Predator Helios 300 Care Centre Battery charge limit issue

AndyAces

Hi there, everytime I boot up I enable the battery charge limit option but when I switch off the laptop and reload it is set to off again. Is there a fix to keep it on?

Product - Laptop Predator Helios 300 i7 3070.

Cheers,

Andy

Don't use battery charge limiter bloatware, the battery "longevity" concept limiting charging to 80% is a myth based on the old NiCad batteries that supposedly suffered from a "memory effect" debunked by scientists and is now even touted on the web to "work" for Li-Ion batteries. https://batteryguy.com/kb/knowledge-base/the-nickel-cadmium-memory-effect-fact-or-fiction/
ACC no longer has this battery limiting option or it has been disabled by Acer in the latest versions. It does absolutely nothing to slow down battery wear; a new battery can last 4-5 years whatever you do. Also trying to limit the charging is affecting BIOS and MS ACPI drivers in Windows11 possibly interfering with the new C0 Modern Standby protocol that may cause power problems. IMO you can uninstall ACC as you don't need the program, it uses resources running permanently on the background, the driver updater causes issues with Windows11 WAU and ACC hangs a lot. You should do a complete charge cycle with a new battery for BIOS and Windows to register the battery capacity and never let any battery deplete to zero charge (impossible if Windows Power Plan is set correctly with factory defaults) as cells will die and the battery won't be able to charge anymore. You can leave the adapter or USB-C charger plugged in 24/7 without causing any detrimental effects on your battery wear.

Thanks for the concise answer, it seems odd how large companies like Acer, Samsung etc fall for this unscientific option and have devoted time and resources to make a setting for it but at least I don't have to worry about battery damage if it has nil effects. I think I will uninstall as it does seem to slow down the laptop.

Hi,

After I uninstalled Acer Care Center (ACC) I never had Reliability Monitor error events occur again! I think this feature would be valid if it were implemented directly in the UEFI firmware / BIOS (as other manufacturers have done), and not the way it was done through faulty and untrusted software.
