Battery protection technology.

Exclusive battery protection technology can increase the number of cycles to over 5000! But this technology isn’t enabled by default. Follow the directions below to configure the settings to your needs.

  • Rechargeable battery technology explained

    Fully charging and discharging a Lithium-Ion battery wears them out faster (reduces the number of cycles, and maximum capacity).
    Battery protection technology won’t recharge until the power drops below the START percentage, and will then only charge to the STOP percentage. Lithium-Ion batteries are usually saturation charged to 100%, and have a lifespan of 300 to 1000 cycles. The number of cycles can be increased dramatically (over 5000 cycles) by limiting the charge limit (STOP) to less than 80%.
    If you use a Pure Sine Wave Power Bank, rather than your laptop battery most of the time, and set FlexiCharger to Start at 40% and Stop at 60%, you can maximize the longevity of your laptop battery.
    Try to avoid totally draining your laptop battery as much as possible. The difference between draining it to 20% rather than 10% is 500 cycles.
    Because lithium-ion batteries deteriorate while being stored, I recommend waiting to buy a new laptop battery until it is needed, or 12 years from the purchase of your laptop (after which it may become increasingly difficult to find the right battery for your model.), whichever comes first.
    There is also the probability that advancements in battery technology, being made by the electric car and solar home industries, will make their way to laptop replacement batteries in the coming years.
    If you do replace the laptop battery, it would be a good time to blow out the dust to prevent overheating and fan failure, and replace the CMOS battery too, otherwise you may eventually need to synchronize the clock each time you boot the computer.

I also recommend that you read my advice on using Pure Sine Wave Power Inverters and Power Banks (Click to open the accordion.) to maximize your laptops battery lifespan, and time away from an outlet.

FlexiCharger setup instructions:

Click for larger

Shutdown your laptop. (Start – Shut down)
Once your laptop is off, press the power button.
Immediately start tapping the (F2) key (to the right of the ESC key) about once a second until you see the BIOS screen.
(If Windows starts booting, let it finish, then shut down, and try again.)

Once in the BIOS, use the arrow keys to navigate through the menus.
(Arrow Right) (NOT the greater than > key) to move to the ADVANCED menu.
Hit the (ENTER) key on the Advanced Chipset Control menu.

Click for larger

Hit the (ENTER) key on the FlexiCharger menu.

Click for larger

(Arrow Down) to ENABLED and hit the (ENTER) key to enable FlexiCharger.

Click for larger

You will get a warning that FlexiCharger can cause inaccurate Windows battery meter readings after a few months.

Hit (ENTER) to close the warning.
To reset Windows battery meter, go back into the BIOS, and disable FlexiCharger. (Your start / stop settings will remain.). Unplug your power cord, boot into Windows, and play a long movie, preferably with your laptop display brightness setting at 100% to drain the battery fairly quickly. Once the computer shuts down due to the low battery, Plug the power cord back in, boot into Windows, and let the battery fully charge. Then follow the directions above to enable FlexiCharger again.

  • GUIDANCE ON FLEXICHARGER SETTINGS

    According to electric car industry studies, each 10% decrease in the Stop percentage will double the number of cycles of the battery. Lowering the Stop percentage from 100% to 70% should increase the cycles from 500 to 5500!
    If you will use a Pure Sine Wave Power Banks you can maximize the laptop’s battery lifespan, at the expense of the power bank.
    The power bank also has a higher capacity, 155Wh, than the laptop, 62 – 82Wh.
    If you can’t use a power bank, then you will want to increase the start percentage, and set the stop percentage according to your needs.
    Just dropping the Stop percentage to 90%, and Start percentage at 80% should double the lifespan of your battery.

(Arrow down) to Start Charge.

Hit   (ENTER) to open the Start Charge settings.

Click for larger

(Arrow up) to the Start percentage that you prefer (40% recommended if you’ll use a power invert & power bank).

Hit   (ENTER) to change the setting.

Click for larger

(Arrow down) to Stop Charge.

Hit   (ENTER) to open the menu.

(Arrow up) to the percentage you prefer (A maximum of 80% recommended to avoid saturation charging that stresses the battery. 60% is even better.)

Hit   (ENTER) to change the setting.

Click for larger

Hit (F4) to save changes and reboot.

Hit  (ENTER) to confirm.

Your laptop will now restart into Windows. It won’t start charging until the battery power drains to the Start percentage. It will stop charging when you unplug the charger, or when the battery power reaches the Stop percentage.
Windows battery power meter will become increasingly inaccurate, but the BIOS will charge the battery to the proper percentage. To reset the Windows battery meter, disable FlexiCharger. Unplug the charger, drain the battery (playing video helps drain it faster). When the system shuts down due to low battery power, plug the charger back in, Boot into windows, fully charge the battery to 100%, then reboot and enable FlexiCharger.
