AS10D51 Battery Step-by-Step Installation Guide

1. Unlock the Old Battery:
   Flip the laptop over. Locate the two sliding latches on the battery bay. Slide the “Lock” latch to the open position.
2. Release and Remove:
   Hold the “Release” spring-latch in the open position while simultaneously sliding the old battery out of its bay.
3. Insert the New Battery:
   Align the gold-plated connectors of the new HTJ AS10D51 battery with the pins in the laptop’s bay. Slide the battery in until you hear a firm “click.”
4. Secure the Latch:
   Slide the “Lock” latch back to the locked position to ensure the battery is held securely.
5. Calibration:
   Charge the new battery to 100%, keep it plugged in for 2 hours, then discharge it to 5% before recharging to 100%. This synchronizes the battery meter with the system.

💡 Pro Tip: To extend the life of your new AS10D51, avoid leaving the laptop plugged in 24/7 at 100% charge. Occasionally, discharging the battery helps maintain cell chemistry.

Q: How to identify if your battery is an AS10D51 / AS10D31 / AS10D75 / AS10D81?

A: Look at the underside of your original battery. You will see “AS10D51”, “AS10D31”, “AS10D75”, or “AS10D81” printed in the corner. This series is universally interchangeable among the models listed above.

Laptop Maintenance Tips: 

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run a battery to 0%, as this would shorten its usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. When fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
