Troubleshooting - Schumacher INSTANT POWER XJS4 Owner's Manual

All batteries are affected by temperature. The ideal storage temperature is at 70° F. The
internal battery will gradually self-discharge (lose power) over time, especially in warm
environments. Leaving the battery in a discharged state may result in permanent battery
damage. To ensure satisfactory performance and avoid permanent damage, charge the
internal battery every month.
