Recharging and Calibration Times
Different battery packs will require differing recharge times. The times given below are for a full charge from
0% to 100% state of charge. They are valid for all variants and custom hybrids of each battery model. (For
example the NJ1020HP has the same recharge time as the NJ1020.

Recalibration Time
Recalibration consists of a calibration charge, followed by a calibration discharge. Finally the battery is given
a regular charge. A calibration cycle will be faster if the battery is fully charged to begin with. Recalibration
time is governed by the battery voltage and capacity. Larger batteries, and lower voltage batteries will take
longer to recalibrate. Calibration is initiated each time the button is pressed, so it is not recommended to
press the recalibration button part way through the recalibration cycle.
What are the SMBus and the SBS?
The Smart Battery System denes the parameters that are stored by an SBS-compliant battery. These
parameters include full battery status and fuel gauging information. The System Management Bus is the lan-
guage by which these parameters are communicated between the battery, the charger and the host device.
How does the charger know what to deliver?
The charger is capable of sensing and delivering an appropriate charge to all Inspired Energy NiMH and
Li Ion standard battery packs. Upon inserting the battery into the charger, the battery communicates to the
charger over the SMBus telling the charger what type of cell chemistry it is and what type of charge regime
it needs. The then congures its output to provide the charge regime requested by the battery. If no SMBus
communications are issued from the battery, the charger interrogates the thermistor/resistor I.D. pin on the
battery terminal and delivers an appropriate charge.
Above: the BAT-CHARGER-1 includes an AC/DC
adapter and AC power cable that connects to USA
power receptacles. Customers in Europe / UK can
order compatible power cables with their BAT-
CHARGER-1. Please consult DEWETRON about
your requirements.
