Yuasa YTZ4V Maintenance Free AGM 12 Volt Battery - YUAM724ZV - YSAYUAM724ZV

The Yuasa YTZ4V Maintenance Free AGM 12 Volt Battery (YUAM724ZV) is a compact, factory-activated powersports battery engineered for small-displacement motorcycles and off-road bikes. As one of the most trusted names in motorcycle battery technology, Yuasa Battery built the YTZ4V around advanced AGM (Absorbent Glass Mat) construction — delivering reliable cold cranking performance without the hassle of adding acid or performing pre-charge maintenance before installation. Whether you're replacing a worn-out OEM unit or upgrading to a sealed, spill-proof design, the Yuasa YTZ4V is a proven choice for riders who demand dependability on the trail or the street.

Key Features & Benefits

• Factory Activated & Maintenance Free: The YTZ4V ships fully charged and sealed — no electrolyte filling, no initial charging ritual required. Simply install and ride, saving you time and eliminating the guesswork that comes with conventional flooded batteries.
• AGM Technology: Absorbent Glass Mat construction keeps electrolyte suspended in the glass mat separator, making the battery completely spill-proof and safe for any mounting orientation. This also improves vibration resistance — a critical advantage for off-road and trail applications.
• Advanced Expanded Plate Technology: Yuasa's expanded plate design yields greater starting power per kilogram compared to conventional lead-acid batteries, meaning you get strong, confident cranking from a smaller, lighter package.
• Compact & Lightweight Form Factor: The YTZ4V's small dimensions make it ideal for tight battery compartments found on youth and small-displacement motorcycles where space is at a premium.
• 12V / 3Ah Capacity: Rated at 12 volts and 3 amp-hours (10-HR rate), this battery is sized correctly for the electrical systems of the bikes it's designed to serve — providing adequate reserve capacity without over-engineering the application.
• Yuasa Battery Quality: Yuasa is a globally recognized OEM and aftermarket battery supplier for powersports, with decades of manufacturing expertise behind every unit.

Frequently Asked Questions

Q: Does the Yuasa YTZ4V come pre-charged and ready to install?
A: Yes. The YTZ4V is a factory-activated, maintenance-free battery. It arrives fully sealed and charged, so no acid filling or pre-charge is necessary. Install it and go.

Q: What bikes does the YTZ4V fit?
A: Confirmed fitment includes the Honda CRF125F, CRF125FB, and CRF110F. If your bike is not listed, reach out to our fitment team with your year, make, and model before purchasing.

Q: Is this battery truly maintenance free — do I ever need to add water or electrolyte?
A: Correct — the AGM design permanently seals the electrolyte inside the glass mat separator. There are no caps to open and no fluid to add over the life of the battery.

Q: Can I mount this battery in any orientation?
A: AGM batteries like the YTZ4V are spill-proof by design, which gives them significantly more mounting flexibility than conventional flooded batteries. Always confirm your specific bike's battery tray orientation, but the sealed construction eliminates leakage concerns associated with traditional lead-acid units.
