Battery charging

Thanks. I'll do it anyway. I'm only doing it a few times/year.

and, unlike some, you do not seem to be fixated on sticking to manufacturers' charging profiles

Not quite sure what you mean, but anyway I'm assuming that my battery monitors are correct here and the voltage on the bench power supply is its output voltage?

 

 

 

Edit: I have to set the bench power supply above 16v to get the readings on my battery monitors to rise towards that figure.

Ah, you have obviously not been following the DC to DC charger topic.

I read a bit of it. Not every post.

It's up at 16v on the monitors now. I can hear the batteries bubbling but there's no acid on the battery tops and none in the box so I'm just holding it on 16v for half an hour.

I topped up my Trojans today and charged them back up. I was thinking of doing an equalization charge but is now a good time to do it - after topping them up?

 

I think I last did an equalisation charge about 3 months ago.

 

Best to top up before any equalisation charge.

 

Batteries can gas out a surprising amount of electrolyte during an equalisation charge.

Should the batteries be topped-up again once the equalisation charge has been completed?

If necessary, yes.
