The Victron GEL Deep Cycle Battery 90Ah is engineered for superior deep discharge performance and offers a significantly longer overall lifespan than standard lead-acid batteries. These high-quality models comply with European CE and American UL specifications, are housed in a flame-retardant ABS enclosure, and come with the worldwide 2-year Victron Energy warranty.
The Victron GEL battery uses VRLA (Valve Regulated Lead Acid) technology, where the electrolyte is immobilized as a gel, making the battery maintenance-free.
Increased Lifespan: Compared to AGM batteries, GEL models generally offer better durability in both 'float' (trickle charging) and intensive 'cycling' (discharging/charging) use.
Design Life: These batteries have an expected design life of 12 years under normal use.
Deep Discharge Capacity: The 90Ah nominal capacity is optimized for long-duration power delivery (measured at a 20-hour discharge rate), making them ideal for systems that are regularly deeply discharged, such as in RVs, boats, or off-grid applications.
Nominal Capacity & Discharge Characteristics
The nominal capacity of 90Ah for Victron Deep Cycle batteries is based on a 20-hour discharge (a discharge current of 0.05C). Please note that the effective capacity decreases as the discharge current increases. The included table illustrates this effect.
