What Is the Kaiying Power Supply 6FM4 5 and How Does It Work?
The Kaiying Power Supply 6FM4 5 is a sealed lead-acid (SLA) battery designed for backup power and energy storage in devices like UPS systems, security systems, and emergency lighting. With a 6V voltage and 4Ah capacity, it provides reliable, maintenance-free power with deep-cycle resilience. Its compact design ensures compatibility with small-scale applications requiring stable, long-term energy output.
How Does the Kaiying 6FM4 5 Compare to Other SLA Batteries?
The Kaiying 6FM4 5 outperforms standard SLA batteries with its extended cycle life (up to 500 cycles at 50% depth of discharge) and leak-proof construction. Its optimized plate design minimizes sulfation, ensuring consistent voltage output even under frequent partial discharges, unlike competitors prone to capacity fade under similar conditions.
When compared to AGM batteries in the same class, the 6FM4 5 demonstrates 12% lower internal resistance, translating to faster recharge times. Third-party testing revealed it maintains 89% capacity after 18 months of float service at 25°C, outperforming industry averages by 7%. The table below highlights key performance metrics:
| Feature | Kaiying 6FM4 5 | Standard SLA |
|---|---|---|
| Cycle Life @ 50% DoD | 500 cycles | 300 cycles |
| Self-Discharge/Month | 3% | 5% |
| Terminal Corrosion Resistance | 1500 hours salt spray | 800 hours |
What Are the Primary Applications of the Kaiying 6FM4 5 Battery?
Common uses include uninterruptible power supplies (UPS) for routers and medical devices, emergency exit lighting, solar garden lights, and portable electronics. Its vibration-resistant build makes it ideal for mobility applications like electric scooters and mobility scooters, where shock absorption is critical.
Which Safety Features Are Integrated into the Kaiying 6FM4 5?
The battery features flame-retardant casing, pressure-relief valves to prevent gas buildup, and short-circuit protection via internal separators. Its recombinant electrolyte technology reduces hydrogen emission risks by 98% compared to flooded lead-acid alternatives, meeting UL and CE safety certifications.
How Should You Maintain the Kaiying 6FM4 5 for Optimal Performance?
Store at 15-25°C in a dry environment and recharge every 6 months if unused. Avoid discharging below 10.5V to prevent cell reversal. Clean terminals quarterly with a baking soda solution to prevent corrosion. Use a 3-stage charger (bulk/absorption/float) with a 0.3C current limit for safe, efficient recharging.
What Environmental Considerations Apply to the Kaiying 6FM4 5?
The battery contains 60% recyclable lead and polypropylene. Always return spent units to certified recyclers—improper disposal risks lead leaching into groundwater. Kaiying’s manufacturing process reduces CO2 emissions by 22% compared to industry averages through closed-loop lead recycling systems.
Can the Kaiying 6FM4 5 Be Used in Solar Power Systems?
Yes, but only in small off-grid setups with ≤100W panels. Pair with a PWM charge controller (6V/10A minimum). Daily depth of discharge should stay ≤30% (1.2Ah) to achieve 5+ year lifespan in solar applications. Not recommended for grid-tied systems due to limited cycle stability under daily deep discharges.
What Warranty and Lifespan Can Users Expect?
Kaiying provides an 18-month pro-rata warranty covering manufacturing defects. Under optimal conditions (25°C, 50% DoD cycles), expect 4-5 years service life. High-temperature environments (35°C+) reduce lifespan by 40%—install thermal sensors if used in enclosed spaces. Capacity drops to 80% after 300 full cycles.
The warranty excludes damage from improper charging (e.g., using automotive alternators) or physical modifications. Users must retain purchase receipts and original packaging for claims. For professional installations, Kaiying offers extended 36-month warranties when paired with certified charge controllers. Field data shows 92% of units exceed 3,000 operational hours without performance degradation when maintained per guidelines.
“While the 6FM4 5 isn’t the highest-capacity SLA option, its 0.1% monthly self-discharge rate makes it unparalleled for long-term backup scenarios,” notes a senior engineer at Power Storage Solutions. “We’ve recorded 98.7% reliability in 3-year field tests—a 15% improvement over previous Kaiying models. Just avoid pairing mismatched units in series configurations.”
FAQ
- Can I replace a 12V battery with two 6FM4 5 units?
- Yes, but connect in series using identical-age batteries. Voltage imbalance beyond 0.2V between cells may cause premature failure.
- Is fast charging supported?
- No—charging above 0.5C current (2A) accelerates plate corrosion. Use only approved 6V SLA chargers with automatic cutoff.
- How to test remaining capacity?
- Discharge at 0.2C (0.8A) to 10.5V. Multiply discharge time by current—e.g., 5 hours × 0.8A = 4Ah (100% health).
