Recent investigations have revealed that several popular car battery brands fail to meet their advertised performance claims, affecting millions of drivers who rely on these products for their vehicles. These discrepancies not only lead to unexpected breakdowns but also raise questions about the reliability of the automotive battery industry as a whole. With car batteries being crucial for vehicle operation, consumers need to be informed about which brands might not deliver on their promises.

1. EverStart

EverStart batteries, widely available at Walmart, have been criticized for their short lifespan. Many users report that these batteries fail within two to three years, despite claims of long-lasting performance. The 2018-2022 Ford F-150 models, which often utilize EverStart batteries, have seen numerous complaints regarding sudden failures.

2. DieHard

DieHard, a well-known brand with a legacy of reliability, has faced scrutiny in recent years. Customers have reported issues with their batteries, particularly the DieHard Gold series, which are marketed as premium options. Some users found that these batteries underperformed in extreme weather conditions, especially in freezing temperatures.

3. AC Delco

The AC Delco brand, associated with General Motors, often promotes its batteries as durable and long-lasting. However, multiple reports indicate that models like the AC Delco Professional series have failed to meet expectations, with many consumers experiencing significant performance issues within the first year of use.

4. Odyssey

Odyssey batteries are marketed for their extended cycle life and deep discharge capabilities. However, several users have detailed experiences where these batteries did not hold their charge as promised, leading to repeated jump starts. Many consumers have expressed dissatisfaction with the longevity of Odyssey batteries in regular commuter vehicles.

Interstate Batteries is a brand recognized for its extensive distribution network, but that doesn’t guarantee quality. The Interstate Mega-Tron series has been known to have a high failure rate within the first two years. Drivers using these batteries in popular vehicles like the 2019 Honda Civic have reported starting issues and premature failures.

7. Bosch

Bosch batteries, touted for their innovative technology, have not been immune to criticism.

Exide batteries, once a staple in the automotive industry, have seen a decline in consumer trust.

Many drivers have expressed disappointment in the battery’s inability to hold a charge beyond the warranty period, with some failing as soon as 12 months after purchase. This has led to an increase in complaints from users of various models, including the 2021 Chevrolet Silverado.
