**Q: How Long are the cords?**
A: Terminal cord is 6 ft, electric cord is 6 ft (total length 12 ft)

**Q: What is the input AC voltage? auto volt or 120v only**
A: The AC Input is 120v.

**Q: Would this be decent to charge an Exide 24 Dual Purpose Marine Battery? Right now my battery tender waterproof 800 0.75 amp takes quite a while.**
A: This is not a charger in the conventional sense. These (and your Battery Tender) are made to MAINTAIN a charge. If your battery is dead/low you need a regular battery charger to fully charge it, then use this to maintain your charge. Your Battery Tender is only providing less than 1 amp in charge, that's why it takes forever. Like trying to fill a lake with a garden hose!
