Stock can vary by distributor, and the chargers are usually sold through battery specialty retailers, industrial suppliers, and authorized ODYSSEY channels.

Setup Guide for the odyssey OSC-70A, OSC-105A Shop Charger

Before setup, confirm that the charger is intended for 12-volt flooded or AGM lead-acid batteries and not for gel or lithium batteries. Place the unit in a dry, ventilated area with enough clearance for airflow, then inspect the AC cord, clamps, and housing for damage. Connect the charger only to a grounded 120-volt AC outlet with the correct circuit rating, and do not use an adapter.

For basic operation, attach the output leads to the battery or vehicle according to the service application, making sure the positive and negative connections are correct. If the charger includes selectable or programmable options, choose the battery profile that matches the battery type and capacity. The 70-amp and 105-amp models support a dashboard interface that displays charging status, which is useful for monitoring charge progress and confirming operating mode.

If the charger does not begin charging, recheck polarity, AC power, and battery contact points. For safety, never connect the charger to a frozen, damaged, or leaking battery, and avoid sparks near the battery. Keep the work area ventilated because charging can release gases. If the charger appears unresponsive, disconnect power, verify all cable connections, then restart the setup from the beginning.

Troubleshooting the odyssey OSC-70A, OSC-105A Shop Charger

Common issues with the odyssey OSC-70A, OSC-105A Shop Charger usually involve incorrect connections, insufficient AC supply, or an incompatible battery type. If the charger will not start, check that the outlet is live, the plug is fully seated, and the battery clamps are clean and secure. If charging is unusually slow, verify that the battery is an ODYSSEY-compatible AGM or flooded lead-acid battery and that the charger output matches the battery’s capacity.

Although the manuals emphasize status display and connection checks rather than a long list of error codes, a no-charge or fault indication commonly points to reverse polarity, poor clamp contact, or a battery that is deeply discharged or damaged. Fixes usually include correcting the clamp orientation, cleaning terminals, allowing the battery to stabilize, or trying another approved battery. Preventive measures include storing the charger properly, using the correct battery profile, and inspecting cables before every job.

ODYSSEY shop chargers carry a 3-year warranty, and technical support is available through EnerSys at 1-800-964-2837. The ODYSSEY literature also lists 1-800-ENERSYS (1-800-363-7797) for service-center routing. If you need warranty assistance, keep the model number, serial number, and proof of purchase ready before calling.
