Hello @sanjeev293200 .

Swollen batteries should be replaced and disposed of properly for functional reasons but do not present a safety concern. When replacing a swollen battery, do not dispose of the swollen battery with general household waste. Follow the laws and regulations in your area for battery disposal. HP recommends its customers to recycle rechargeable batteries.

Although swollen batteries generally do not represent a safety concern, HP recommends replacing them. For batteries that are still under warranty, contact HP support to request a replacement. For batteries that are no longer under warranty, contact HP to purchase a replacement.

If you cannot access the battery, contact HP support or an HP authorized service provider for battery replacement.

About the causes and cell swelling
Cell swelling is a condition that can occur with polymer cells used in some notebook batteries. Polymer cells are popular in the industry where thin cell design is desired.
Polymer cells can swell if they are damaged, not cared for or as a result of the manufacturing process. Swelling can occur due to prolonged low voltage, exposure to high temperatures, cell imbalance or other causes.
It can also happen when internal safety devices detect a battery fault condition. The deactivated battery may experience swelling in this state because the internal safety circuitry allows the cells to discharge in a safe low-voltage state.
