Reserve Power Batteries

OGi monoblocks

Sunlight OGi monoblocks are vented, low maintenance, lead-acid batteries with liquid electrolyte. They are ideal for applications of high current and short discharge times, such as UPS systems, meeting high safety requirements. They are also perfectly suited for longer duration discharges in telecom, utilities and power plants.

Sunlight OGi’s special rod plate design offers high energy density in a compact footprint, long service life and good cyclic capabilities in industry-standard container sizes. The vent design and the low antimony lead alloy reduce water topping-up intervals and maintenance costs. Robust transparent containers facilitate visual inspection and the high integrity terminal design maximizes operational safety and permits fast and easy voltage and internal resistance measurement readings.

The products are developed by SUNLIGHT’s R&D team which constantly designs and evaluates new innovative solutions to better meet market needs based on the latest technological trends, industry developments and market feedback.

SUNLIGHT’s products and services have gained international recognition by ensuring uninterrupted and reliable operations in a wide range of critical applications for a broad spectrum of industries, such as Telecom and Power networks.
