Dell power manager5/2/2023 ![]() ![]() ![]() So, the answer to your question is, "There is no answer". I have yet another battery that had degraded to 92% of its design charge four years ago when I also started using that computer on AC power most of the time. I have another battery that had degraded to 88% of its design charge four years ago when I also started using that computer on AC power most of the time. I have a two year old Dell battery that still reports that it is charging to its maximum design charge. Like you, I normally have my laptops connected to the electricity supply. I have looked into the subject many times but have not found any authoritive guidance for Li-ion batteries Whilst there was a consensus about this decades ago for older battery technologies, there is now no general agreement at all. If you gathered together ten experts you would get at least eleven irreconcilable opinions. Should I use the Custom setting in the app to limit charging to 80%? I want to maximize battery life in my new Inspiron 3493 All of the Dell apps I use on that laptop are for win7 and installed in Windows 10 using Compatibility mode.ĭell Power Manager: Is it a good idea to limit charging to 80%? I also use the above setup on the Dell laptop but would like try the Dell Power Management app that includes setting of high and low limits, if I could find it. I've since upgraded that old Dell laptop from win7 with a clean install of Windows 10. If I recall correctly, Dell UK had the best selection where-as Dell Canada and Dell USA were preaching the delusional hard line that the Dell battery charging/Power Management was perfect. Unfortunately, I was unable to download a functional Power Management app from Dell before they disappeared. My old laptop is a Dell Studio 1747 and about the time that Dell was releasing various power management apps, the battery/charger was giving me significant grief. Now it shows 0% wear and I've verified this with the command line 'powercfg /energy'. When I started using the BatteryBar app it indicated a battery wear of about 7-9%. I would guess the battery most likely stayed on charge for most of that time. This MSI GP-72 started its life as a demo unit for a few months but the deal was too good to ignore. This setup is a bit more manual but is almost flawless. If I plan to go mobile or just a periodic battery maintenance, I might allow the high charge to reach 98%. This way I can once in a while allow the charge level to exceed 90% without disabling the high alarm. I keep the Battery Limiter app pinned to my taskbar and not set to start with Windows. The info widow above is produced with a mouse-over on the taskbar icon. I have the BatteryBar app on my taskbar and set to start with windows. I believe that allowing a Li ion battery level to fall below 25% will promote a premature failure.īatteryBar Pro: Windows Battery Life Tracker I set the critical battery level to 25% and the critical battery action is set to hibernate. If I have stepped away from the PC, the Battery Limiter alarm will yell at 43%, alerting me to come back and energize the charger. This is my indicator to switch on the power bar/charger easily within reach. I've also tweaked the settings in the Advanced Power options menu.īy setting the low battery level in the Advanced Power options menu to 45%, the display dims and produces a low battery notification from Windows. Battery Limiter allows you to set high and low alarm limits, with visual and or audio indicators. I use an app called Battery Limiter along with BatteryBar free. Which monitoring software do you use? I’ll give it a go ![]()
