Long-Life 2V AGM Battery for Telecom & Energy Storage
The SOETECK SY-VRLA Series 2V AGM Battery is engineered for industrial-scale critical power systems and large energy storage applications, combining ultra-high capacity with superior high-rate discharge performance. Purpose-designed as a premium replacement for traditional 2V flooded lead-acid batteries, it is perfectly suited for integration into high-voltage (48V/110V/220V) battery banks, fulfilling the rigorous power demands of utility-scale UPS systems, solar and wind energy storage installations, telecom central offices and grid peak-shaving systems. Constructed with heavy-duty lead-calcium-tin alloy grids and advanced AGM electrolyte immobilization technology, this battery completely eliminates acid stratification and leakage risks, and is optimized for floor-mounted installation in battery room setups with fully maintenance-free operation. Boasting a deep-cycle life of up to 1000 cycles at 80% DOD and an ultra-low self-discharge rate (<2% per month at 25°C), it delivers stable, long-lasting performance across extreme temperature ranges of -15°C to 55°C, positioning it as a cost-efficient, dependable power solution for industrial-grade critical power applications. Product Family
Product FeaturesUltra-High Capacity & High-Rate DischargeAvailable in capacities from 200Ah to 3000Ah, tailored for large-scale battery bank configurations. Supports high-rate discharge up to 5C (5×rated capacity) for short-duration peak power demands (e.g., UPS backup during grid failure), 2x higher than 2V gel batteries. The AGM fiberglass mat structure enhances ion conductivity, ensuring stable voltage output even under heavy-load industrial conditions. Sealed Maintenance-Free & Leak-Proof DesignIndustrial-grade ABS casing with vacuum-sealed AGM technology eliminates electrolyte watering/topping-up and acid leakage, supporting floor-mounted installation in battery rooms with no risk of corrosion to equipment.

FAQ1. What is the key difference between 2V AGM and 2V Gel battery?2V AGM batteries excel at high-rate discharge (5C vs. 2C for gel) and fast recharge (80% capacity in 6-8hrs vs. 10-12hrs for gel), ideal for industrial UPS with peak load demands. 2V Gel batteries
have lower self-discharge (<1% vs. <2%/month) and better
performance at 100% DOD (1200 vs. 800 cycles). AGM requires higher
float charge voltage (2.27-2.29V/cell vs. 2.25-2.27V/cell for gel)
but tolerates occasional overcharging better, making it more
suitable for dynamic load industrial scenarios. 2. What is the cycle life and service life of 2V AGM Battery?At 80% Depth of Discharge (DOD), cycle life is 1000 cycles (retains ≥80% capacity); at 50% DOD (standby use), it extends to
1800+ cycles; at 100% DOD, cycle life is 800 cycles. Under normal
operating conditions (25°C, float charge voltage 2.27-2.29V/cell),
the service life is 8-9 years (comparable to 2V gel batteries, 2.5x longer than standard 2V
flooded lead-acid). At 35°C, service life reduces to 5-6 years due
to accelerated grid corrosion. 3. What are the charging requirements for 2V AGM battery banks?For 2V AGM battery banks: (1) Float charge voltage: 2.27-2.29V/cell (25°C); (2) Cycle charge voltage: 2.32-2.35V/cell (25°C); (3) Max charging current: 0.2C (e.g., 40A for 200Ah
battery, 300A for 1500Ah battery). Temperature compensation:
-5mV/°C per cell (e.g., 2.22V/cell float charge at 35°C). Use
industrial-grade CC-CV chargers with AGM profile; avoid
undercharging (voltage <2.20V/cell) which causes sulfation and
permanent capacity loss. 4. How to connect 2V AGM batteries into high-voltage industrial systems?To build industrial high-voltage systems: (1) Series connection: 24
cells for 48V (2V×24), 55 cells for 110V (2V×55), 110 cells for
220V (2V×110); (2) Parallel connection: Max 6 strings in parallel
(vs. 4 strings for gel) for capacity expansion (e.g., 6×1000Ah
strings = 6000Ah total). Ensure all batteries are same model/batch,
voltage difference <0.03V before connection, and use thick
copper busbars (≥50mm² for 1000Ah batteries) to minimize resistance
and uneven charging/discharging. 5. What are the installation and maintenance precautions for 2V AGM batteries?Installation: (1) Install in well-ventilated battery room
(temperature 10-30°C, humidity 40-70%); (2) Floor-mounted with
anti-slip/anti-corrosion pads, minimum 15cm spacing between
batteries for heat dissipation; (3) Insulated copper cables
(cross-section ≥50mm² for 1000Ah batteries). Maintenance: (1)
Inspect terminal tightness every 3 months (torque 12-18 N·m); (2)
Clean surface with dry cloth (no water/chemicals); (3) Monitor BMS
data monthly (voltage, temperature, capacity); no
watering/electrolyte checks required (sealed design). 6. What industrial applications are 2V AGM batteries suitable for?2V AGM batteries are optimized for industrial-scale dynamic load scenarios: (1) Large UPS systems (100kVA+ data center/industrial UPS); (2)
Utility-scale solar/wind energy storage (grid-tied/off-grid power
plants); (3) Telecom central office power supplies (48V/220V backup
systems); (4) Grid peak shaving/valley filling energy storage; (5)
Marine/port heavy-duty power systems. They are not recommended for
small portable applications (12V AGM is better) due to large
size/weight. Have more questions about our Liquid Cooling Solutions?Contact Us Now
