• Matches OEM voltage and capacity: 14.8V, 41Wh for correct power delivery.

• Overcharge and overdischarge protection to prevent cell damage.
• Overcurrent and short-circuit safeguards for safe operation.
• Temperature control monitoring to help avoid overheating during use or charging.

How easy is installation and what support comes with the purchase?

Replacement installation follows the same steps as swapping any internal laptop battery — power down, remove the back cover, unplug and swap the old pack for the new one. Fancy Buying provides customer support through the listing, a 30-day full refund policy and a 12-month warranty for defects or functional issues.

Will performance match my original battery and what can I expect day-to-day?

Expect similar runtime and charging characteristics when the replacement is new and calibrated; actual battery life depends on workload, screen brightness and wireless use. The pack is rated for up to 500 recharge cycles, after which capacity will gradually decline—normal for all rechargeable laptop batteries.

• New-out-of-box capacity equal to 41Wh for close-to-original runtime.
• Up to ~500 recharge cycles before notable capacity loss.
• Performance varies with hardware load, power settings and age of the laptop.
