Tips

For best results, fully charge and discharge the new battery two to three times to calibrate the fuel gauge. Store the battery at around 50% charge if it will be unused for extended periods. Always use a compatible Dell charger to avoid damage. If your laptop shows a battery error after installation, try updating the BIOS or reseating the battery.
