venting batteries during equalize

My house bank is 6V golf cart type batteries, do the caps need to be removed during an equalize charge?

My start battery is a maintenance free type battery where you can not take the caps off, is it OK to equalize it.

I've run the equalization before with the caps on and with the start battery in the circuit, but the question never occurred to me at the time.

Re: venting batteries during equalize

I always remove them caps when I equalize, easy to check fluid level and to refill with caps off.

Never equalize a sealed battery. If you leave the caps off a regular battery when equalizing the bubbling will cause a slight spray. So I recommend topping batteries off first putting the caps back on.

Re: venting batteries during equalize

Before you eaualize, fully charge.

You should check fluid levels before you equalize anyway.

Don't equalize a sealed battery.

No need to keep the caps off.

You NEED to be there for all four hours.

Open the hatches.

Watch the voltage, amperage and if you have a bm use it.

Great time to piddle around doing other things.

Equalization is covered pretty well in most "How to take care of your batteries" texts.
