Don't Buy the Wrong Battery! 2025's Car Battery Brands Ranked Worst to Best

❌ NOT RECOMMENDED: UNDERPERFORMERS (Ranks 16--12)

These brands consistently underwhelmed in either reliability, lifespan, or warranty coverage. Some are budget options, but the long-term cost of jump-starts or early replacements makes them poor choices for most drivers.

16. EverStart (Walmart)

Walmart's house brand is easy to find and very affordable---but it's built for price, not performance.

The basic Value series struggles with cold starts and fades quickly under daily use.
The higher-tier Maxx line is AGM, but still falls short compared to DieHard or Duralast Gold.
Several users report inconsistent quality across batches.

Cold-weather performance: Weak
Warranty: 1--3 years (pro-rated)
Verdict: Skip unless you need a quick temporary replacement.
