1. Company Overview
Founded in 1926 and headquartered in Fremont, Ohio, Crown Battery Manufacturing Company is a privately held US battery manufacturer with ISO 9001:2015 certified facilities. For nearly a century, Crown has manufactured deep-cycle batteries for industrial, motive power (forklifts, golf carts), renewable energy, and automotive applications. The company is known for its heavy plate construction — thicker plates with more active material than typical consumer batteries, delivering longer discharge times and greater deep-cycle tolerance.
Crown's market position is as an industrial-focused deep-cycle battery manufacturer with a reputation for durability. Unlike the LFP-focused brands in this guide (EG4, BYD, Pylontech), Crown spans multiple chemistries — flooded lead-acid (FLA), absorbed glass mat (AGM), and lithium iron phosphate (LFP) — allowing customers to choose the chemistry that fits their budget and application. Crown's FLA batteries are particularly valued in material handling and off-grid solar where upfront cost matters more than weight or maintenance.
2. Current Product Lines
Crown's deep-cycle battery lineup spans three chemistries:
- Flooded Lead-Acid (FLA) Deep Cycle — Crown's signature line, featuring heavy plate construction with Alpha Plus paste technology. Models include the CR-GC150 (12V 150Ah golf cart/RV battery) and the deep-cycle 6V and 12V industrial series. FLA batteries require periodic watering but offer the lowest upfront cost per kWh.
- AGM (Absorbed Glass Mat) Deep Cycle — Maintenance-free, spill-proof, vibration-resistant. Crown's AGM line uses an inline production process for consistent plate construction. Suitable for RVs, marine, solar, and golf carts. Vibration-resistant and can be mounted on their side.
- Lithium Iron Phosphate (LFP) — Crown's newer lithium line, targeting solar and energy storage applications. The CR-430 and related models offer LiFePO₄ chemistry with built-in BMS for residential and commercial storage.
- Industrial Forklift/Motive Power — Crown's largest segment: 24V, 36V, 48V, and 80V forklift battery packs (e.g., 24-125-13 48V 750Ah). Standard 5-year warranty. Used in material handling, aerial work platforms, and floor scrubbers.
3. Recent Releases (2025–2026)
- LFP expansion — Crown has been expanding its lithium iron phosphate product line to complement its established FLA and AGM offerings, targeting the residential solar storage market where lithium's maintenance-free operation and longer cycle life are increasingly demanded.
- AGM inline production process — Crown's revolutionary inline AGM COS (Cast On Strap) production process moves raw materials to finished deep-cycle batteries with improved consistency and efficiency.
- Automotive line updates — Crown continues to offer 5-year consumer warranties on standard automotive batteries and 6-year warranties on premium automotive lines.

5. Warranty & Cycle Life
Crown's warranty terms vary by chemistry and application:
- FLA deep-cycle: Typically 1–5 year warranties depending on application. Cycle life: 1,200+ cycles with proper maintenance (watering, equalization charges). FLA batteries can last several years with proper care.
- AGM deep-cycle: 3-year warranty (e.g., TE35-AES: 3 years or 1,200 cycles at 80% capacity retention). Up to 2,500 cycles, 10,000 hours of operation. Maintenance-free.
- LFP: 5–10 year warranty (varies by model). 6,000+ cycles at 80% DoD for LFP chemistry.
- Industrial forklift: Standard 5-year warranty.
- Automotive: 5-year (standard) to 6-year (premium) consumer warranties; 1–3 years for heavy-duty commercial.

