Batteries Sizzle Like Alka-Seltzer
Should batteries make a sound like alka-seltzer while they are charging?

Yes... it is gas venting.

Yes, at least during the bulk charging phase... they should be bubbling... as the charging process will produce some hydrogen as a by product.

I had an issue a while back that fits in here as a FYI (For Your Information).
My carbon monoxide detector was occasionally going off. Couldn't figure out why. No engine running - pulled the propane tank off the boat as a propane leak can set it off - changed the detector - it still kept going off occasionally.
What I found was the batteries were gasing excessively. Discovered this when the batteries wouldn't last overnight and I replaced them.
So, they should bubble - gas - but there is a limit as to how much they should gas.
I bring this up in case someone else might have a problem with the carbon monoxide detector and can't find anything. Check the batteries.

Good point Essman...they should only bubble during bulk charging.
