Yuasa YUAM720BH YTX20HL Factory Activated H Series AGM Battery | 18Ah, 310 CCA

Powerful, ready-to-use reliability for your ride

Meet the Yuasa YUAM720BH YTX20HL, a factory activated H Series AGM battery designed for dependable starts and steady power. It delivers up to 30% more cold cranking amps than many conventional batteries, giving you confident starts in cooler conditions and during demanding use. The fully sealed design reduces maintenance worries while preserving performance over time.

Built with advanced lead-calcium chemistry, this battery helps keep electrolyte gravity stable for longer, contributing to consistent performance without frequent checks. The design centers on safety and convenience: absorbed glass mat (AGM) separators keep the electrolyte in place, making the cell nonspillable, and the valve regulated system minimizes water loss and the need for refilling. The Factory Activated (FA) construction means the battery is filled with electrolyte, sealed, and charged at the factory so you can install and go with minimal setup.
