Frequently Asked Questions
Q: How do I make sure this battery fits my laptop?

A: For the best performance, we recommend discharging the new battery to about 10%-15% (avoid draining it completely to 0%), then charging it uninterrupted to 100%. Repeat this cycle 2 to 3 times to fully calibrate the internal cells.
Q: What is covered under the 12-month warranty?
A: Our 12-month warranty covers any manufacturing defects, unexpected capacity loss, or charging malfunctions under normal, everyday use conditions.

Yes, in most cases. This is a common sign of a worn-out battery. A new compatible battery should restore normal portable use.
Many laptops limit charging to 80–95% to extend battery life. If it’s stuck much lower, the battery may be failing and should be replaced.
Check seating and contacts first. If the issue continues, the battery is likely faulty and replacing it will usually solve the problem.
