It might be bad, or not. The definitive tests are either using a battery hydrometer to measure the specific gravity of the electrolyte in each cell, or using an electric load test. I prefer the hydrometer test.

Yes, it's normal to bubble hydrogen gas while charging. It's normal to not get hot when charging at such low rates. The fact that your charger is not tapering its charging rate suggests the battery may not be capable of achieving a full charge condition.

Most any auto parts store will test your battery as a courtesy.
