humm...as I'm still playing/learning about things 12volt (charging,
solar, capacities, etc) I wonder if anybody else has come across this....
the hydrometers you buy at auto parts stores must be specific to start batteries or something....on one side the scale reads "recharge, fair, good" and there are actual numbered values on the other side....
as it turns out my batteries are fully charged if the reading is
just slightly into the "good" scale....sort of misleading I thought.... if somebody was just taking a quick reading....he'd think his
battery is only 2/3 charged when it is actually
100% charged....and that is even temperature compensated!!! (see pics)
On another related subject...My trailer no longer has a converter....I have two GC batteries and a charger period....As a Xmas present to myself
I decided to upgrade my simple three stage charger with something better (and with no fan)
Went shopping and came back with this charger that can do just about anything except make coffee!!! probably overkill but the next model down stated that it could recharge batteries up to 120Ah (my bank is over 200) this one, with a few more bells and whistles, says it will recharge batteries up to 230Ah.....not quite sure if I understand why/how this rating difference is arrived at (don't make sense to me) but I decided to go for the higher rated model as it had a few more functions that could come in handy in the future...
so the plan is to install it as a permanent fixture in the trailer (whenever the trailer gets plugged in it will power up).... but in such a way that I can easily take it out of the trailer and use it for something else if need be (it has a plug on the DC side to swap from
battery spring clamps or eye terminals....the eye terminal part will stay with the trailer)
merry xmas
