A carbon black having a combination of properties with values in ranges selected to promote high conductivity, high hydrophobicity, and reduced outgassing in lead acid batteries while maintaining high charge acceptance and cycleability. The carbon black has a Brunauer-Emmett-Teller (BET) surface area ranging from 100 m2/g to 1100 m2/g combined with one or more properties, e.g., a surface energy (SE) of 10 mJ/m2 or less, and/or a Raman microcrystalline planar size (La) of at least 22 Å, e.g., ranging from 22 Å to 50 Å. In some cases, the carbon black has a statistical thickness surface area (STSA) of at least 100 m2/g, e.g., ranging from 100 m2/g to 600 m2/g.
