Battery Tender

Re: Battery Tender

A battery tender is not meant to charge quickly, it only has a trickle charge to maintain battery capacity. Two amps is definitely not near as much as the cigarette lighter socket can handle. Both of the lighter sockets in our birds are "always on". I wouldn't have any reservations about using this type of battery tender. I am an electrical engineer.

I have never needed to worry about keeping the battery charged since my car is a daily driver.

For whatever this is worth, when the Battery Tender came out with an improved charger, now labeled as the "Battery Tender Plus" the charging amps were increased to 2.5 because the sealed batteries they are using in almost everything nowadays, required a little bit more 'horsepower'. I live in Deland, FL, where the main office of Battery Tenders is located, (Actually know as the Deltona Transformer Company) and this information came directly from them.............this is why they are called "DEL-TRAN". That's my story and I'm sticking to it!

Re: Battery Tender

I use a battery tender junior all the the time. With only 2,500 miles the car battery would drain in between use.

I run the cord from above the car down to the upper right hand corner of the trunk lid and attach it to the the other end of the cord which is attached to the battery.

Close the trunk lid gently and there is enough room for the cord to move back and forth smoothly.

I leave a note on the floor that reminds me to unplug before backing out.

The lighter circuits in most cars are fused at 20 Amps or more. The circuit capacity is the same regardless of whether the current is coming in or going out. A battery tender that is rated at 2.5 Amps or less is like a drop in a bucket. It is well within safe limits of the wiring.
