That's unusual indeed for a new battery. So you got the SR59 rather than the R59 (which did and does require electrolyte).

There are many ways to bring some life back to an old battery, but since this is a new battery you will want to call your vendor.

Trickle chargers are often not capable of charging a fully discharged battery. You can shine a flashlight through the battery case to be sure all cells are full to the top of the plates, then attach a quality battery charger with boost mode. Give it a couple of minutes on boost, then disconnect and read the voltage again. If the voltage has gone up, fully charge it in normal mode.
