Is a swollen battery dangerous?
Swollen batteries, while not common, are a significant risk. They are the result of too much current inside a cell of the battery, which causes a build-up of heat and gas. This could damage the lithium-ion battery causing it to overheat and burst into flames.

Why does my MacBook battery keep getting swollen?
As they age a number of factors can contribute to the expansion of gases inside the battery. According to Professor Don Sadoway, Professor of Materials Chemistry at MIT as quoted on TekRevue, overcharging, such as in the event of a failed charge controller, is a pretty common cause.
What causes a battery cell to swell up?
The main cause for battery cell swelling is what is known as thermal runaway. If a cell reaches a certain temperature then a chemical in the cell (usually Cobalt Oxide for Lithium Ion batteries) starts an unintended reaction which is exothermic in nature (i.e. it creates heat).
Why are the batteries on my MacBook Pro so big?
Both of the machines have bulging batteries that are pushing out the back cover so that the machines do not sit on a flat surface properly. They said they could not replace the battery with a new one, but would be happy to sell me 2 new batteries.
