Smartech STC3.5 6V/12V 3.5A SLA/LiFePO4 8-Stage Smart Charger & Maintainer suitable for Cars

8-STAGE SMART CHARGING
This is a fully automatic battery charger with 8 charge stages.

All Smartech chargers are equipped with a sophisticated micro processing controller that ensures optimal charge is delivered to the battery whilst protecting the battery from being overcharged.

8-stage charging is an accurate and comprehensive charging process that will result in better battery performance and longer life expectancy when compared to traditional chargers.

Smartech 8-stage smart chargers are suitable for many 6V and 12V battery types including LiFePO4 batteries, Absorbent Glass Mat (AGM) batteries, Colloidal Sealed Lead-Acid (GEL) batteries, Motorcycle, Maintenance Free and Calcium batteries.

The 8 charge stages are:
Diagnosis, Pulse, Soft Start, Bulk Charge, Absorption, Analysis, Equalization and Float.
STAGE 1 – DIAGNOSIS
The Micro Controller Unit (MCU) will analyse the condition of the battery to provide correct charge or prevent the charging of a defective battery.
STAGE 2 – PULSE
If necessary, a Pulse charge is applied to aid in reducing the build up of sulphate crystals on the plates of a discharged lead acid battery. This method is also known as Desulphation. This stage does not apply to Lithium Mode.
STAGE 3 – SOFT START
Start the charging process with a gentle (soft) charge.
STAGE 4 – BULK CHARGE
Constant Current charging until desired voltage is reached.
STAGE 5 – ABSORPTION
Constant Voltage charging. Current will diminish as the MCU maintains a constant voltage until fully charged.
STAGE 6 – ANALYSIS
Charger output will stop, and the charger will analyse the battery to ensure it holds its charge.
STAGE 7 – EQUALIZATION
After analyzing the battery, the charger may start to charge the battery at a higher voltage in order to balance the voltage of each cell. This stage does not apply to Lithium Mode.
STAGE 8 – FLOAT
The MCU will continue to monitor the voltage and apply a maintenance charge as required.

SWITCHMODE TECHNOLOGY
Using the latest technology in battery chargers, switchmode chargers convert 240V AC power to 12V DC power using electronic components unlike traditional battery chargers that rely on heavy transformers. This allows the charger to be lightweight and compact without sacrificing on performance.

SPARKPROOF & POLARITY PROTECTION
Prevents the output leads from sparking due to accidental reverse connection or short circuit, making the charger safer to use around batteries.

SHORT CIRCUIT PROTECTION
The charger provides protection against excessive currents, short circuits and overloads. If such a fault is detected during charging, the charger will automatically terminate the charging program.

OVER VOLTAGE PROTECTION
The charger will provide protection against voltages that exceed the acceptable voltage rating. If such a fault is detected during charging, the charger will automatically terminate the charging program.

OVER TEMPERATURE PROTECTION
If the charger’s internal temperature limit is exceeded, the over temperature protection will be triggered to protect the unit against overheating.

ADJUSTABLE CHARGE VOLTAGE
The charger’s voltage can be selected to suit 6V or 12V batteries.

AUTOMATIC BMS ACTIVATION
Will automatically re-activate a LiFePO4 Battery Management System that has shut down to protect the battery.

LED CHARGE INDICATOR
LED lights will show the charge status (25%, 50%, 75%, 100%) and can indicate a battery fault.
