Q: Why can't you use these Battery Tenders with the Gill aviation batteries?
We have added the warning letter explaining the reasoning for this to our "Documents" tab of this webpage. Please review it for the full explanation.
Q: Can I safely use this Battery Tender Plus 12V with an Odyssey 12 volt battery? Can I leave it connected to the battery all winter in the hangar 24/7?
Per the instructions, this can be installed and left as a maintenance free charger, and maintainer for a lead acid battery. Odyssey batteries are lead acid batteries.
Q: Is the Battery Tender Plus 12v compatible with earthX batteries?
Per the Earth X website: It can be used for charging only. Maintenance voltage is too low.
Q: Can this unit or another Battery Tender product be used to maintain my eBike battery? Manufacturer Wu Xi Dpower Electronics Bo Model DPLC275V55.
We do not have any application chart which references your battery. This is designed to maintain small 12v batteries so if your battery has alligator clip access this should work.
Q: What does it mean when the red light is blinking on the Battery Tender Plus?
The red light flashing indicates that the battery charger has AC power available and that the microprocessor is functioning properly. If the red light continues to flash, then either the battery voltage is too low (less than 3 volts) or the output alligator clips or ring terminals are not connected correctly.
