Half Awake
Newbie level 4
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 batteries) that were given to me for free. I was given a few Yuasa 12v 7aH (**broken link removed**) They were previously used in some kind of backup system. I wish to use and charge them in series but to do so I need ones that match in capacity (they all from the same batch but different conditions). Currently they are all over the place, some in almost perfect condition others almost unusable. I tested their capacity by putting a 150w load and measure the voltage after 6 minutes. Anyway, my home made desulfator has been very successful in many cases but with these ones they seem to do a bit then hit a wall. An example is 2 that I have which have each been connected to the desulfator for about 6 weeks but only showed improvements for the first 2 weeks.
I am wondering if anyone else has hit this problem with desulfating AGMs
An article I read recently made me wonder if they have dried out, if so it would be worth a try at filling them with water? I know it is not how they are designed but it may be worth a try.
Any input would be welcome.
Thank you
