What should I do if the new battery isn’t recognized at first?

Occasionally a replacement battery needs an initialization routine to report correct capacity to the system. Follow simple reinstall and cycle steps to help the battery register and reach full performance.

• Power down and reseat the battery, ensuring the connector is fully seated.
• If not recognized, discharge to about 5% (avoid 0%), then fully charge and repeat 3–4 charge/discharge cycles.
• Contact OUWEE support via your order page if issues continue; warranty covers defects.

How does capacity translate to real-world use for my laptop?

Rated at 60Wh (7820mAh) and 7.68V, this battery provides similar runtime to the original Lenovo pack under the same workload. Actual endurance depends on screen brightness, CPU/GPU load, background apps and wireless usage.

• Light tasks (web browsing, document editing) will yield several hours of operation.
• Heavier tasks (video editing, gaming) reduce battery life significantly.
• Power-saving settings and dimmer screen settings extend usable time between charges.
