Key Features

Supex Underground Battery Box, UBB series, is specifically designed to solve the problems of waterproof, ventilation, steam discharge which may possibly occur during the working of the batteries in actual project operation.

Maintenance-free peration and non-leakage

Deep Cycle battery has a special sealed and valve regulated the construction, which constructed differently than the traditional flooded battery. So there is no need to inject distilled water or any other liquid during the whole service life of the batteries.

All the acid inside the battery is suspended in a formulated non-woven glass mat separator and it is absorbed in the manner. This construction ensures leakproof during normal operation.

Low self-discharge, long shelf life, wide operation temperature Range

Special paste formula, over dimensioned negative plate, optimized. Exceptional Deep Discharge Recovery. High Quality and High Reliability.

A wide range of temperature operating range is suitable for different areas. TPD series batteries can be used in wide temperature range from -15°C to 50°C.

Copper Terminals and ABS container making battery better

Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric conductivity. ABS material increase the strength of battery container.
