Thank you for purchasing a rechargeable laptop battery from KingSener.

   Our battery was tested and checked well before shipment. Under the normal usting condition,the life of the lithium battery is about 800-1000 time of cycles, so that usually as far as possible to use the fast end (5-7%) in charge, the average use time is 5 to 8 years.

If the battery won’t charge, or doesn’t work properly after installation, there are some causes:

  1.Could be caused by battery loose. Please remove the battery and try to install more than once.
  2.May be due to conductive material damaged which the laptop motherboard and battery anode and cathode contact position, you can try to confirm it with your original battery.
  3.Check whether the battery drive is in normal condition, if not, download the corresponding driver software to update.
  4.Take out the battery and press the power button for about 15 seconds to consume the internal residual power (Do not connect the power cord), and then reinstall the battery. You can try several times.
  5.Try using a new adapter,make sure you install the battery in the correct way

  Turn off the laptop and disconnect the power adapter before installing the new battery; if you’re not sure how to install it correctly, ask for help at your local maintenance shop or consult us.

Activate the new battery’s optimal capacity

  For first use, it is recommended that you charge a new battery for 6-12 hours, then unplug the laptop from the power source to allow it to discharge to around 3%. And then recharging it again, repeat this process 2-3 times. This will help the laptop’s power management system to indicate accurate battery capacity and remaining time.

Daily maintenance for laptop battery

  We suggest that you do the above battery activation at least once every two months, as it will extend the working time and life of your battery. If you won’t be using the battery for a month or longer, we suggest you charge the battery to 50%-80% capacity and then remove it from the laptop, store it in a clean, dry place until you need it again.

Warning: Do not expose the battery pack to direct sunlight and other heat sources, and keep it away from water and other liquids at all times.

The battery’s working time - if unplugged from mains power - depends on factors such as:

The amount of time that you’re using it for
