A frozen battery case can absolutely swell if it has been cracked or if moisture has gotten inside. If the case is rusted, water can get in that way and cause it to swell.
A frozen battery case can swell if the liquid inside of it swells up. this can happen if the case has moisture inside of it or has been rusted out at all, allowing liquid to get in.
When it's really hot outside, the heat can case the battery case to swell. The heat can also drain the battery causing it to go dead, and can cause permanent damage.
How should I know :)
If you mean the battery is bulging or swelling then it may have been frozen. This will cause the electrolyte to freeze and bulge. A battery that is being or has been overcharged will also bulge or swell. A battery that is not secure and bounces around can have internal damage to the plates will can cause them to explode and bulge the battery. In any case I would immediately have your charging system tested at an auto parts store as your voltage regulator may be putting too much voltage into the battery. You should get a reading of 13.5 to 15.5 volts DC with the engine running at idle when you test at the battery posts. No matter what you find, replace this battery as it is dangerous and can explode at any time.
No, because if it is frozen it will not take a charge.
Usually from being discharged in below freezing weather. The water will freeze in a dead battery, expand, & swell the battery. This won't occur with a fully charged battery.
you can take out the battery....
Canned soups that have been frozen cannot be safely used. Freezing cans can cause them to swell and potentially harm the ingredients inside.
There is a crack in the battery case. Replace the battery.
Take out the battery, or wait until the battery runs out of power.
The cost for a battery case can vary greatly, depending on the model of phone and manufacturer. The average cost for an Apple IPhone Battery case on Amazon is $35.
positive and negative terminals and the battery case
Nano only! : if its 'on' and frozen (which happened to mine) wait till i t has no more battery and then charge it
