What kind of stuff would grow in your cells filled with acid?
The flooded lead-acid battery is not filled with acid, but an acid solution with a variable, but low %, amount of sulfuric acid(H2SO4). Yes, living things can survive a low % acid solution.
The reason lead-acid batteries freeze is that the sulfuric acid(H2SO4) is deposited on the plates in greater amounts related to the % of dis-charge.
The H2SO4 when in the water acts as anti-freeze. Lower % of acid in solution make it easier for the battery to freeze at higher temps.
A dead battery leaves the liquid as closer to pure water.
Frozen, not slushy, water can distort the plates and can be observed as a swelling of the battery case. Swelling tells you not to expect recovery of the battery.
