Open circuit voltage of 12.5 indicates a good batery. 13.7 volts would have been voltage with alternator charging ( nor a few seconds afterwards ). Need to keep an eye on why the electrolite levels are dropping though. PEter

If you buy an Autocraft Titanium battery be sure and check the cells electrolyte levels before installing. I stopped in an Advance Auto store to buy ATF on a Sunday evening about two months ago. The car wouldn't start when I left so I bought one of their Titanium A batteries. Saturday I serviced the car and checked the electrolyte levels in the battery. Two cells were dry and it required two to three ounces of distilled water to bring them up to the correct level. The other cells sp.gr. was in the red zone 11.50-11.75. After driving two days, the two cells I had added water to were still in the red zone but the other cells had come up almost to normal. I suspect these two cells were damaged by driving it two months with very low electrolyte. No one at Advanced Auto had ever heard of checking the sp.gr. or had any knowledge of what it meant, and they refused to give me a new battery. I checked the voltage when I serviced the car on Saturday and it was 13.7 volts. I checked it today and it was only 12.5 volts. I'm wondering if the battery might be drawing too much current and might have damaged the diodes in the alternator?
