    Carefully disassemble the unit and check the battery number and capacity. You can usually find a replacement through the company that Black & Decker sold out the Vector Division to or even on eBay! I've replaced the batteries for about $20 dollars, but sometimes it's better to wait for a sale and get a newer digital unit and recycle the old one.

They all have the same gray battery in there... but first connect it to the car batery while the car is running for about 30 minutes and see if the battery charges. The little cjharger you have could be not doing a good job...

I have a 350 amp Black & Decker jump starter model JUS350B.Why can i not get power across the clamps with a test light

First: the Jump-Starter power switch must be in the "On" poistion, or no voltage will be delivered to the clamps to light your test light.

Second: from the Black & Decker JUS350B owners manual (,JUS350B.pdf?_ga=1.9223413.1518759147.1438019791)
This product has a sealed lead acid battery. For maximum battery life, we recommend the Jump-Starter be kept
fully charged at all times. Recharge before first use, immediately after each use, and once a month if not used.
Failure to do this may reduce the battery life dramatically. To check the battery charge status at any time, press
the Battery Charge Level Pushbutton.
When the battery is overly discharged and if the green LED is lit when the charger is plugged in, this indicates the
battery is at a high impedance stage.
In this event, recharge the unit and leave the unit on charge for a period of 24-48hrs before using the unit.

Also, the product reviews by consumers about this (made in China) product are abysmal:

Where do I plug in the cord to start charging the jump starter (Black & amp; Sage ) 900 peak ,350

Google for an owner's manual. I can't find anything on this jump starter, but first they need to be charged, usually by plugging into a wall socket for 12-24 hours. Then plug into the cigarette lighter for 10 min or so to give the car battery a boost charge.

You can try to call Interstate Battery 888-772-3600. I have purchased batteries for my jump packs from them before.

Make sure that the switch is turned to the charge position.
Some models you have to do this before you plug it in.
If the battery in the charger is bad you can get a replacement at radio shack.
