I bought A Stanley 450 jump start & I'm to charge it for 24hr. The 2 red lights are on but the green light is still blinking after 14hr. What does the blinking light mean?

Good for jumping the car start, may be haardeous to charge the battery.

get it serviced

It's has a bad battery if this us happenings

I would suspect that the internal battery has reached the end of its life. Surely there is a green light to indicate when it is charged?

The smart thing to do is, after using it for a jump start, leave it connected for 5 minutes and it is charged again... otherwise a normal 12 V charger will do on the clamps that go to the box... I use a 12V Stanley 25 amps when needed. But most of the time I keep it connected for 5 minutes and do not worry about it.

Before the first use, the unit must be charged for 24 hours with a connection to an AC outlet (120V). Make sure that all of the switches are off. After that, stop charging when two red and one green LED Battery Status Indicators light.

If you are recharging the unit from a 12V battery, do not charge for more than 6 hours. (Check for a full charge by disconnecting the DC charging adapter and then press the Battery Power Level button.)

The manual for the Stanley J309 battery jump starter is available on the product page here: http://www.baccusglobal.com/stanley/j309.php . The direct link to the manual is http://www.baccusglobal.com/stanley/manuals/JUMPERS/J309%20MANUAL.pdf .

I hope this helps.

Partner , when the red light stops blinking , that means its fully charged
