I found that carries replacements for EVGA, but I am not sure about the quality of the battery, since many years ago someone at NBR got one for his Razer Blade and the battery was faulty, he even asked for a replacement and it came with the same issue. Hopefully they got better. http://www.storebattery.s...=EVGA&x=9&y=16

As far as the usefullness of software limiting the charge to 80%, I only have my own experience with my Vaio Z, that inhereted the sofware from Sony. After a year of using my Vaio Z limiting the charge to 80%, I had 9% wear, while my RB charging to 100% and a lot more heat when gaming, after a year I have 2% wear. What I figured, to decrease wear, I always try to not let it drain below 40%, max 20% on my EVGA because the battery life is pathetic. The consensus is that the greatest stress on the battery is draining below 40% and charging over 80%, since the charging part is not possible to limit, I stick with not draining the battery to low levels.

No way i am paying that much I can pretty much find cells that fit inside the laptop and harvest the protection circuit from the old pack

Yeah...I will probably do the same, when the time comes.

Just because our battery meters say "100%" doesn't mean that the cells are charged the the maximum chemically possible lifespan-killing amount. Presumably EVGA has set "100%" to be a charge level that is a good balance of utility and lifespan.

Nope , unfortunately i checked the battery voltage with aida64 its 4.35v each cell :( (fully charged)

Where do you see the cell voltage? I installed the trial version but only see the total voltage. If the cells hit 4.35V, that is not awesome. https://electronics.stackexchange.com/questions/317717/how-much-can-i-overcharge-a-4-35v-lipo"...overcharging of 150 mV over the nominal 4.2 V leads to about 10% more capacity for first 50-100 cycles, but the service life shrinks from 500-1000 cycles to about 200. " However, the data cited in that link is now 10 years old--hopefully it isn't as bad any more.

will divide the total cell voltage by 4 since the battery pack is 4 cells in series (it might also be 2 in parallel) this is why i made the post though keep in mind this cell are 3.8 not 3.7 so the full charge voltage is 4.3

In a couple of years, hopefully Halo Tech will post a guide on how to build a battery using the original charging circuit, right? I wish they managed to fit a 99Wh one on this machine, the battery life is so pathetic, that when it does fail, I can live with just using it plugged in until Halo Tech shows how to build a new one.

You bet I will :D it actually very possible to increase the capacity since there is some space near the battery I just wish if evga enable nvidia optimus in mine :(

True....no battery life and no g sync doesn't make sense.

Halo, I know that on some machines with G sync, where the iGPU is disabled, such as the GT73, it is possible to enable the iGPU in the Bios (hidden menus), and boot from the iGPU. Both can't be enabled at the same time, of course, but if this works on the SC17 it might be interesting to run on the iGPU on a daily basis and reboot when the dGPU is needed. I will give it go and let you know if I have any success....or not. At least the CMOS reset is easy on this machine if I get a black screen...  an extra 30-60min would be awesome when websurfing, streaming, office work, etc.

I don't have much hope though, since I think on the GT73, the iGPU is wired to the screen, although disabled, because it has an MXM GPU port, so when the slot is empty, this option makes it possible to boot the laptop......let's see.

Good news is the iGPU is enabled.....now I just need to figure out to load from the iGPU on boot.

Sorry for the false alarm. It is not possible. I can enable the iGPU as a device, as shown above, but it cannot direct output to the device like on the MSI, that has the option to output to VGA.
