These plates undergo a critical curing process to ensure they neither become brittle nor mushy. Seastar Battery takes pride in its 10-day curing period for plates, surpassing the industry standard of 1-3 days. This meticulous approach enhances the longevity and resilience of the batteries.

Secure Interconnections:

Deep-cycle batteries consist of multiple 2-volt cells interconnected to achieve the desired nominal voltage (e.g., 12 volts). While conventional methods involve punching holes through plastic separators and bolting the cells, Seastar Battery employs an innovative technique called over-the-partition (OTP) interconnection. OTP welds link the cells without stressing them against the plastic partition, allowing for upward movement and minimizing the risk of dropped cells.

Importance of Battery Cases:

The battery case is a critical component that significantly impacts overall battery performance. Older battery cases made of rubber prompted the recommendation of not placing batteries directly on concrete, but modern cases have evolved. Automotive and some deep-cycle batteries often employ polypropylene (PPO) cases, which are not puncture resistant and vulnerable to heat-related failures. PPO cases can also experience moisture loss when valves open frequently.

Seastar Battery addresses these issues by utilizing ABS plastic cases. The epoxy seal between the lid and ABS case ensures robust security, preventing lid removal without tools. ABS cases are highly resistant to drops and punctures, offering exceptional durability. Moreover, higher psi settings on the valves reduce moisture loss, enhancing the battery’s lifespan.

Dispelling Discharge Myths:

There is a common misconception that deep-cycle batteries should not be discharged beyond 50% of their rated capacity. While it is advisable to follow manufacturers’ recommendations, reputable brands often allow discharge levels of at least 80% without compromising battery life. Seastar Battery goes even further by subjecting every battery in its DC Series to rigorous life cycle testing, guaranteeing their ability to withstand a 100% depth of discharge (DoD) without performance degradation.

Additional Features:


Seastar Battery’s commitment to excellence is evident in various aspects of its deep-cycle batteries.
