Recommendations

Use the battery with compatible Dell chargers and systems only; avoid exposure to extreme temperatures, moisture, or strong mechanical shock. For longest service life, avoid keeping the battery at full charge or in deep discharge for extended periods—store at roughly 40–60% charge if not used for months. Replace the battery if you observe substantial capacity loss, swelling, unusual heat, or charging anomalies, and follow local regulations for battery disposal or recycling.
