Tips

Before ordering, verify that your device's original battery has the same voltage (3.7V) and physical dimensions (approximately 25 x 15 x 5 mm). For best lifespan, avoid fully discharging the battery and store it in a cool, dry place when not in use. Always follow local regulations for battery disposal and recycling.
