Redway Battery’s F36690A is a 36V 690Ah LiFePO4 forklift battery engineered for Class I/II electric forklifts. It replaces 36V lead-acid systems with 4,000+ cycles at 80% DoD, delivering 2-3X lifespan. Key features include modular design for partial charging, IP65 waterproofing, and CAN bus communication. Operates from -20°C to 60°C with built-in BMS for overvoltage/thermal protection.

What are F36690A’s core technical specifications?
The F36690A operates at 36V nominal voltage with 690Ah capacity (24.8kWh). Built with 112 LiFePO4 cells in 12P14S configuration, it supports 500A continuous discharge (1,000A peak). Dimensions: 1300x700x800mm with 420kg weight—40% lighter than equivalent lead-acid. Charging requires 36V LiFePO4 chargers (45A recommended), achieving 0-100% in 4 hours via CC-CV.
Deep Dive: Designed for 8-hour shifts in multi-shift warehouses, the F36690A’s modular architecture allows partial recharging during breaks without memory effect. Unlike lead-acid’s 50% usable capacity, LiFePO4 safely discharges to 20% SOC. Technical Tip: Use CAN bus integration for real-time monitoring—SOC accuracy is ±3% vs. lead-acid’s unreliable voltage-based estimates. For example, a logistics center using F36690A cut energy costs by 62% through opportunity charging. But how do temperature extremes affect it? The BMS actively balances cells above 45°C while limiting discharge current below -10°C.
How does F36690A outperform traditional lead-acid forklift batteries?
F36690A provides 2,500 full cycles versus lead-acid’s 1,200 at half-depth discharge. Energy efficiency reaches 95% (lead-acid: 70-80%), reducing warehouse kWh costs. No acid spills or hydrogen gas risks comply with OSHA 1910.178(g).
Deep Dive: Transitioning from lead-acid to F36690A eliminates watering, equalization charges, and ventilation costs. A 2023 study showed 18% productivity gains since operators no longer wait for battery swaps. Technically, LiFePO4’s flat discharge curve maintains consistent lift speeds even at 30% SOC. Pro Tip: Retrofit older forklifts by confirming motor controller compatibility—some Curtis models need firmware updates for Li-ion voltage ranges. Consider this: A lead-acid battery loses 15% capacity yearly, while F36690A degrades <2% annually under proper 25°C storage.
| Metric | F36690A | Lead-Acid Equivalent |
|---|---|---|
| Cycle Life | 4,000 | 1,500 |
| Charge Time | 4h | 8h |
| Operating Cost/Year | $720 | $2,300 |
Which forklift models is the F36690A compatible with?
The F36690A fits 36V electric forklifts from Toyota, Crown, Hyster, and Yale with battery compartments ≥1250mm length. Common matches include Toyota 8FGCU25 (3.5T capacity) and Hyster E45XM (4.5T). Adapters available for DIN tray connectors.

Deep Dive: Compatibility extends beyond physical dimensions—software integration is key. Crown SC 6000 series trucks require J1939 CAN protocol activation for battery communication. Practically speaking, retrofitting a 2018 Jungheinrich ETR 235 needs terminal adapters (part #F36-JU-2024) to interface with Euro-style connectors. Real-world example: A PepsiCo distribution center successfully deployed 38 F36690A units across their Yale GP050MX fleet. Always verify your forklift’s maximum open-circuit voltage—legacy Linde controllers might misinterpret LiFePO4’s 43.2V as overvoltage.

What safety certifications does the F36690A hold?
F36690A meets UL 2580, UN38.3, and CE standards. Flame-retardant casing (UL94 V0) withstands 130°C. BMS includes ISO 26262 ASIL-C functional safety for fault detection.
Deep Dive: Beyond certifications, safety engineering focuses on failure redundancy. The multi-layer BMS has separate ICs monitoring temperature, voltage, and current—if one fails, backup systems maintain protection. For instance, during a thermal runaway test, cells vent gases through pressure valves while the BMS cuts output within 800ms. Unlike some Li-ion packs, F36690A uses LiFePO4’s inherent non-combustible chemistry. Pro Tip: Always request the Material Safety Data Sheet (MSDS)—it details proper fire suppression methods (Class D extinguishers not required).
How does F36690A handle fast charging?
Supports 1C charging (690A) with liquid-cooled cables, reaching 80% SOC in 45 minutes. Built-in ΔT monitoring prevents cell divergence >2°C during high-rate cycles.
Deep Dive: Fast charging requires infrastructure upgrades—standard 480V 3-phase outlets and 60kW chargers. The BMS uses coulomb counting for precise SOC management during rapid cycles. However, consistently charging at 1C reduces cycle life by 15%; warehouses should reserve fast charging for peak periods. For context, a 2024 BMW plant study showed 20-minute opportunity charges during driver changes extended operational uptime by 3 hours daily.
| Charging Rate | Time to 80% | Cycle Life Impact |
|---|---|---|
| 0.5C | 90min | None |
| 1C | 45min | 15% reduction |
| 2C | 22min | 40% reduction |
What’s the ROI when switching to F36690A?
Typical ROI is 18-24 months via energy/ labor savings. A $28,000 F36690A vs. $12,000 lead-acid becomes cost-effective after 1,800 cycles.
Deep Dive: Hidden savings include 8% lower warehouse HVAC costs (no hydrogen venting needed) and eliminating battery rinse-down labor. Calculator example: For 3-shift operations using 2 lead-acid batteries per truck ($24k/5 years), switching to one F36690A ($28k/10 years) saves $116k per forklift over a decade. Remember: Factor in your local electricity rates—LiFePO4’s 95% efficiency vs. lead-acid’s 70% slashes kWh costs by 35%.
