Overview

The Yuasa YUAM624B4 YT14B-BS is a maintenance-free AGM battery designed to deliver dependable power while simplifying upkeep. Its compact, spill-resistant form fits a wide range of vehicles and equipment, with the electrolyte stored separately for activation when you’re ready.

Maintenance-free design and activation

• Maintenance Free: no water additions required during normal use; periodic charging is advised if the battery sits unused for long periods.
• Advanced lead-calcium technology helps maintain stable electrolyte density, reducing the rate of capacity loss over time.
• Absorbed Glass Mat (AGM) separators keep electrolyte in place, making the unit nonspillable and valve-regulated to minimize water loss.
• Bottle Supplied (BS) packaging ships electrolyte separately; activation is completed by the end user when ready.
• Compact dimensions (7 1/8 in L × 2 3/4 in W × 5 3/4 in H) and a weight around 11.8 lbs support easy handling and installation.

Activation guidance: the acid container is designed for straightforward use. After pouring the electrolyte, allow the plates to saturate briefly before the first charge to help optimize performance and initial power delivery.

Performance and specs

• Capacity: 12 Ah at 10 HR rate
