Charging
Overview
The B22 Extended Power Pack uses AGM batteries that are rated at 24 Volts DC. A full charge may show
over 26 volts, and the normal operating range for welding is between 24 and 27 volts. For optimal
welding, you may need to recharge the batteries when they reach 24 volts or connect the welder to
external batteries for additional welding time.
120 Volt AC Charger
The B22 Extended Power Pack does not include its own charger, but instead uses the 120 Volt AC
charger that was included with your Badger Welder. If you would like an additional charger, or your
charger is lost or damaged, a replacement can be found at
www.badgerwelder.com
or at most battery
supply stores or even pharmacies and retailers that sell electric wheelchairs and scooters. Make sure
the charger is a Fully Automatic Smart Charger designed for 24 Volt AGM batteries and utilizes a 3-pin
XLR connector.
The XLR Charging Port is located on the outside front of the case, to the right of handle. To charge,
simply plug in the 24 Volt DC Smart Charger and follow the Charger manufacturer’s instructions included
with the Charger. When charging is complete, unplug the Charger from the Power Pack. Charging time
will vary based on battery level, but typically takes between 3 and 4 hours. The charging circuit is
protected by a pop-up circuit breaker located on the control panel.
12 Volt DC In-Vehicle Charging
The B22 Extended Power Pack can also be recharged from a 12 Volt DC vehicle. To do this, plug the
supplied 120 Volt AC Smart Charger into the vehicle’s 400w 120 Volt AC outlet if available, or simply use
a portable 400w DC to AC inverter available at
www.badgerwelder.com
or at most auto supply stores, or
other stores that sell vehicle accessories.
Be sure that the vehicle is running to prevent draining of the vehicle battery. Plug the 400w inverter
into the vehicle’s cigarette plug, then plug the supplied AC charger into the inverter and follow the
instructions above for the 120 Volt AC charger. In-vehicle charging times will be similar to using the 120
AC charger alone.
USB and USB-C Charging Ports
The B22 Extended Power Pack includes a dual Charging Port with one USB and one USB-C port. A fully
charged Power Pack can deliver over 100,000mAh
of charge to your portable devices. To use these
ports, press the Power Button located on the USB Port. The USB ports will light up to indicate they are
on. When you are done charging your devices, press the power button to shut off the USB ports to
avoid a very slow drain of the batteries. Be aware that use of the USB ports can drain the batteries
below the voltage needed for welding and could extend the recharging time.
