What Is a Group Size 24 Battery?
How Does Clarios Produce EverStart Deep Cycle Batteries?
Clarios uses advanced absorbed glass mat (AGM) technology for EverStart deep cycle batteries, ensuring spill-proof designs and vibration resistance. Their production facilities adhere to strict quality standards, utilizing automated precision welding and pressure-formed grids to optimize plate durability. Batteries undergo rigorous testing, including charge/discharge cycles and thermal stress simulations, to meet Walmart’s performance benchmarks.
The manufacturing process begins with high-purity lead alloys, which undergo continuous casting to create uniform grid structures. Clarios employs computerized density monitoring during paste application, ensuring optimal active material distribution. Post-assembly, each battery undergoes a 72-hour formation charge to stabilize electrochemical properties. Production lines feature real-time quality audits, with sample units subjected to 500+ deep discharge cycles to validate lifespan claims.

Why Choose EverStart Over Competitors Like Optima or Interstate?
EverStart offers comparable cycle life to premium brands at 30% lower cost, backed by Walmart’s nationwide warranty support. Independent testing shows 15% faster recharge rates versus Interstate equivalents. Their exclusive Walmart distribution enables rapid warranty replacements, with 90% of claims processed in-store within 24 hours—a critical advantage for users in remote locations.
Field tests demonstrate EverStart batteries maintain 85% capacity after three years of seasonal RV use, outperforming many mid-tier competitors. The calcium-Silver hybrid grid alloy reduces sulfation by 40% compared to traditional lead-antimony designs. For marine applications, EverStart’s corrosion-resistant terminals withstand salt spray testing for 144 hours without failure—meeting MIL-STD-810G military standards.
| Feature | EverStart Marine | Competitor Average |
|---|---|---|
| Cycle Life (50% DoD) | 600 cycles | 450-500 cycles |
| Cold Cranking Amps | 800 CCA | 750 CCA |
When Should You Replace an EverStart Deep Cycle Battery?
Replace when capacity drops below 70% of original rating or voltage falls under 12.4V after 12-hour rest. Look for physical signs like terminal corrosion exceeding 40% surface area or case bulging. EverStart batteries typically last 3–5 years in marine use (100+ cycles annually) but may require earlier replacement in high-temperature environments above 110°F.
Where Can You Authenticate EverStart Battery Warranties?
Walmart’s warranty verification portal cross-references purchase date against UPC codes and manufacturing dates laser-etched on battery cases. Authentic EverStart batteries show matching date codes in Walmart’s inventory system—critical for claims. Counterfeit units often lack proper date stamp alignment, voiding warranty coverage immediately.
