Q4: What is the “Bridge Battery” system?

• Dual Batteries: Your laptop has an internal battery AND this external rear battery.

• Extended Runtime: Using both batteries together provides maximum battery life.

Q5: How do I install this battery?

Installation is simple and requires no tools:

1. Ensure the laptop is on AC power or has enough charge in its internal battery.

2. Slide the battery release latches on the bottom of the battery.

3. Insert the new battery into the rear compartment until it clicks into place.

4. The laptop and Windows will automatically recognize the new battery.

Q6: What warranty do you offer?
