| Jun 10 at 11:53 | comment | added | JW0914 | @JasonVorpahl To build on DanielB's comment, laptop batteries only have ~100 - 200 charge/discharge cycles before their charge capacity drops significantly, with every charge/discharge cycle lowering the charge capacity by several mAh, and after ~200 cycles, it often sits at ~50% of the original charge capacity. The power management software on a laptop works is by cutting the power to the charge circuit while still using the charger to power the laptop (the charger's primary job is to power the laptop like any other PSU, with a secondary job of charging the battery). | |

| Jan 27, 2022 at 21:25 | comment | added | Jason Vorpahl | Thanks so much John. As I said it was a fun experiment but the more I thought about it the more I knew that it may be more complicated to really have this work like the vendor supplied software. I only had it running for a day so no major harm. | |

Your setup needs to keep the battery at a relatively stable charge rate as I noted. Simply having a setup that turns off charging and turns it back on frequently will not help. | |
| Jan 27, 2022 at 17:12 | comment | added | Jason Vorpahl | Daniel B, this is exactly what my concern was. I'm a software programmer and don't know enough about how the actual battery management software works and how to not make things worse. My concern was if I do this I am discharging and recharging a lot during the day and that may hurt the battery. It was a lot of fun getting this to work but the more I think about it the more I am wondering if there isn't more too the battery management software than my simple setup. | |

| Jan 26, 2022 at 20:28 | comment | added | DrMoishe Pippik | Nice idea! Unfortunately, many PC's do not come with power management hardware, but your work-around should solve that problem. Please publish the script and circuit. 80%, give or take, might be optimum charge point, and having on-off closer together would decrease depth of battery cycling (e.g., 79% and 81%) You can also try downloading HP Power Manager software. support.hp.com/us-en/document/c06179452 , but if the PC does not have hardware, it won't work. | |
