Design & Performance
The gelled-electrolyte chemistry eliminates the need for watering and minimizes stratification. Thick plates and robust separators provide consistent discharge curves and long service life, even under partial-state-of-charge cycling. The 8G34-DEKA’s non-spillable design and UL-recognized construction make it ideal for enclosed or vibration-prone installations.
