I am fully aware of you problem you are describing dselec, the batteries are in very regular use (often charged and discharged heavily several times a day) and are often under high current. Disassembling the pack every time just would not be practical.
In the past I have considered some kind of...
I do suspect that when it is putting out 1.5amps for a few hours it would get quite warm (understatement). I will find out once I get the proper connector onto it.
I did originally consider opening the thing up in the hope that I could adjust the voltages using a preset resistor and maybe add a...
I had a look:

The 12Ah are happy with up to 3amps and the 7AH are happy with up to 1.75amps.
Thank you for the fast reply. The batteries are currently in battery packs and I can not recall their exact types however if it is important I can open them up and take a peek. One pack contains 3 12v 12Ah in series the other contains 3 12v 7Ah in series. If my terminology is correct that is...
Hello
I need a charger to charge 3 lead acid (AGM) batteries in series. I finally settled on this one through lack of choice despite it not having the connector I needed (it is simple enough to change). **broken link removed**
I measured its output voltages and it seems to be a bit higher than...
Hello everyone from around the world. I have been meaning to join this forum for some time and have been slowly getting into electronics as a hobby and out of fascination of how things work.
My first topic will be about how I have hit a problem with desulfating some AGM (sealed lead acid...
