I found the CTEK Multi US 3300 12-Volt Smart Battery Charger on Amazon, but it calls it a charger, even though I have seen that several are using this Ctek 3300.

Is this the correct one to maintain the battery charge?
Does it also charge if I should ever have a dead battery?

Thanks,
The Ctek 3300 is an excellent choice, unlike the Battery Tender and other cheaper units, every Ctek has a desulfating step in its charge profile, and all models have a specific charge program for the Optima spiral wound AGM batteries as well. Great units and worth every dime.

All maintainers are just that; they are designed to maintain a battery that is already in a generally good state of charge. They are not for charging dead batteries, they simply lack the amperage for that.
