Yes. Several batteries don’t include blanket coastal exclusions in their current warranties, including the Tesla Powerwall 3, BYD Battery Box Premium, Sungrow HV and Sigenergy SigenStor, among others.

Warranty documents change over time though, and some include ambiguous language around corrosive environments that may apply in practice. Always review the current warranty document, and get written confirmation from the manufacturer if you’re in any doubt.
