Equipment / Tooling
I showed the Captain my bulging/expanding Tablet battery on the bus from hotel to [the airport]. Along with the cockpit; we made a unanimous decision to leave the battery in [departure airport]; and to give the battery to the agent at the gate. I hope [the company] will take priority action to ensure the safety of the crew; passengers; and planes so that there will be no exploding batteries in our [company] tablets. This could be a onetime incident or a future human loss and financial nightmare at 40;000 feet in the air.
Air carrier Flight Attendant reported a company issued tablet battery was observed bulging during the bus ride to the airport.
