Product Description

CUBWILL Lead-Acid UPS Batteries: The Reliable Backup Powerhouse

  Lead-acid batteries are the most common and cost-effective energy storage solution for Uninterruptible Power Supply (UPS) systems. Primarily using Valve-Regulated Lead-Acid (VRLA) technology, they are sealed and maintenance-free. The two main VRLA types are Absorbent Glass Mat (AGM), where the electrolyte is held in glass fibre separators, and Gel, where the electrolyte is immobilized in a silica gel.
  Their core function is to provide instantaneous backup power during mains electricity failures (outages, sags, surges), preventing critical equipment like servers, network devices, and medical instruments from shutting down abruptly. This gives users vital time to save data or perform orderly shutdowns until power is restored or generators start

Motorcycle Lead-Acid Starter Battery

Lead-Acid UPS Battery (VRLA)

Purpose: Provides high bursts of power to start motorcycle engines.
Features & Advantages: Designed for shallow-cycle use with thin, high-surface-area plates delivering high cranking amps (CCA) instantly. Robust construction withstands engine vibration. Maintenance-free AGM/EFB variants dominate; traditional flooded types require periodic watering. Compact size fits tight spaces. Advantages include reliable cold-start performance, affordability (~$30-$100), and wide temperature tolerance. Not suitable for deep discharges - frequent draining drastically shortens lifespan.

Purpose: Delivers sustained backup power during mains outages for IT/industrial equipment.
Features & Advantages: Valve-regulated (VRLA) sealed design (AGM/Gel) enables maintenance-free operation and safe indoor use. Thick plates optimize deep-cycle capability for prolonged, stable discharge (minutes to hours). Units are series/parallel connected to match UPS voltage/runtime needs. Advantages include proven reliability, lower upfront cost vs. lithium-ion, and tolerance for long-term float service. Trade-offs: heavier/bulkier, 3-5-year typical lifespan, and performance declines in high heat.

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.
