About this file
This document is a detailed product specification sheet for a Bright Way Group (BWG) battery model BW 12550 DC (12V55Ah), which appears to be related to a Pinellas County, Florida contract opportunity for Uninterruptible Power Source (UPS) Batteries, Traffic & Solar Flashers. The specification sheet provides comprehensive technical details about a 12-volt sealed lead-acid battery, including dimensions (229mm x 138mm x 211mm), weight (15.5kg), capacity ratings (55Ah at 20HR, 44Ah at 5HR), and operational temperature ranges from -15°C to 50°C for discharge and -10°C to 50°C for charging.
The battery specification includes advanced technical characteristics such as constant current and power discharge charts, internal resistance of approximately 7.5mΩ, float charging voltage between 13.50 to 13.80V, and a designed floating life of 10 years at 20°C. The documentation details the battery's performance across various temperatures, self-discharge rates (91% remaining capacity after 3 months), maximum charging and discharge currents, and construction materials including lead dioxide positive plates, ABS container and cover, and an AGM separator. The specification sheet is designed to provide potential government and municipal purchasers with comprehensive technical information to evaluate the battery's suitability for traffic control and uninterruptible power supply applications.
