this battery tender is used for my riding mower, it's keeping battery fully charged and have had no problems except for having to extend lead wires.
The instruction manual should be more detailed as to the nature of Charging batteries - it is not obvious to all and everyone. That would avoid disappointments with the performance of the product
I too tried to verify the voltage output on the unit and got nothing from a voltmeter. I was concerned after leaving this charger on a battery for several months to find the battery was dead when I went to start the four wheeler. I tried to verify the voltage while hooked up to the battery and then after disconnected. I got zero voltage while un-hooked and it read ~6 Volts while hooked up. But her
Tested this with a digital meter -- no voltage & no amperage readings in bright sun. Batterymart referred me to Battery Tender for repair / replacement, but I haven't gotten a response from them in a week.
Perfect way to take care of batteries in cars or motorcycles that are not ever day drivers.
Works well. Size of panel takes up a lot of space but I guess having a large panel is good for getting more sun.
