Interstate Batteries remains an independent, family-owned company headquartered in Dallas, Texas. Founded in 1952 by John Searcy, it’s currently led by third-generation family members under the parent company Interstate Battery System International. While they don’t manufacture batteries themselves, they collaborate with global partners like Clarios (formerly Johnson Controls) to produce proprietary AGM and lithium-ion batteries under their brand. Notably, their 72V golf cart batteries utilize LiFePO4 cells from tier-1 Asian suppliers, with quality control managed through their Texas R&D center. Pro Tip: Always verify authenticity using their online serial number checker—counterfeit Interstate packs often lack proper thermal management systems.
Why Interstate Golf Cart Batteries Are a Top Choice
How does Interstate ensure battery quality without manufacturing?
Interstate enforces strict OEM partnerships and multi-stage testing. Their technical team audits facilities quarterly, requiring ISO 9001 certification and UL compliance. For example, their golf cart batteries undergo 23 performance checks including 72-hour thermal cycling at -20°C to 60°C. Transitioning to quality control, Interstate’s Dallas lab uses AI-driven predictive maintenance algorithms to flag cell inconsistencies before assembly. Pro Tip: Look for the blue “Triple Verified” stamp—it indicates cells passed capacity, cycle life, and safety tests simultaneously.
| Quality Metric | Interstate Standard | Industry Average |
|---|---|---|
| Cycle Life (LiFePO4) | 4,000+ cycles | 3,200 cycles |
| Voltage Tolerance | ±0.5% | ±1.2% |
What’s the warranty structure for Interstate batteries?
Interstate offers tiered warranties: 36 months for automotive AGM, 18 months for lithium packs. Their pro-rated replacement formula deducts 8% monthly after first year. Practically speaking, a failed 72V golf cart battery at 25 months would get 62% credit toward replacement. Warning: Warranty voids if charged below -10°C—use their temperature-compensated chargers in cold climates.

FAQs
No, they source A-grade LiFePO4 cells from Panasonic and CATL, then customize BMS and casing in-house for specific applications like marine or RV use.
Can I service Interstate batteries myself?
Only authorized dealers can reset the BMS—tampering triggers permanent lockout. Their 72V packs require professional balancing every 500 cycles using CANbus-enabled tools.
