Shuangdeng 6-SPB-75 – Super Power Lead-Carbon Battery | SPB Series Platform
Engineering Background
The Shuangdeng Group (双登集团), founded in 1969 and headquartered in Jiangsu, China, is one of Asia’s largest advanced battery manufacturers with ISO 9001 / ISO 14001 certification and a dedicated R&D center for lead-carbon electrochemistry. The SPB (Super Power Battery) series represents Shuangdeng’s flagship lead-carbon platform, engineered specifically for high-rate partial-state-of-charge (HRPSoC) duty cycles where conventional VRLA batteries fail prematurely.
Product Positioning
The 6-SPB-75 is a 12 V / 75 Ah monobloc lead-carbon battery designed for procurement engineers who require a drop-in VRLA replacement with significantly extended cycle life, superior charge acceptance, and reduced total cost of ownership in renewable energy storage, UPS, and industrial backup applications.

Proven Application Environments
- Renewable Energy Storage – Solar PV off-grid and hybrid systems requiring deep-cycle tolerance and fast recharge from intermittent sources.
- Telecom & Data Center UPS – Rack or cabinet backup power where high charge-acceptance reduces generator runtime.
- Industrial Backup Power – PLC control panels, SCADA systems, and emergency lighting requiring reliable standby capacity.
- Electric Vehicles & AGVs – Low-speed EVs and automated guided vehicles benefiting from lead-carbon’s high-rate discharge capability.
- Marine & Off-Grid – Remote installations where maintenance-free operation and wide temperature tolerance are critical.
Engineering Advantages
- Carbon-Enhanced Negative Plate – Activated carbon additive suppresses sulfation, the primary failure mode of conventional VRLA, extending service life by 2–3× in HRPSoC duty.
- Superior Charge Acceptance – Lead-carbon chemistry accepts charge 3–5× faster than standard AGM, reducing charge time and generator fuel consumption in hybrid systems.
- Deep Discharge Recovery – Recovers reliably from >80% depth of discharge, making it suitable for applications with irregular charge cycles.
- Maintenance-Free VRLA Design – Sealed AGM construction eliminates electrolyte topping, reduces installation footprint, and permits any-orientation mounting.
- Wide Thermal Tolerance – Operates across −15 °C to +50 °C without derating, suitable for outdoor enclosures and tropical climates.
- Drop-In Compatibility – Standard 12 V monobloc form factor and M6 terminals ensure direct replacement of existing VRLA installations without rewiring.
System Architecture & Signal Flow
In a typical solar-storage architecture, the 6-SPB-75 is wired in series/parallel banks to achieve the required system voltage (24 V, 48 V) and capacity. The lead-carbon negative plate acts as a pseudo-capacitor during high-rate charge pulses, absorbing energy that would otherwise cause gassing and grid corrosion in standard AGM cells. During discharge, the carbon matrix provides additional electron pathways, sustaining voltage under high-rate loads. A compatible MPPT charge controller should be programmed to the Shuangdeng SPB float/equalization voltage parameters listed above to maximize cycle life.

Technical FAQ
Q: What is the difference between lead-carbon and standard AGM?
A: Lead-carbon batteries incorporate activated carbon into the negative active material, which dramatically reduces sulfation and improves charge acceptance. The result is 2–3× longer cycle life in partial-state-of-charge applications compared to standard AGM.
Q: Can the 6-SPB-75 replace my existing 12V 75Ah VRLA battery?
A: Yes. The 6-SPB-75 uses a standard 12 V monobloc form factor with M6 bolt terminals, making it a direct drop-in replacement. Verify physical dimensions against your battery compartment before ordering.
Q: What charge controller settings should I use?
A: Set float voltage to 13.5–13.8 V and equalization voltage to 14.4–14.7 V at 25 °C. Consult Shuangdeng’s official datasheet or contact Konmask.com for application-specific charge profiles.
Q: Is this battery suitable for cold climates?
A: The 6-SPB-75 operates down to −15 °C for discharge. For charging in sub-zero environments, ensure the charge controller applies temperature-compensated voltage (typically −3 mV/°C/cell).
Q: What is the minimum order quantity?
A: Single units are available. Volume pricing applies for orders of 10+ units. Contact us for project pricing.
