Frequently asked questions

• Q: Is this an authentic Lenovo battery? A: This is a high-quality aftermarket replacement battery designed to fit Lenovo Y50-70 and Y50-80 laptops. It provides reliable power and is engineered to match the original battery’s dimensions, electrical connections, and performance characteristics. It is not an official Lenovo-branded battery, but it is designed to meet or exceed the original’s functionality.
• Q: What is the expected runtime? A: Runtime varies with screen brightness, workload, and battery health. The replacement battery is intended to restore near-original runtime for typical daily use, including web browsing, office tasks, multimedia, and moderate gaming. For battery-intensive sessions, expect similar endurance to the original battery when it was new, with gradual decline as any Li-ion cell ages.
• Q: How long does charging take? A: Charging time depends on the charger and current battery health. Using a standard Lenovo-compatible charger, a full charge typically takes a few hours. Modern laptops optimize charging to balance speed and longevity, so you may notice slower top-off behavior as the battery ages, which is normal.
• Q: Can I use this battery while plugged in? A: Yes. Like most Li-ion laptop batteries, you can operate the notebook while it is connected to power. To maximize battery health and cycle life, allow the system to manage charging cycles according to its built-in protection circuitry and firmware.
• Q: Do you offer warranty? A: Many listings provide a warranty period, commonly 12 months or longer, depending on the retailer. Check the product page for exact warranty terms and coverage details, and keep the receipt or order confirmation for easy service if needed.
