Acer makes believe you have control over your system like battery charge limit. However, this app keeps on saying it is initializing and the battery charge limit keeps resetting. For some reason, this happens a few times every week. Yet Acer has done nothing to improve this crappy app and it is very annoying. Will buy some other laptop brands in the future. Acer sucks. 0 Answers The theory of limiting charging of a battery to preserve lifespan is the hoax, not proven and pure anecdotal. Lithium-IO batteries contain a SMART chip that diverts the adapter power after it reaches 100% charge, perfectly OK to leave you laptop plugged in 24/7. ACC has pitfalls in Windows11, hangs a lot and the driver updating interferes with Windows WAU app. The PC restore option in ACC is useful if you did not yet Clean installed Windows. I uninstalled ACC. BTW most laptop brands have this battery charge limiting app, it is industry wide and in all bloatware present. 1 Assistance by AcerHow to Limit Battery Charge in Windows 11 [Tutorial]
A battery’s lifespan is related to its chemical age, which is more than just the length of time since the battery was assembled. A battery’s chemical age results from a complex combination of several factors, including temperature history and charging pattern. All rechargeable batteries are consumable components that become less effective as they chemically age. As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance. Find out more about iPhone battery and performance and how to maximise battery performance and lifespan. Optimised Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. It is available when Charge Limit is set to 100 per cent. When the feature is enabled, your iPhone will delay charging past 80 per cent in certain situations. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimised Battery Charging will only activate when your iPhone predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your iPhone is still fully charged when unplugged. When Optimised Battery Charging is active, a notification on the Lock Screen states when your iPhone will be fully charged. If you need your iPhone to be fully charged sooner, touch and hold the notification and then tap Charge Now. Optimised Battery Charging is on by default when you set up your iPhone. To change your charging option with iPhone 15 models and later, go to Settings > Battery > Charging and choose an option. You can choose a charge limit between 80 per cent and 100 per cent in 5 per cent increments. When the charge limit is 100 per cent, Optimised Battery Charging is available. To change your charging option with iPhone 14 models and earlier, go to Settings > Battery > Battery Health & Charging and turn Optimised Battery Charging on or off. Turning off charging optimisations can increase wear on your battery and reduce its lifespan. With iPhone 15 models and later, if the charge limit is 100 per cent, you can also turn on Optimised Battery Charging. Your iPhone has these settings by default. Your iPhone will charge to within a few percentage points of your chosen limit and then stop charging. If the battery charge level drops more than 5 per cent while connected to power, charging will resume, again charging to within a few points of your chosen limit. If iOS determines that a charge limit will help preserve your battery's lifespan, you'll see a recommendation.

This is very simple. But the problem is, that each battery has a limit of taking charge and being discharged. That is why we need a controller to control both the charge and discharge limit. Otherwise, the battery will be damaged.Charge controller A charge controller has a basic operation of sensing and switching the electrical connection between the solar panel, battery, and load. Although this mechanism differs from controller to controller (we’ll discuss this later) you can say this is some kind of switch-like relay switch. There is a switch between the solar panel and the battery andComments
