Hearing Aid Battery Warehouse operates at 642 Third Avenue, Suite G, in Chula Vista's Third Avenue Village commercial district, providing audiological products and hearing aid services from the same address as Clear Choice Clinic since 2004. The clinic's hearing aid fitting and battery supply services coordinate with diagnostic referral pathways from otolaryngology practices including ENT Associates of San Diego for patients transitioning from audiometric evaluation to device selection. Located on Third Avenue between E Street and H Street, the practice sits within western Chula Vista's walkable commercial spine where Savoie Restaurant and Filippi's Pizza Grotto anchor the dining corridor . Age-related hearing loss management at this location serves residents of nearby senior communities including Fredericka Manor Retirement Community for whom amplification devices are part of ongoing quality-of-life maintenance. Device services encompass behind-the-ear and receiver-in-canal hearing aid programming with real-ear measurement verification, zinc-air battery inventory across sizes 10, 13, 312, and 675, and custom earmold fabrication using silicone impression material.
