Need help finding the right battery

Trying to find a replacement battery for a MacBook Air (13in 2017), Model A1466, EMC 3178. The bottom panel says 14.85V, but I can't find a battery over 7.6V. Is that normal? saw someone asked the same question in June of 2022, but the battery they were referred to didn't say it was compatible with this model. Any help would really be appreciated.
