FAQs
Q: How can I check if the laptop battery is compatible with my laptop?
1) Find the "Model Name" label on the front of your laptop under the keyboard (some are on the back) or the "Battery Model" label on the battery, then look for that model number in the Product Compatibility List on this website.
2) Compare whether the voltage and capacity of your original battery are consistent with ours, and then look at the big picture of our product to see if the interface and general shape are the same.
3) If you have any questions, feel free to 「Contact Us」.
Q: How to properly charge the laptop battery?
A: Since the current lithium-ion battery has no memory effect, you don't need to charge the new battery for 12 hours or more when using it for the first time, just fully charged. When the laptop is connected to an external power source, the battery will no longer be charged and discharged when fully charged, and will continue to use the external power source to supply power. If you frequently use external power, keep it off the battery several times a week to help extend the life of your battery. It should be noted that when using battery power, you should try to avoid running out of battery power. When the remaining power is 10%, you must connect to an external power supply.
Q: How should I maintain my laptop battery every day?
* Avoid completely draining the battery.
* Adjust the computer power options to "Energy Saver".
* Close some unnecessary battery-consuming applications.
* Turn down the brightness of the display as far as possible.
* When the outside temperature is too high, such as running large-scale applications, you should use a radiator to accelerate the heat dissipation.
* If the notebook computer is not used for a long time, the battery should be charged and discharged once a month and placed in a cool and dry place.
