SANTAK Castle Battery C12-26AH
High-Capacity Long-Life Storage for Mission-Critical Power Systems
Ensure seamless operational continuity during electrical dropouts with the heavy-duty Santak Castle C12-26Ah 12V UPS Backup Battery. Specially engineered to meet the demanding high-rate discharge performance benchmarks of the Santak Castle series, this industrial-grade cell is the premier choice for professional online UPS systems, telecom backhauls, emergency lighting arrays, and solar standby setups. Utilizing top-tier Valve Regulated Lead-Acid (VRLA) technology blended with a dense Absorbent Glass Mat (AGM) configuration, the Castle C12-26Ah delivers exceptional power retention and rock-solid cyclical stability without the hassle of routine maintenance.
Key Features & Benefits
- Completely Maintenance-Free Operation: Thanks to its advanced VRLA sealed design, internal gas recombination handles up to 99% of emitted oxygen, eliminating the need to top up water levels or check hazardous acid parameters.
- High-Efficiency AGM Grid Integration: Outfitted with thick, ultra-pure lead-calcium-tin alloy plate grids that significantly decrease internal resistance, enabling rapid current delivery and high-rate power output during unexpected power failures.
- Exceptional Cyclic Stability & Low Self-Discharge: Features a remarkably low self-discharge rate (under 3% per month at 25°C), ensuring the battery stays highly charged and combat-ready even over extended periods of standby storage.
- Rugged Flame-Retardant ABS Enclosure: Encased in a highly durable, impact-resistant ABS plastic housing that isolates internal active matrices from external mechanical vibrations, shocks, and elevated ambient temperatures.
- Safe, Leak-Proof Design: The spill-proof structure guarantees total protection against structural leaks or acid fumes, making it perfectly safe to install vertically or horizontally inside compact network cabinets.
- Superior Deep Discharge Recovery: Meticulously optimized to handle abrupt, deep power drains and recover its nominal storage capacity smoothly upon grid re-activation, lengthening overall operational service life.