| Model | Capacity | Voltage | Chemistry | Cycle Life | Price Range |
|---|---|---|---|---|---|
| Crown CR-GC150 | 150Ah | 12V | FLA | 1,200+ cycles | $200–$350 |
| Crown AGM Deep Cycle | 180Ah (210Ah C20) | 6V | AGM | 2,500 cycles | $300–$500 |
| Crown CR-430 (LFP) | 100Ah | 48V (51.2V) | LFP | 6,000+ @ 80% DoD | $1,500–$2,500 |
| Crown Industrial Forklift | 750Ah | 48V | FLA | 1,500+ cycles | $3,000–$6,000 |
7. Technical Comparison
| Metric | Crown FLA | Crown AGM | Crown LFP | Trojan T-105 (FLA) |
|---|---|---|---|---|
| Chemistry | Flooded Lead-Acid | AGM | LiFePO₄ | Flooded Lead-Acid |
| $/kWh (upfront) | Lowest (~$150–$250) | ~$250–$400 | ~$300–$500 | ~$150–$250 |
| Cycle life | 1,200+ cycles | 2,500 cycles | 6,000+ cycles | 1,200+ cycles |
| Maintenance | Watering required | Maintenance-free | Maintenance-free | Watering required |
| Weight (per kWh) | Heaviest | Heavy | ~50% of FLA | Heaviest |
| DoD | ~50% recommended | ~50% recommended | 80–100% | ~50% recommended |
Crown's advantage is chemistry choice and industrial durability: you can choose FLA for lowest upfront cost, AGM for maintenance-free convenience, or LFP for maximum cycle life and depth of discharge. The trade-off is that Crown's LFP line is newer and less established than dedicated LFP brands like EG4 or Pylontech, and FLA batteries require ongoing maintenance (watering, equalization).
8. BMS & Monitoring
- FLA/AGM: No BMS — lead-acid batteries do not require electronic management. Use a compatible charge controller or inverter with lead-acid charge profiles. Crown's AGM batteries require temperature-compensated charging (5mV per cell per °C).
- LFP: Crown's LFP batteries include a built-in BMS with cell balancing, over-current, over-voltage, and over-temperature protection. CAN/RS485 communication for inverter integration.
- HydroLink (FLA): Crown's deep-cycle FLA batteries are compatible with single-point watering systems that simplify maintenance.
- Monitoring: Via the paired inverter or charge controller. LFP models support CAN/RS485 communication for real-time battery status.
9. Installation Notes
- Orientation: FLA batteries must be placed upright — electrolyte will spill if tilted. AGM and LFP batteries are non-spillable and can be mounted on their side.
- Venting: FLA batteries produce hydrogen and oxygen gas during charging and require ventilation. AGM and LFP batteries are sealed and require no active venting.
- Temperature range: FLA: -20°C to +45°C storage. AGM: -40°C to +60°C operating. LFP: -20°C to +60°C discharge, 0°C to 50°C charge.
- Maintenance (FLA): Check electrolyte levels regularly. Add only distilled or deionized water. Fully charge before adding water. Compatible with HydroLink single-point watering systems.
- Charging (AGM): Use temperature-compensated charging. Select proper battery type (AGM or gel) on charger. Boost charge at constant voltage of 2.2V/cell with current limited to 20% of C20.
- Recycling: Crown lead-acid batteries are 99% recyclable through established closed-loop recycling infrastructure.
10. Frequently Asked Questions
Should I choose Crown FLA, AGM, or LFP for my solar system?
It depends on your budget and maintenance tolerance. FLA offers the lowest upfront cost but requires periodic watering and only allows ~50% DoD. AGM is maintenance-free and spill-proof but still limited to ~50% DoD. LFP offers the longest cycle life (6,000+ cycles), deepest discharge (80–100% DoD), and zero maintenance, but at the highest upfront cost. For off-grid cabins where cost matters most, FLA is common; for residential solar, LFP is increasingly the default.
How long do Crown flooded lead-acid batteries last?
With proper maintenance (regular watering, equalization charges, and avoiding deep discharges below 50%), Crown FLA deep-cycle batteries typically last 1,200+ cycles or several years of service. The heavy plate construction and Alpha Plus paste technology extend discharge times and cycle life compared to consumer-grade batteries.
Are Crown batteries made in the USA?
Yes. Crown Battery has been manufacturing batteries in Fremont, Ohio since 1926. The company is privately held with ISO 9001:2015 certified manufacturing facilities. As a US manufacturer, Crown products are well-positioned for Build America, Buy America (BABA) compliance on federally funded projects.
Do Crown AGM batteries require maintenance?
No. Crown AGM (Absorbed Glass Mat) batteries are maintenance-free — no watering required. They are spill-proof, vibration-resistant, and can be mounted on their side. However, they should use temperature-compensated charging and be kept within their operating temperature range.
Can I replace my lead-acid golf cart batteries with Crown lithium?
Yes. Crown's LFP batteries are designed as drop-in replacements for lead-acid batteries in many applications, including golf carts and solar systems. Lithium offers longer cycle life, deeper discharge, lighter weight, and zero maintenance. Ensure your charger or charge controller supports lithium charge profiles before switching.
