How often should I charge my jump starter? (models CJS 50, CJI 150, CJIC 250, CJIC 350, CJIC 550)

To maintain a full charge on your jump starter, it is recommended to charge it once per month.

If you keep the jump starter in your home, leave the charger plugged in all the time.  The internal charging circuit will maintain a full charge on the battery without any risk of overcharging.
