VOLT POLSKA Opti AGM OPTI 12V 65 Ah Battery

The VOLT POLSKA Opti AGM OPTI 12V 65 Ah is a high-performance, maintenance-free AGM battery designed for deep cycle applications. With a nominal capacity of 65 Ah and a cold cranking current of 680A (EN), it delivers reliable power for marine, RV, solar, UPS, and auxiliary power systems. Its advanced Absorbent Glass Mat (AGM) technology ensures spill-proof operation, low self-discharge, and excellent cycle life.

Advantages

This battery offers a design life of 10 years at 25°C, with up to 300 cycles at 100% depth of discharge (DOD) and 600 cycles at 50% DOD. It features a low internal resistance of approximately 4.5 mΩ, enabling high discharge currents up to 650A for 5 seconds. The maintenance-free design eliminates the need for water refilling, and the immobilized electrolyte allows safe operation in any orientation except inverted.
