Is it possible to fix or revive a car jump box starter? Answered

I have 2 dead one's at home and can't find anywhere on the web that describe how they work...

Car jump boxes (batteries with attached boost cables) are simply that - a lead acid battery inside of a plastic housing. Take them apart carefully, remove the battery, and take to a battery shop to have it tested. If the battery is 'good' your box is probably bunk. If the battery is bad, get it replaced.
