⚙️ Fit Notes

• Confirm your original battery label shows RE03XL (or one of the listed replacement part numbers) before ordering.
• “REO3XL” is commonly a letter/number mix-up in listings; the intended model is typically RE03XL.
• This is an internal battery—installation requires removing the bottom cover. Use proper ESD precautions and disconnect power before service.
• If you’re doing other internal service while the laptop is open, consider using a quality thermal compound like Shin-Etsu G751.
