    • Q: How long is the battery life？
    Our battery was tested and checked well before shipment. Under the normal using condition, the life of the lithium battery is about 800-1000 times of cycles, so usually as far as possible to use the fast end (5-7%) in charge, the average use time is 5 to 8 years.
    Q: How do I find the right battery?
    Our search tool at the top of the website should give you the best results. Search by brand or part number to see if we have the right match for you.
    Q: Need you charge battery for 12 hours in the first use?
    No. Our batteries are lithium-ion batteries without memory effects. When the battery is fully charged, the charging current will be cut off automatically. Charging for 12 hours is wasting time.
    Q: How to check if this battery is compatible with my laptop?
    First, find out the part number of your old battery or the model name of your laptop (e.g. 'Dell Alienware M15X') and then match it with our product compatibility table. Second, please compare your old battery with our product images to make sure their shapes are the same. Finally, check the voltage (rating) is the same as the old one.
    Q: How should we test battery?
    1. Check if the customer has purchased the correct battery.
    2. Check the battery's appearance and interface.
    3. Test the battery's charger and recharge function.
    4. Charger the battery to 100% and recharge to 0% to get the real battery's capacity.
    5. Use Ev2300 to check the voltage difference of each group cell.
    6. Charger battery power of more than 30%.
    7. Package the battery carefully and send it out.
    Q: How to replace and install my battery?
    1. Turn your laptop over.
    2. Find out the battery release button lock.
    3. Press the battery release button, and pull the battery out of the laptop gently.
    4. Insert the battery into the slot. Push your battery to the laptop and secure it in place.
    Q: How to maintain my battery to extend its life?
    1. Tweak Your Built-In Power Saving Options.
    2. Adjust the brightness of your laptop display as much as possible within an acceptable range.
    3. Disable unnecessary programs that draw energy from your notebook.
    4. Keep your laptop and battery in a cool dry place.
    5. Avoid Full Discharge.
