The device is a KickAss 12V 22 Amp 9-Stage Automatic Battery Charger, designed for charging 12V batteries to their optimum. It is controlled by a microprocessor and features a 9-stage charging profile.
Function Description:
The KickAss 12V 22 Amp Smart Charger is designed to charge various 12V battery types, including Lead Acid/GEL, AGM, and LiFePO4 (Lithium Iron Phosphate) batteries. It utilizes a microprocessor-controlled 9-stage charging process to ensure optimal charging and protection for the batteries. The charger automatically senses the battery's condition and provides the appropriate current and voltage.

- Charging Stages: 9 stages (Battery Diagnostic and Precharge, Desulphation, Soft Start, Bulk, Absorption, Recondition, Analysis, Float, Pulse).
Usage Features:
- Standard Charging Modes:
- Slow STD Mode: Max 4A charge for 12V sealed/flooded lead acid or GEL batteries.
- Fast STD Mode: Max 22A charge for 12V sealed/flooded lead acid or GEL batteries.
- Fast AGM Mode: Max 22A charge for 12V AGM type lead acid batteries.
- AGM Recon Mode: For 12V AGM batteries with 22A Max charge current capacity that have been unused for a long time or deeply discharged. This mode reconditions the battery but may decrease battery life, so consultation with the battery vendor is advised.
- Slow Lithium Mode: Max 7A charge for 12V LiFePO4 batteries.
- Fast Lithium Mode: Max 22A charge for 12V LiFePO4 batteries.
- Mode Selection: The mode button is used to select the desired charging mode within 10 seconds of connecting the AC mains.
- LCD Display: Provides real-time information including battery voltage, charging percentage, current, and charge stage. It also displays indicators for full charge, reverse polarity, wrong battery type/charging failure, and auto-recondition.
- Indicator LEDs:
- Power LED (Green): Indicates power connection to the charger.
- Status LED (Green): Solid green indicates the battery is fully charged. Blinking green indicates the battery is charging.
- Status LED (Red): Indicates a charging failure, battery problem, or reverse polarity.
- Special Modes:
- Lithium Activation Mode: For LiFePO4 batteries in Under Voltage Protection Mode where the BMS has disconnected external terminals. This mode provides a constant 13.9V at 22A for 10 minutes to reactivate the BMS. It is activated by holding the Mode button for more than 4 seconds.
- Quiet Night Mode: Reduces output current to 5A and turns off the fan for quieter operation. Activated by holding the Mode button for 4 seconds during charging (after pre-charging period). Charging mode icons will flash when active.
- Connection Options: Can be connected using alligator clamps (via an Anderson connector) or directly to an Anderson connector charge port on a battery box or other device.
- Charge Memory: If AC power is disconnected, the charger remembers previous settings and resumes charging in the same mode once power is restored, provided clamps remain connected.
Maintenance Features:
- Protection Features:
- Polarity Protection: Prevents charging if clamps are connected incorrectly. The RED LED blinks, and charging will not start.
- Short-circuit Protection: Automatically shuts down if clamps are accidentally touched together while powered.
- Over Temperature Protection: Reduces charge current to 2A if internal temperature reaches 95°C to protect both the charger and battery.
- Safety Instructions:
- Designed for indoor use only, away from excessive dust or moisture.
- Do not expose to rain, moisture, sand, or excessive dust.
- Ensure adequate air clearance for cooling fan intake and outlet.
- Do not cover the charger during charging.
- Disconnect 240V AC mains supply before connecting/disconnecting to the battery.
- Do not charge non-rechargeable, frozen, or damaged batteries.
- Do not charge lithium batteries below 0°C (32°F) or without an in-built Battery Management System (BMS).
- Do not charge batteries smaller than 15Ah or larger than 300Ah.
- Ensure good ventilation to dissipate flammable gases from lead-acid batteries.
- Avoid sparks or flames near the battery or engine.
- Do not leave unattended for long periods.
- Ensure vehicle engine, ignition, and accessories are off before charging.
- Connection to mains supply must comply with National wiring rules.
- DIY Repair & Modifications: Opening the charger or attempting modifications/repairs without KickAss consent voids warranty. Damaged AC cords must be replaced/repaired by an authorized professional.
The charger is designed for ease of use with its clear LCD display and indicator LEDs, providing essential information and safety warnings during operation. Its robust protection features ensure safe and reliable charging for a wide range of 12V batteries.
