Ensure all components are in place and working correctly.
All servicing should be performed by qualified service personnel.

Moving and Storage:

Store inside, in a cool, dry place.
Do not store clips on the handle, clipped together, on or around metal, or clipped to cables, as they are live when the switch is ON and can cause arcing. Always place the switch in OFF and keep clips on storage holders when not jump starting.
Take care to prevent damage to cords, clips, and the unit during transport.
Crucially, charge the internal battery immediately after purchase, after every use, and every 30 days.
Keep the battery fully charged. The ideal storage temperature is 70°F (21°C).
The internal battery self-discharges over time, especially in warm environments. Leaving it in a discharged state can cause permanent damage. Regular monthly charging is essential for satisfactory performance and to prevent permanent damage.
Do not store the jump starter in any area where damage could occur if the internal battery unexpectedly leaks acid.
