Review: As advertised great
Review: I have 3 different models from this manufacture. If the battery can be saved, this will do it and do it quick. The Optimate 7 is worth the extra cost. Had to charge my tractor battery and it fixed it in a couple of hours versus the Optimate 6 taking over night. Time is money, this unit is worth the money.

## Questions & Answers

**Q: Approx how long does it take to charge a dead flat car battery with this charger?**
A: Depending on the type of battery, capacity, level of discharge & sulfation, the full cycle may span 2-36 hours.  The full cycle includes cell recovery, charging, cell balancing, and a follow-up test cycle.  In practice, I've personally seen a range of 12-18 hours average for a discharged car battery, depending on the battery's amp/hour capacity.
