Default Charger voltage

I got a "on board" charger. I just got the cart converted to 48V. I plugged in the charger and left it over night. When I came out in the morning, the batteries were warm and I could hear bubbling. I tested the pack with the voltmeter and got 56 volts! I know the batteries charge up more than 48, but 56 sounds high. Should I be worried?

Edit, to clarify, the pack measured with the charger still on.

My old 48V charger would hit 58 volts. I think that peak voltage of 56 is ok.

58v is perfectly normal. On trojan & its clones, they are fine until they get into the 60+v territory. 56v is still not quite done yet.

I don't know if that was peak since it was still charging. The batteries are old (all most shot) So that may be a factor. I don't know what the amp rate is on this charger, but I think none of the "on board" chargers are very high.

Thanks for the response. At least it gives me an idea.

The old ferroresonant transformer chargers shut off at about 2.5VPC (Volts per Cell), which is 60.0V for a 48V battery pack, and modern chargers that use dV/dT (change in Voltage over change in Time) technology to determine when the batteries are fully charged, may climb a bit higher than that.

Attached is a recommended charge profile for Trojan batteries and the max voltage is 2.79VPC, which is 66.96V for a 48V pack (24 x 2V cells).

If your charge is working right, it should reach anywhere from about about 59 to about 66V before it shuts off.

I just swapped in some good batteries and started the charger. So I will see what it does now.

Well it charged up the pack and then shut off. It has some LEDs on it that show you what's happening. It has about 5 different charge rates and then a green light that I assume means it is fully charged. There's no real printing on it saying that, but it worked its way up the scale and back down and then the green. When I measured it with the green, it was about 52V.
