Hydrometer Reading for a Lead-acid Cell?

Acid cell typically has a sulphuric acid based electrolyte, so it is mostly water. As the hydrometer reports the ratio of the specific gravity of your specimen to that of pure water, you should expect seeing something slightly larger than 1. I therefore presume you meant 1.100 and 1.300.
Those values seem reasonable, refer to the table in here: http://batteryuniversity.com/learn/article/how_to_measure_state_of_charge.
