look out!!!
I've been using these things for years but I can't say I've done what I did before.
I keep my bikes and mowers on the regular old metal-cased Deltran Battery Tenders. All the batteries are AGM.
This strange thing happened to one connected to one of my mowers, but it could have just as easily happened to one of my bikes.
I had to move the mowers, so I unplugged the BTs from the wall and set each on their respective mowers. I left the alligator clamps attached to the batteries. Moved the mowers (didn't start the engines, just pushed them) and things sat there for a few minutes.
Then I needed to move one of the mowers again, and in the process, the alligator clip on the positive terminal made a huge pop, major spark and some smoke. I quickly released both the positive and the ground clips and the positive clip had a good-size chuck burned away from its teeth.
Never seen anything like this happen before. On my bike I use the SAE connectors that are wired directly to the battery. When I ride, I unplug the BT and separate the SAE connector. For starting and using the mowers, I remove the alligator clips and unplug the BT.
Did this happen because I left the thing connected to the battery while it was unplugged?
I am a bit shy to reconnect it, wondering if anyone has expertise?
