Battery Tender Plus 12V /1.25A
June 11, 2022

Deltran Battery Tender Plus is an excellent product, five of them I use on my cars. Ive used them for more than two decades my oldest tender died recently and I replaced it. The factory battery in my oldest car lasted 15 years with a Deltran Tender Plus. The next longest, another car, was 12 years.

Please note, Aircraft Spruce Australia's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce Australia assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

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. Thank you.

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.

Q: Does this Battery Tender charger shut off automatically?

It does not shut off automatically but it does switch to a "float mode" once the battery is at full charge.

Q: is this compatible with 12 v Concord batteries?

No, we have a note on our website saying *DO NOT USE WITH GILL OR CONCORDE AVIATION BATTERIES. SEE DOCUMENTS TAB FOR EXPLANATION.
