This is a brief guide for the Li-ion battery replacement of Sony Vaio Duo 13.
In this guide, a swollen Li-ion battery is replaced with a new one as a demonstration.
Replacing the old or damaged Li-ion battery is not only improves the performance of the laptop, but also keeps the battery in a healthy state for safety, avoiding the risk of thermal runaway.
Step descriptions:
- Step 1: Check the appearance of the laptop before replacement
- Step 2: Check the status of the battery before replacement (optional)
- Step 3~11: Teardown the laptop until the Li-ion battery appears
- Step 12~13: Remove the old or damaged Li-ion battery
- Step 14~15: Replace the old double-sided tapes (optional)
- Step 16: Install new Li-ion battery
- Step 17~18: Stick back the plastic sheet and double-sided tape
- Step 19: Spacing fixing (optional)
- Step 20: Check the laptop after replacing the battery
- Step 21: Check the status of the battery after replacement (optional)
NOTE:
- There is a "destructive" teardown that cannot be restored to its original state in step 9.
- Steps 2 and 21 can be skipped when users don't want to know the status of the battery or don't have the software.
- Steps 14~15 and 19 can be skipped when old double-sided tapes still provide sufficient stickiness.

This is an optional step. This step can be skipped when users don't want to know the battery status or don't have the software.
-
Check the "cycle times" by battery software.
-
Suggested software: (1) BatteryInfoView, (2) BatteryMon.
-
Background: The number of "cycle times" depends on battery usage. It usually > 0. A Li-ion battery usually has "cycle times" about 500~1000. REF: https://doi.org/10.31224/osf.io/swcyg
-
For example: BatteryInfoView shows that "Number of charge/discharge cycles" is 306 (red box). BatteryMon shows that "Charge cycles" is 306 (blue box).
