A battery tender is not the same as a charger.
The tenders put out a low current (like the 0.6 - 0.75 amps mentioned) that is meant to maintain a battery that sits without use and can be kept on for a long time. A charger, like for our size batteries, will put out 2 amps and is meant to charge a low or dead battery and has to be removed when the battery is fully charged. These are not usually expensive enough to have tapering charges and go into a float mode after the batteries are fully charged, and can overcharge and damage a battery if left on for a number of days.
They are two different animals and have different uses.
