Frequently Asked Questions (FAQ)

How do I confirm if this battery is compatible with my laptop? The most reliable method is to check the part number printed on your original battery or the model number on the bottom of your laptop. If your device lists FLK644A, DPQ3212, or DPQ3925, this battery is the perfect match for your hardware.

Does the new battery require a „break-in“ period or special activation? Modern Lithium-ion batteries do not suffer from the „memory effect.“ While you can use the battery immediately, we recommend fully charging it to 100% and then discharging it to around 10% during the first 2–3 cycles to calibrate the internal power management system for the most accurate percentage display.

What is the expected lifespan of this replacement battery? Under normal usage conditions, this battery is designed to maintain high capacity for 300 to 500 charge cycles. Depending on your usage patterns, this typically translates to 2–3 years of reliable service.

What does the 12-month warranty cover? Our warranty covers any manufacturing defects, including the inability to hold a charge, sudden capacity drops, or communication errors with your laptop. We prioritize your safety and will provide a swift replacement should any issues arise.
