Motosikal dan Enjin Nasional Sdn. Bhd. (Modenas) was established on March 19, 1995, as part of the Malaysian government’s effort to develop the local two-wheel automotive industry. Modenas began operations in Gurun, Kedah, at a modern manufacturing complex equipped with R&D (Research and Development) facilities, engine testing, and vehicle assembly.
The Modenas Z15GT has gained wide attention and become a new icon in Malaysia, especially in the 150cc motorcycle segment. This model is Modenas’ “only child” in Moped 150cc category, designed specifically to meet the preferences of local riders who seek a combination of sporty style, strong performance, and affordable value.
The Z15GT features an aggressive design inspired by Kawasaki’s “Sugomi” DNA, the result of a close technical partnership between Modenas and Kawasaki Motors Ltd. Powered by a 149cc SOHC engine, the Z15GT delivers 12.5hp and 13Nm of torque, providing smooth and responsive rides both in the city and on highways.
In terms of design, the Z15GT comes with full LED lighting, a modern digital meter panel, and a 5.7L fuel tank that enhances its sporty character. The front telescopic suspension and KYB (Kayaba) rear monoshock ensure stable and comfortable handling.
Modenas Z15GT Battery Guide: Complete for New Riders
In this article, we share a complete guide to choosing the best battery for the Modenas Z15GT to ensure your motorcycle’s performance remains optimal even after long-term use.
We will help you understand important battery terms, the best types of motorcycle batteries, and trusted brands recommended for purchase.
Important Terms in Battery Selection
For new Z15GT owners, this might be your first time learning about motorcycle battery specifications. Here are several essential terms you should know.
Voltage (V)
Definition: The electrical potential difference of a battery. Importance: Ensures compatibility with the motorcycle’s electrical system. Using a battery with incorrect voltage may damage electronic components.
Ampere (Ah)
Definition: Measures the battery’s ability to store and supply electrical energy over time. Importance: A higher Ah value means the battery can supply power longer, important for motorcycles with complex electrical systems or long-distance rides.
Cold Cranking Amps (CCA)
Definition: Indicates the battery’s ability to start the engine in cold conditions. Importance: A higher CCA rating ensures the battery can deliver enough power to start the engine even at low temperatures, which is vital for consistent performance.
The Modenas Z15GT features a 149.5cc engine with an electric start system, making the correct battery selection crucial for smooth starting and stable idling.
Z15GT Battery Size: YTZ5S-BS
This battery type is commonly used in 150cc motorcycles such as the Yamaha Y15ZR and Honda RS150 because it offers stable performance, lightweight design, and easy maintenance.
Meaning of Battery Code YTZ5S-BS
Many riders wonder what this code means. Here is a simple explanation.
Y: Means Yuasa Standard (Japan). It follows the design and specifications of Yuasa batteries, an international standard for motorcycle batteries.
T: Means Top Terminal, where the positive (+) and negative (–) terminals are located at the top of the battery.
Z: Means Z-Series (High Performance), categorized as high-performance, compact, and sealed batteries that do not require water refilling.
5: Indicates nominal capacity of around 4.0–5Ah. The higher the number, the stronger and longer-lasting the battery.
S: Means Short Case (Compact Size), designed smaller but still powerful, suitable for modern motorcycles.
BS: Means Battery Sealed or Maintenance-Free, which refers to sealed dry batteries that require no water refilling.
Types of Motorcycle Batteries
Generally, motorcycle batteries are divided into three main categories.
1. Lead-Acid (Wet Battery)
Lead-acid batteries are the most common and affordable type. They come in two forms, conventional (wet) and sealed. Conventional batteries require regular maintenance and distilled water refilling, while sealed versions are maintenance-free.
Lifespan: 6 months to 1 year Maintenance: Requires distilled water refilling and should not be left unused for long periods.
Advantages:
- Affordable price
- Easily available in the market
Disadvantages:
- Requires regular maintenance
- Shorter lifespan compared to AGM and Lithium-Ion batteries
2. Absorbed Glass Mat (AGM/Gel Battery)
AGM batteries are maintenance-free lead-acid batteries designed to be durable and vibration-resistant. They provide stable performance under various conditions. AGM batteries are tightly sealed to prevent leaks and offer better cold-start performance.
Lifespan: 1 to 2 years Maintenance: No water refilling required, but avoid overcharging or leaving it unused for long periods.
Advantages:
- Maintenance-free
- Durable and stable
- Better cold-start power
- Leak-proof design
Disadvantages:
- Slightly more expensive than conventional lead-acid batteries
3. Lithium-Ion Battery
This type is known for being lightweight and high-performing. It charges faster and provides stronger cold-start power compared to traditional batteries. Lithium-Ion batteries also have a longer lifespan and require no maintenance.
Lifespan: More than 2 years Maintenance: Very durable but avoid overcharging or exposure to excessive heat.
Advantages:
- Lightweight and powerful
- Long lifespan
- Fast charging
- Maintenance-free
Disadvantages:
- Higher initial cost
