Battery Issue

Would like to know if anyone has had a problem with a new battery overcharging and emitting a bad smell? Two new batteries installed about a month ago, only one has a problem.
Thank you,

I had one battery explode because the other had a shorted cell and the charger, a three stage, kept pumping the juice to them.

I would recommend you shut down the system, isolate the batteries (disconnect one of them), give them a few hours to stabilize, and then check them thoroughly.

If there is a bad smell the battery is likely being overcharged most likely due to a problem within the battery. I would take it back where you bought it.

Also check that the converter / charger is not overcharging ... hydrogen sulfide gas is given off during charging (rotten egg smell) and is also flammable ... even explosive in confined spaces. It might just be coincidental that the converter has gone bad rather than the old batts being bad ...

Also make sure the converter/charger is the right type for the batteries in question. Using a charger optimized for wet cells is not good for AGM batteries, and vice versa.
I thought getting old would take longer!

Thanks for all the advice and info shared. It was a bad battery and it has been replaced. That was a close one! Will never forget that smell!
