Product Description

POWER UP YOUR LIFE WITH CUBWILL LEAD ACID OPZV SERIES BATTERIES

  OPZV batteries are a premium class of valve-regulated, sealed lead-acid (VRLA) batteries designed for extreme reliability and long service life. Their core technology combines tubular positive plates with gel electrolyte (silica-based), preventing acid stratification and enabling installation in any orientation.

  Key advantages include:

    Exceptional longevity: 15–20 years design life under float service.

    Deep-cycle resilience: 1,200+ cycles at 80% depth of discharge (DOD).

    Robust environmental tolerance: Operates from -30°C to 60°C with minimal capacity loss.

    Ultra-low self-discharge: ≤1.5% per month, allowing extended storage.

    Maintenance-free operation: >95% gas recombination efficiency and leak-proof construction.

  Commonly deployed in renewable energy storage (solar/wind), telecom backup systems, UPS units for data centers, and critical infrastructure like railways or offshore installations.

Motorcycle Starter Battery

Lead-Acid UPS Battery (VRLA)

OPZV (Gel Tubular) Battery

Purpose: Delivers instant high-current bursts to start engines.
Features & Advantages: Thin-plate design maximizes cranking amps (CCA) for reliable ignition. Maintenance-free AGM/EFB types dominate; compact size fits tight spaces. Advantages: affordable pricing, wide temperature tolerance, and quick recharge. Avoid deep discharges – significant capacity loss occurs below 50% DoD. Typical lifespan: 3–6 years.

Purpose: Provides sustained backup during power outages for critical loads.
Features & Advantages: Sealed VRLA (AGM/Gel) enables maintenance-free operation. Thick plates support deep-cycle use (minutes–hours runtime). Units are series/parallel stacked for voltage/capacity needs. Advantages: lower cost vs. lithium, proven safety, and tolerance for float charging. Limitations: 3–5-year lifespan, bulkier size, capacity degrades >25°C.

Purpose: Long-duration backup for critical stationary systems (e.g., telecom, renewables).
Features & Advantages: Tubular positive plates + gel electrolyte minimize degradation. Delivers 1,500+ cycles at 80% DoD and 20+ year design life. Superior deep-discharge recovery and heat/overcharge tolerance. Ideal for harsh or remote sites. Higher upfront cost but unmatched lifetime value. Requires voltage-specific charging.

Installation Instructions

New Battery Preparation

Verify specifications: polarity, dimensions, voltage (≥12.4V).
Clean the battery and ensure vent ports are sealed.
Transfer reusable components (vent tubes, terminal covers).
 
Vehicle Preparation

Clear debris from the battery tray to avoid damage.
Inspect terminals/hold-downs for corrosion (use hot water for minor buildup; seek professional help for severe cases).
Confirm alternator belt tension and charging system functionality.
 
Battery Installation

Secure the battery with hold-down clamps (avoid over-tightening).
Reconnect terminals in order: positive first, then negative.
Transfer protective components (e.g., vent tubes). Apply petroleum jelly sparingly to terminals on hard-rubber batteries.
Remove CMS and start the engine for testing.
For non-automotive equipment, follow manufacturer guidelines.
 
Key Safety Notes:

Disconnecting the battery may trigger door locks—keep keys accessible.
Always disconnect negative first, reconnect positive first.
Cover old battery terminals with caps to prevent short circuits.
