Sealed AGM VRLA rechargeable battery NORDMARK 12V 7Ah with T1 (4.75 mm) terminals

Sealed AGM VRLA rechargeable battery NORDMARK 12V 7Ah with T1 (4.75 mm) terminals is a valve-regulated, maintenance-free lead‑acid battery designed for standby and backup power. Its absorbed glass mat (AGM) construction minimizes acid leakage and allows installation in multiple orientations. The compact 12V 7Ah format and T1 (4.75 mm) terminals provide a straightforward connection for UPS units, alarm systems, emergency lighting and small power supplies where a reliable rechargeable source is required.

Advantages

The battery’s VRLA design eliminates the need for electrolyte refilling and reduces maintenance. AGM technology delivers low internal resistance for efficient charge acceptance and stable power delivery during discharge. T1 (4.75 mm) terminals provide secure, widely compatible connections and simplify replacement or installation in confined spaces. Its compact sealed case offers vibration resistance and safe operation in standby environments.
