A battery with surface charge has a slightly elevated voltage and gives a
false voltage-based SoC reading. To normalize the condition, switch on
electrical loads to remove about 1 percent of the batterys capacity or
allow the battery to rest for a few hours. Turning on the headlights for a
few minutes will do this. Surface charge is not a battery defect but a
reversible condition.

Never add acid. This would raise the specific gravity too high and cause
excessive corrosion.

Wiadomo, że jak wyparuje, to się dolewa wody, ale jeśli się wyleje (np.
reanimacja pękniętego akumulatora), to chyba można kwasu...
