Foxsur Portable Battery Charger
User Manual - Models FPT-100 & FPT-200
Introduction
This user manual provides essential safety and operating instructions for the Foxsur FPT-100 and FPT-200 Portable Battery Chargers. These devices are 7-stage automatic smart battery chargers designed for 12V and 24V Lead-Acid and LiFePO4 batteries, including types like AGM, GEL, SLA, WET, EFB, and DEEP CYCLE.
The chargers feature microprocessor-controlled charging, temperature adaptation, and multiple protection mechanisms for efficient and safe battery maintenance.
(Visual description: Images show two identical battery chargers, one with a yellow top and one with a red top. Both feature a central digital display, mode indicator icons, and robust handles.)
Important Safety Instructions
WARNING:
- Always read and follow all instructions before using the charger.
- Ensure the charger is designed for your battery type (12V/24V Lead-Acid, LiFePO4).
- Check battery manufacturer specifications before charging.
- Provide adequate ventilation during charging to prevent ignition of explosive gases.
- Do not expose the charger to direct sunlight or high temperatures.
- Battery acid is corrosive; rinse skin/eyes immediately with water if contact occurs.
- Do not charge frozen, damaged, or non-rechargeable batteries.
- Never place the charger on the battery while charging.
- Exercise caution to avoid dropping metal tools onto the battery, which can cause sparks or explosions.
- Remove personal metal items (rings, watches, etc.) when working with lead-acid batteries.
- Do not smoke or allow sparks/flames near the battery during charging.
- Unplug the charger from the AC outlet before performing any maintenance or cleaning to prevent electric shock.
- This product is not intended for use by children or individuals unable to follow instructions without adult supervision.

7-Stage Charging Process
The charger utilizes a 7-stage charging process for optimal battery health:
- Stage 1: Battery Desulphation - Reverses sulfation damage.
- Stage 2: Soft Start Charging - Gently begins charging.
- Stage 3: Bulk Charging - Delivers maximum charge current.
- Stage 4: Absorption Charging - Maintains a constant voltage to fully charge the battery.
- Stage 5: Battery Test - Checks battery health after absorption.
- Stage 6: Recondition Charging - Recovers deeply discharged or sulfated batteries.
- Stage 7: Float & Maintenance Charging - Keeps the battery fully charged and healthy.

How to Begin Charging
- Verify the battery's voltage and chemistry.
- Ensure the AC power plug is connected to an electrical outlet.
- Press the mode button to cycle through and select the appropriate charge mode.
- Confirm that the battery clamps or eyelet terminal connectors are properly attached to the battery terminals.
- The mode LED will illuminate the selected mode, and the charging icon will light up (depending on battery health), indicating the charging process has started.
- The charger can remain connected to the battery at all times for maintenance charging.
