    Battery charge capacity

    I want to change the battery charge from 60% to 100%.

    "Full charge capacity" means the capacity that the battery is managing to achieve. It is not a limit set by Windows or anything else; it is merely a reading of what the battery can actually do. You can use the comparison of Full charge capacity with Design
    capacity to decide when to buy a replacement battery [I do the same regularly].

    Full charge capacity will always decrease over time as the battery wears out. This is a chemical phenomenon not a Windows-imposed characteristic.

    Windows display of "Fully charged [100%]" means - the battery is currently at 100% of what it is able to achieve. In other words, "Fully charged [100%]" is relative to Full charge capacity.

    Sometimes, you can find that cycling through the battery three times** can improve the Full charge capacity a bit.
    On at least one of my batteries, the maker recommends doing this every three months. But doing so is using up even more of its remaining life so you can complete this procedure only to find that you are worse off afterwards.

    ** In other words, loop through this three times -

    • remove the AC power
    • use up the whole charge by using the computer
    • recharge fully

    New battery not charging

    I have an Acer Aspire V3-771 laptop (which is three and a half years old) with its original battery. As the battery is not holding the charge for as long as it used to I decided to replace it. I inserted he new battery, which already showed a charge of 60%, and let it run down to the point when the laptop turned itself off. However, when I tried to recharge the battery, the battery icon showed "6% available, plugged in, not charging". I contacted the supplier of the battery and they sent me a new one. This showed an initial charge of 93% so, in view of my problem with the previous battery, I decided to try and charge it up to full capacity before letting it run down. But as soon as I tried this the battery icon showed "93% available, plugged in, not charging". So I unplugged the charger and again let the battery run down until the computer turned itself off. I plugged the charger in again but then got "6% available, plugged in, not charging". I have no problem charging the old battery, so can anyone please suggest what the problem might be? I have tried taking out the battery and unplugging the charger and holding down the power button for 30 seconds, but this hasn't worked. Grateful for any advice.

  4. Battery charge capacity


    I have a laptop where the Battery report tells me that the battery FULL CHARGE CAPACITY is much less than its DESIGN

    I would like to know if there is a way to reset this setting somehow so that Windows can try to fully charge the battery, instead of stopping the charge at what is currently known as the battery FULL CHARGE CAPACITY.

    Right now, the numbers are:

    5 441 mWh
    48 669 mWh

    which results in only a few minutes of battery usage.

    Using the CPUID HWMonitor tool, I can see that the battery charge actually stops at 5441 mWh, instead of continuing, and Windows report the battery as being 100% charged at that level, even if it is only at 11% capacity.

    So, can anyone provide a method to reset the battery FULL CHARGE CAPACITY to its DESIGN CAPACITY so that Windows can re-evaluate the true battery capacity, as if it was a brand new battery.
