About this file
This document is a detailed product specification sheet for the Bright Way Group (BWG) BW 12550 DC (12V55Ah) battery, associated with a Pinellas County, Florida contract opportunity for Traffic UPS, Batteries, Traffic & Solar Flashers. The specification sheet provides comprehensive technical details for a 12-volt sealed lead-acid battery designed for various applications, with a 55 Ah 20-hour capacity, dimensions of 229±2mm x 138±2mm x 211±2mm, and an approximate weight of 15.5 kg.
The battery features a 10-year designed floating life, operating temperatures ranging from -15°C to 50°C for discharge, and specific charging characteristics including float charging voltage of 13.50 to 13.80V and cyclic charging voltage of 14.50 to 15.00V. The specification sheet includes detailed technical graphs and tables covering discharge characteristics, constant current and power discharge performance, charging characteristics, cycle life, temperature effects, and self-discharge rates. The battery is constructed with lead dioxide positive plates, lead negative plates, ABS container and cover, AGM separator, and a copper terminal, making it suitable for municipal traffic and infrastructure applications.
