VRLA gel technology

Robust and reliable

Sonnenschein gel batteries are the most robust lead acid technology. The electrolyte is retained in gel for the ultimate in resilience, safety and reliability. They are the product of choice in applications requiring high integrity such as medical and military. They are particularly suited to cyclic applications such as mobility equipment, where they offer a lower whole life cost when battery replacement is taken into account.

Advantages include:

• Longer charged shelf life (low self discharge)
• Robust to over charge and deep discharge
• Excellent shock and vibration characteristics
• Excellent cyclic capability
• Excellent high current performance

Product classes include:

• A200: 1 -  6.5AHr, 5 year design life
• A500: 1 - 200AHr, 7 year design life
• Other ranges include: 12 year design life, up to 1600 cycles
