Inverter question
After putting in a set of new 6v batteries hooked in series my inverter started to hum or buzz. Anyone have an idea what would cause this? Batteries were hooked up exactly like the old set. Thank you

- It could be the new batteries need to be brought up to full charge and the charging circuit of your inverter/converter is working harder than normal to do that. Do you know what the voltage of the battery bank is when no charge is being applied? Above 12.6 indicates a full charge and 12.1 is 50% discharged.
- Hooking up 6VDC batteries just like before sometimes doesn't work. You need to find the + and - markings on the battery case and wire those up the same as before... Sometimes the newer batteries have the terminals in different locations even with the same brand of batteries...
Roy Ken - First we need to know what device it is.
- I could see it working harder with lower charge. Not sure what setup you have. But I had to change what size batteries I had in charger/inverter program.
- Most inverters do hum or buzz somewhat. It's the 60 Hz power they are making (or using) that causes this.
Did it not hum before? - I am thinking you mean converter. Your inverter inverts 12 volt power to 120 for use when you are not plugged in. Your converter takes the power from the plugged in wire, and inside the converter is a battery charger. If it is humming or buzzing, perhaps it is charging your new batteries.
Your converter also powers up all the 12 volt appliances, and it can hum while it is doing that too.
