Interstate All Battery Center provides battery sales, testing, and warranty services. Experiences with customer service vary significantly among reviewers. Several positive reviews highlight helpful and good people who provide excellent service. Staff members are described as very nice and willing to help, including carrying batteries to cars. They are knowledgeable, able to test batteries, and honest, having saved one customer money by correctly identifying functional batteries. The team is also helpful with warranty claims, even for batteries purchased elsewhere, following proper protocols like overnight charging for accurate testing. However, other reviews report grim and unsettling customer service, describing some staff as having no soul, a depressing tone, and appearing uninterested in helping customers while talking amongst themselves. Some find the service lackluster and the prices high, especially for used batteries. The store tends to be busy, leading to short waits, but many find the service worth it. While they may not always have specific batteries in stock, they can often transfer items for next-day availability. Overall, experiences depend heavily on individual interactions, with some customers awarding five-star ratings and others being unimpressed.
