What this charger does
The BatteryJack inc. 12V Battery Charger Maintainer 3.8A Goldwing is a smart charger and maintainer for lead-acid batteries including SLA, AGM, GEL and VRLA types. It suits capacities from 2 to 90Ah and works with both 6V and 12V systems. An LCD display shows status while automatic protections handle reverse connection, over-charge, short-circuit, over-temperature and high or low voltage conditions.
Check your battery and supply first
Confirm the battery is a lead-acid type within the 2 to 90Ah range and rated for 6V or 12V operation. The charger requires a 12V 60Hz AC input, so verify your mains supply matches. Choose the correct detachable lead set — alligator clips or ring terminals — and select the appropriate mode for motorcycle, car or snowmobile use before connecting.
What the bundled leads and modes change
Detachable and interchangeable lead sets with pole clamps and ring terminals let you switch between temporary and permanent connections without tools. The mode selector tailors the charge profile for motorcycle, car or snowmobile batteries, while the LCD indicator reports progress so the unit can be left to operate automatically.

Questions about this item
What comes in the box and what must be purchased separately?
The charger ships with detachable, interchangeable lead sets that include both alligator clips and ring terminals, so no extra cables are needed for standard 6 V or 12 V lead-acid batteries.
How do I decide between the 6 V and 12 V output settings?
Choose 6 V only for 6 V batteries; for every 12 V motorcycle, car or snowmobile battery — including the Gold Wing — select the 12 V setting, which delivers up to 3.8 A and a peak voltage of 14.4 or 14.7 V.
What does the 3.8 A maximum charging current mean when the unit is connected to a typical motorcycle battery?
It will supply up to 3.8 A during the bulk phase, then automatically taper to a float charge once the battery reaches full voltage, making it suitable for capacities from 2 Ah up to 90 Ah.
