Product Description

 POWER UP YOUR RIDE WITH CUBWILL! 

    AGM (Absorbent Glass Mat) maintenance-free motorcycle batteries excel with leak-proof, spill-proof designs, ideal for vibration-heavy motorcycles. Their fiberglass mat absorbs electrolyte, enabling faster charging (20-30% quicker than flooded types) and high cranking power for reliable starts. They boast 3-5x longer cycle life vs. conventional lead-acid batteries, superior deep-cycle tolerance, and minimal self-discharge (1-3% monthly) for long idle periods. Resistant to extreme temperatures (-30°C~60°C) and corrosion, AGM batteries require zero maintenance-no water refilling or acid checks. Though costlier upfront, their durability and safety (no gas venting, safer installation angles) justify the investment for daily riders or high-performance bikes. Perfect for modern motorcycles prioritizing reliability, eco-friendliness, and hassle-free operation.

Conventional battery

MF battery with acid pack

Dry-charged batteries (Conventional Batteries) offer notable advantages: they are shipped without electrolyte, enabling extended storage (2-3 years) with zero self-discharge, simplifying transportation and inventory management. Once activated, they deliver high initial capacity and require minimal maintenance. However, drawbacks include the need for user-added electrolyte activation (risking performance issues if mishandled), 20-30% shorter cycle life compared to conventional wet batteries, and weaker recovery capability after deep discharge. Ideal for backup or intermittent use scenarios, they prove less cost-effective than regular batteries for daily riding with frequent charge-discharge cycles.

Essentially this is the ultimate "set it and forget it" battery. MF lead-acid motorcycle batteries with acid pack combine partial convenience and user control. offering better deep-cycle recovery than dry-charged types. They feature reduced gas emissions and spill-proof designs for safer handling. Though more durable than dry-charged batteries, their cycle life remains 10-15% shorter than fully maintenance-free AGM alternatives. They suit moderate-usage riders seeking balance between maintenance effort and longevity, but lose cost efficiency in high-demand scenarios compared to advanced sealed batteries.

GEL battery

Factory activited battery

Gel batteries (Gel VRLA) utilize silica-thickened electrolyte, ensuring leak-proof stability and vibration resistance-ideal for rugged riding conditions. Maintenance-free with a sealed design, they eliminate water refilling and prevent acid leaks or gas emissions. Advantages include 30-50% longer cycle life than flooded batteries, superior deep-discharge recovery, and stable performance in extreme temperatures (-20°C to 50°C). Their low self-discharge rate (3-5 times slower) preserves charge during prolonged storage. Though pricier upfront, their durability and safety (no spillage, reduced corrosion) make them cost-effective for frequent riders. 

Factory sealed and activated motorcycle battery, easy for shipping as common cargo. Spill-proofdesign means virtually no possibility of leaks never require refilling and aremaintenance free during the complete lifetime of the battery.These compact, lightweight AGM VRLA batteries deliver greater starting powelfrom a more volume efficient unit. With longer battery life due to improvedvibrations resistance with corrosion-preventive and high-pressure plates makethis an excellent choice for select Yamaha, and other applications.

Application

Application Scope of Lead-Acid Starter Batteries

   Lead-acid starter batteries are versatile power solutions designed for a wide range of combustion-engine equipment. Primarily engineered for motorcycles, these robust batteries also serve as reliable ignition sources for:

   - Three-wheeled vehicles (e.g., trikes, cargo rickshaws, and passenger trikes)

   - Agricultural machinery (tractors, harvesters, tillers, and irrigation pumps)

   - Seasonal equipment (snow blowers, lawn mowers, and leaf removers)

   - Utility vehicles (golf carts, ATVs, and compact industrial transporters)

   Featuring high cold-cranking amps (CCA) and vibration-resistant construction, they deliver instant power bursts for engine ignition while withstanding harsh operating conditions. Their adaptability to temperature fluctuations (-20°C to 50°C) makes them ideal for year-round use in diverse environments—from urban commutes to farmlands and winter landscapes.

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.
