Replacement Battery for MSI GS66-005 Stealth

[CommanderAlex]

Hey guys, so I've had this MSI GS66 stealth for a little over 3 1/2 years and I've noticed for awhile that the battery doesn't hold it's charge that much between shutdowns and turning on and thought that the battery is simply worn out. I'd charge it to 80% Friday and shutdown before closing the lid, ensuring the power light goes off. Then, when Monday comes around, the battery could be 40-60% charge from 80%. I've noticed this discharge before since owning the laptop and thought it was related to one of the power states but I'm unsure which does what and if they can be adjusted in the BIOS. I've tried searching for possibly solutions but didn't come across anything that works.

 

According to HWinfo, the remaining capacity of the 99Wh battery is at 44.034Wh with a wear level of 41.5%. I've only charged the battery to 80% using MSI's software and never to 100% to preserve battery life. I did just recently do a calibration and that seems to have helped slightly with the discharge between shutdown-start over the weekends. 

 

I really just use this laptop for college and have no plans on replacing it anytime soon so is there anything I can check before deciding on replacing the battery? Also, is there any way I can get a genuine MSI replacement and not risk using a third-party battery?

 

Thanks!

I mean, the software is reporting data that fits your experience so while you could test the voltage across the terminals, that's gonna be less reliable than a loaded test which is what the software should essentially be doing. 

As for getting genuine replacements? You could contact MSI, but even if you can get one out of them, you'll likely get a nearly identical battery for double the price.

Yeah that was my hunch feeling that the software is reporting correctly in terms of what I'm getting out of the battery. 

 

I honestly thought I read somewhere in the manual or something that MSI has to offer replacement parts for at least 5 or 7 years according to EU law, however I'm in the US but I would think you can still get a replacement.

Can't hurt to hit them up. Just brace for the price they quote
