VRLA and Gel Technology - Modern Solutions for Longevity

One of the key advantages of this battery is VRLA (Valve Regulated Lead Acid) technology, which allows for the automatic release of excess gases, making battery use safe and maintenance-free. This system minimizes the risk of overheating or damage to the unit, which is crucial in long-term installations.
Additionally, gel technology (GEL), in which the electrolyte is fully gelled, provides better performance in cyclic operation and at extreme temperatures. This solution allows for long-term and deep discharge, which is extremely important for systems that require continuous power and reliability. Compared to other batteries, Victron Energy GEL is characterized by greater resistance to discharge and a lower risk of damage during intensive use.
Another important feature Victron Energy 165Ah 12V battery Is extremely low self-discharge, which is only 2% per month. This means the battery can be stored for long periods without losing its charge. This makes it an ideal choice for installations that don't operate year-round, such as photovoltaic systems, which may not operate in the colder months due to a lack of sunlight.
Its lifespan is also impressive - the battery lasts up to 1800 cycles at 20% discharge, 750 cycles at 50% discharge and 500 cycles at 80% discharge. In addition, the designed lifespan in FLOAT mode is up to 12 years, which makes investing in this battery bring long-term benefits, both financially and operationally.
