Yuasa YUAM62T7B YT7B-BS Maintenance Free AGM Battery with Acid Pack | 6.5Ah, 110CCA

Overview

Meet the Yuasa YUAM62T7B YT7B-BS AGM battery, a compact, maintenance-free power source designed for reliable performance. Its valve-regulated design helps prevent water loss, and the lead-calcium chemistry supports steady electrolyte stability over time. The battery ships dry with electrolyte stored separately in a bottle, letting you activate it when ready. This approach keeps handling simple and reduces concerns about spills during shipping or installation.

While it is designed for minimal maintenance, periodic charging is recommended if the unit sits unused for long periods. The result is a compact unit that balances sturdy construction with the flexibility of on-site electrolyte activation, yielding a practical option for small equipment, backup power, and light-duty automotive or recreational applications.

Key benefits

• Maintenance Free: no water to add during regular use; periodic charging advised when not in use.
• Calcium-based chemistry: lead-calcium technology helps maintain electrolyte density longer than traditional designs.
• AGM and VRLA: electrolyte absorbed in glass mats keeps the battery nonspillable and sealed.
• Bottle Supplied (BS): electrolyte is stored separately and added by the end user to activate the battery.
• Compact sizing: fits tighter spaces without compromising usable capacity or power output (150 mm L, 65 mm W, 93 mm H).

Real-world use and considerations

• Ideal for small vehicles, motorcycles, scooters, and light equipment needing a dependable, space-efficient power source.
• Useful as a backup or peak-load option where immediate, maintenance-free power matters.
• The dry-to-wet activation model can simplify shipping and storage until activation.
