I just installed two brand new Trojan T-105's in series. I noticed when i was charging
them at work
to equalize their voltage there was a slight odor
of rotten egg. I didnt pay much attention because they are brand new. it odor
was not very strong just slightly noticeable when i put my nose over the battery
. it seemed to dissapear after charging
for a little while.
Now today i installed them in the boat
. i hooked everything up and had the charger
on for a few minutes so i could set the charge and float voltages. I noticed the smell in the battery
compartment from the few minutes they were charging. i turned off the charger
and its gone away now.
I have a brand new charger (Sterling Pro Charge Ultra) and set the charge voltage at 14.8 and float at 13.5 according to Trojans data sheet for the T-105's.
were fully charged already when i turned on the charger. water
levels look good. the charger has a temperature sensor which i do have connected and is working. during the charging process, at work
initially, and just now, the batteries
feel cool to the touch. there is absolutely no area where the batteries get even slightly warm.
so why am i getting the hydrogen sulfide smell? from everything i read about it, its not something to be taken lightly but everything in my setup is brand new, including all the wiring
etc...i didnt leave the charger on to see if it would go away because the batteries are already fully charged.
is it possible it happened because they were already full when i turned on the charger and they just got slightly over charged? is a slight amount of smell normal for these batteries when the charger is first turned on? Is it possible i have bad batteries? The Trojan company is close by to me and the distributor should be carrying pretty fresh batteries.
