12V 500mA Floating-Smart Battery Charger (0.5A, 2.5mm x 5.5mm Center Positive) | Part# FC-1250B

The FC-1250B is a highly efficient, fully automatic 12VDC 500mA (0.5A) floating-smart charger designed exclusively for 12-Volt Sealed Lead-Acid (SLA) batteries. Engineered with a dual-color LED intelligent notification system, it prevents overcharging by automatically switching from a high-rate fast charge to a safe, continuous float (trickle) maintenance charge once the battery reaches capacity.

Key Features & Specifications:

• Intelligent Charging Control: Features a smart, dual-color LED indicator to easily track charging status:
  • RED LED: Fast Charge mode (operating at >25% of the maximum charge rate).
  • GREEN LED: Ready / Float (Trickle) mode (maintaining the battery at <25% rate).
• Output Performance: Constant 12VDC @ 500mA (0.5 Amp max output). Standard no-load voltage reading sits accurately at approximately 13.75VDC.
• Universal Input Compatibility: Supports a wide input voltage range of 100~240VAC, 50/60Hz (20W), making it ideal for both domestic and international deployment.
• Heavy-Duty DC Plug: Terminated with a standard 2.5mm x 5.5mm barrel plug featuring a center-positive (+) polarity configuration.
• Safety & Compliance: Industry-standard CuL Approved and RoHS compliant, ensuring rigorous thermal, voltage, and materials safety.

Important Application Notes:

• Battery Type Restriction: This charger is strictly designed for Sealed Lead-Acid (SLA) batteries only. Do not use with Lithium, NiMH, or NiCd batteries.
• Need Alligator Clips? If your battery terminals require direct clamping, this charger pairs perfectly with our DC Barrel Plug Adapter to Alligator Clips (Part# RC-Y2C). It easily converts the 2.5mm x 5.5mm DC male plug into red and black insulated alligator clips for simple, solderless battery connections.
