CHARGE IMMEDIATELY AFTER PURCHASE
KEEP FULLY CHARGED
Charge the jump starter internal battery immediately after purchase, after every use
and every 30 days.
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.
