Schumacher SPI 16 PRO User Manual

INSTRUCTION MANUAL
Model: SPI 16 PRO
The new SPI Pro series of electronic battery chargers has been designed to charge all kinds of lead-
acid, traditional or latest generation batteries and LiFePO4 lithium batteries. These chargers are
particularly suitable for daily use and for long-lasting maintenance charges.
All charging parameters are set using the charging function keys on the control panel. Depending on
the model, you can set:
- battery type (std: wet or gel, AGM: efb, start & stop or spiral, lithium: LiFePO4)
- charging current according to battery capacity
- the charging voltage according to the battery voltage
- the duty cycle to be carried out: slow, medium and fast charge; deep recovery charge, show
room function and power supply as a replacement to the battery.
Battery state diagnosis stage A1
The charger state of charge of the battery to be charged.
Charging phase:
"Recovery from deep discharge”
The charger starts using a pulse current until the battery has reached
optimal voltage and current levels to start the second charging phase.
Charging phase: " soft I”
Reduced constant current charge
Charging phase : " I”
Charge at constant current until the maximum battery voltage is reached.
Charging phase : " U0”
Charge at stabilized voltage until the current reaches minimum values.
Charging phase : " Recovery” *
Only with charger set on RECON: constant current deep charge phase and
increasing voltage to increase battery charging capacity.
Diagnosis of battery status: "A2”
The charger analyzes the state of efficiency of the charged battery.
Charging phase: " U”
The battery charge status is maintained at a reduced constant voltage.
Charging phase: " Up”
The battery charge is maintained with pulses of current (provided
constantly).
 * RECOVERY function (RECON): this charging mode allows you to recover wet 12volt batteries
that have been inactive for a long time and have acid stratification. This function acts physically
on the electrolytic solution of the battery so that it mixes again counteracting the stratification.
 SHOW ROOM function: the chargers are equipped with the show room function. This function
allows for operation of all the vehicel utilities during demonstrations in the dealership. (Only in
12V mode)
 SUPPLY function: the chargers are equipped with the supply function (power supply). This
function allows you to keep the memory of a vehicle active during battery changes or in all cases
where the battery is disconnected from the vehicle circuit. (Only in 12V mode)
 For battery analysis and error reporting the chargers have been designed to analyze the battery
status before and during charging and report any anomalies in connection between the charger
and the battery to be charged. Through the digital display an error code is displayed, so as to
quickly and easily verify the anomaly that has occurred.
