10.5/12.5mm High-Precision Battery Electrolyte Filling Manifold System

This product range consists of industrial-grade plastic multi-cell connected battery filler jugs, precision electrolyte dispensers, high-frequency filling syringes, and heavy-duty fluid return container portfolios. It is engineered primarily for automated battery assembly lines, industrial manufacturing workshops, automotive MRO maintenance centers, and commercial material handling fleets to quickly, safely, and symmetrically dispense diluted sulfuric acid or replenish distilled water into specialized battery systems.
Instead of using traditional slow funnels that require continuous manual holding and risk hazardous chemical splashbacks, our containers introduce synchronized multi-spout layouts, integrated multi-state physical balance legs (including round-to-square and rigid locating composites), and high-frequency plunger flow controls. The nozzle outer diameters span seamlessly from a micro-pouring 5mm up to a heavy-duty 23mm, with center-to-center pitches engineered to mirror international battery manufacturers' engineering blueprints perfectly. Operators can safely execute multi-cell simultaneous symmetric filling with a single pour. Molded from premium high-acid-resistant Polypropylene (PP) or crystal-clear, high-rigidity Polycarbonate (PC), these tools directly address workshop efficiency and strict Western health and safety (OSHA/HSE) compliance.
Specific Applications (Detailed Breakdowns)
Supported by a comprehensive structural matrix of technical pitches and nozzle configurations, our container lineup serves distinct global B2B industrial applications:
Standard Commercial Vehicles & Medium-Sized Energy Storage Arrays: Deploys our newly updated 9.8mm Spout O.D. Core PC Block (GT7-A / GT14H / GT16H / GT20H / YHD-12 / GT24H Series). Tailored for the most high-turnover mid-sized lead-acid power cells, this block delivers highly precise equal pitch layouts (21mm / 23.6mm / 27.5mm / 28mm / 32.5mm). Heavy-duty round-to-square transition balance legs (ranging from 21mm to 30mm height) securely straddle the battery casing lips for clean 40ml, 50ml, and 65ml volumetric pouring.
Automotive Start-Stop (AGM/EFB) Assemblies & Leoch L0 Formats: Deploys the Leoch L0 Custom Series (PC Material). Engineered with a dual-tiered 10.5mm & 12.5mm composite spout O.D. and an exact 21.5mm equal center pitch. It features 8mm anti-slip legs designed for fast, synchronized 6-hole simultaneous charging into 80ml high-rate start-stop cells.
Ultra-Compact Cells & Specialty Precision Instrumentation: Deploys the GT2.5-3-E, GT4-3-G, and GT5A-3-F Lines (PC Resin). Offering ultra-fine 5mm and 8mm spout outer diameters, buyers can source ultra-dense 11.5mm equal spacing, 20-15-18-15-20mm variable pitches, or 14-22-14-22-14mm cross graduated layouts to match micro-apertures.
High-Frequency Volumetric Single-Cell Control & Extraction: Deploys our Plunger-Type Start-Stop Filling Syringe (70ml / 14.5mm O.D.) and Heavy-Duty Liquid Return Cylinder Series (325ml / 23mm heavy O.D.). Injection-molded from 100% virgin PP, these allow individual cell targeting, acid extraction, and forced fluid overflow recycling.
Heavy Logistics Forklifts, Golf Carts, & Data Center Standby UPS Arrays: Deploys the heavy-duty 6-30 Big-Hole (14.8mm O.D. / 43.5mm pitch) and 3-100 High-Capacity (11mm O.D. / 42mm pitch / 475ml per cell) rows to handle massive liquid replenishment loops efficiently.
OEM / ODM Customization Capabilities
Tooling Pitch & Structural Re-Engineering: Equipped with our own CNC tooling workshop, we can modify core mold inserts to adjust axis pitches, spout outer diameters, multi-row staggered layouts, or balance leg configurations based on your technical battery blueprints.
Corporate Brand Identity & Color Matching: Casing frames, handles, and caps can be molded to match your specific corporate Pantone color schemes, with brand logos crisp laser-debossed or embossed onto the plastic surfaces.
Heavy-Duty Cross-Border Packaging: All products are packaged in 5-ply reinforced corrugated export-standard cartons featuring thick interlocking grid partitions to prevent surface scratching or pressure warping during long trans-oceanic transit.
