Battery Question
I have gone through 4 Superstart batteries the last couple of months. I noticed my cranking and deep cycle were sizzling as I put them on the charger. Noticed one of the batteries were slightly leaking acid and took both of them back to OReilys to tell them what was happening as I was charging the batteries. They plugged them in and said they heard the same thing. Replaced both batteries and I had them test my charger(Ranger Dual Pro) and it was only pushing 2 amps like its suppose to. Get my two new batteries and they're doing the same thing. Exchanged the deep cycle again but this time for a pro series deep cycle battery. I tried plugging them into another charger and slightly heard a sizzle but not as bad. Is it normal to hear a slight sizzle in a battery while charging? Surely I couldn't have bought 5 bad batteries...they've made this noise on two different chargers albeit not as bad as the dual pro. Is my dual pro charger bad now? I can't find an answer from anyone. Any help would be appreciated!

I have never heard a sizzle while charging any batteries.

Yeah that's what a lot have said, but I also have had some that say they hear it too. You have to put your ear to it to hear it. I just can't believe that five different batteries and two different chargers all mysteriously suffer from the same problem. Has nothing to do with my boat because I've tried both charger with just the batteries.

There should be some boiling which I believe results from current passing through the electrolyte. Is the battery hot to the touch? Too much boiling can indicate overcharging a battery.

All I hear are crickets, that's how bad my hearing is. Do the batteries function properly?

You have some pretty sensitive hearing. Yes that sound you are hearing is normal. When battery is discharged and it starts charging, the chemical reaction creates tiny bubbles and heat that sounds similar to grease in a skillet. Hard to hear unless you get ears close to battery which I wouldn't advise doing on a regular basis. That gas coming out of battery is pretty rough on lungs and eyes. I am really curious as to how they determined your chargers amp output.

I believed they put a voltmeter up to it while it's plugged in. I think I'm just not going to worry about it. I really appreciate yalls input. I feel a little better about it after hearing from quite a few it's normal.
