DOD 12V Gel AGM Lithium Battery Lithium Ion Battery Leakproof
The SOETECK SY-VRLA Series 12V Gel Battery is your go-to choice for reliable, low-maintenance backup power in critical scenarios. Leveraging cutting-edge gel electrolyte technology, it delivers exceptional deep-cycle performance and 100% leak-proof operation — making it a superior alternative to outdated flooded lead-acid batteries. It seamlessly fulfills the steady power needs of UPS systems, communication base stations, solar energy storage setups, and emergency power supplies.
Built with premium high-purity lead-calcium alloy grids and thixotropic gel electrolyte, this battery eliminates acid layering and leak concerns, allowing flexible installation in any orientation (vertical/horizontal). With a deep-cycle life of up to 500 charge-discharge cycles (100% DOD) and a minimal self-discharge rate (<2%/month at 25°C), it offers a cost-effective, durable power solution that delivers long-term reliability and value for your standby and cyclic discharge needs.

Product Features

Advanced Gel Electrolyte Technology
Adopts thixotropic silica gel electrolyte that immobilizes sulfuric acid, eliminating acid stratification and leakage risks common in flooded lead-acid batteries. The gel structure enhances ion conductivity (≥100 mS/cm at 25°C) and thermal stability, ensuring consistent performance even under deep discharge (100% DOD) and extreme temperature fluctuations.
Maintenance-Free & Leak-Proof Design
Constructed with sealed ABS casing and one-way pressure relief valve, it requires zero watering or electrolyte level checks over its lifespan. The leak-proof design supports vertical/horizontal mounting (±90°), making it suitable for confined spaces in data centers, communication cabinets, and mobile power systems with limited installation flexibility.
