Tpoppa Posted June 20, 2017 Report Share Posted June 20, 2017 So battery on my VFR was completely dead. My fault. I put it on my battery tender and it was making a high pitched humming sound. It didn't appear to be taking a charge at first, but after a few hours it started charging (and the noise stopped). I let it charge overnight and now it seems fine. Anyone ever hear a battery making noise like that when on a charger? Link to comment Share on other sites More sharing options...
Tonik Posted June 20, 2017 Report Share Posted June 20, 2017 I would bet it was just gassing like they often do when charging and the gas was passing over a hole just right to make that noise. Like blowing across the top of a beer bottle, or my dick. Hit it with a volt meter and start it, make sure it doesn't drop too low as it starts. If it doesn't you should be good.

Tpoppa Posted June 20, 2017 Author Report Share Posted June 20, 2017 It wasn't hissing or boiling, I've heard overcharged batteries do that before. It was definitely an electrical hum and just when it was connected to battery tender. It seems OK now Link to comment Share on other sites More sharing options...

It was probably just internal resistance until it was able to accept some juice. Looks like you dodged a bullet. BT's sometimes won't charge a dead battery.

Usually you can't hear it, sometimes you can. Link to comment Share on other sites More sharing options...

It seems fine now, but it is a 7 year old battery. Link to comment Share on other sites More sharing options...
