Leoch Battery XP12-350

Leoch Battery XP12-350 – Ultra High-Rate VRLA AGM Industrial Battery

The Leoch Battery XP12-350 (also available in flame-retardant casing as the XP12-350FR) is a high-performance valve-regulated lead-acid (VRLA) battery engineered with advanced Absorbed Glass Mat (AGM) technology. Purpose-built for critical uninterruptible power supply (UPS) units, high-rate emergency backup, and data center power cabinets, the Leoch Battery XP12-350 delivers optimal energy density and rapid power discharge performance.

As shown in the product image, the battery features a compact, heavy-duty container equipped with integrated carrying handles for easy transportation and rack installation. It utilizes T6 M6 threaded copper-alloy insert terminals to ensure minimal internal resistance and high current conductivity during high-rate discharge events. With a long service life rating of up to 10–12 years in standby float applications, this battery provides stable energy storage under demanding power conditions.

Key Features of the Leoch Battery XP12-350

Ultra High-Rate Discharge Optimization: Specifically designed to supply massive wattage output (up to $370.3text{ W/cell}$ at a 15-minute discharge rate) during short-duration utility power outages.
Advanced AGM Technology: Utilizes high-porosity glass mat separators to absorb electrolyte fully, preventing acid leakage and making the battery completely maintenance-free.
Rugged ABS Container Construction: Encased in high-impact ABS material (with optional UL94 V-0 flame-retardant rating) that withstands mechanical shock, vibration, and thermal stress.
Low Internal Resistance & Low Self-Discharge: Features an internal resistance of approximately $4.0text{ m}Omega$ and self-discharge rate of less than $3%$ per month at $25text{ °C}$ , preserving charge during storage.
Low-Resistance Copper Terminals: Uses heavy-duty M6 threaded copper alloy terminals for reliable connections and minimal voltage drop under heavy electrical loads.
Environmentally Sealed Safety Vents: Equipped with one-way explosion-proof safety valves that automatically regulate internal gas pressure while preventing ambient air ingress.

Common Applications and Industrial Usage

The high power-to-volume ratio and rapid discharge capabilities of the Leoch Battery XP12-350 make it a primary choice for critical backup infrastructure:

Data Centers & Server Rooms: Serves as high-rate energy storage for critical multi-kVA UPS systems protecting server arrays.
Hospitals & Testing Laboratories: Powers emergency backup systems for life-support apparatus, clinical testing instruments, and emergency lighting.
Telecommunications Infrastructure: Supplies standby power to central switching offices, cellular base stations, and network control centers.
Financial & Industrial Emergency Systems: Integrates into bank data networks, power generation plants, and industrial control cabinets.

Installation Guidelines and Best Practices

Safety Precaution: VRLA batteries produce hydrogen gas under overcharge conditions. Install batteries in well-ventilated enclosures away from open flames or spark sources.

Torque Tightening Limits: Secure all busbar and cable terminal bolts to $5.0text{ to }7.0text{ N}cdottext{m}$ ( $44text{ to }62text{ in-lbs}$ ) using an insulated torque wrench to prevent terminal post damage or loose high-resistance contacts.

Float Charge Compensation: Adjust the float charge voltage by $-20text{ mV/°C}$ for string operating temperatures above or below $25text{ °C}$ to maximize service life and prevent thermal runaway.

Rack Clearance: Maintain at least $10text{ mm}$ ( $0.4text{"}$ ) spacing between individual battery blocks inside cabinets to permit ambient cooling airflow.
