Help my education: why is it especially important for AGMs to be charged at 14.4? 4 hours at 14.4 was mentioned above, but my Trojan T-105 AGM manual says to limit 14.4 absorption voltage to 2 hours. It does say to use a constant absorption voltage of 14.4.
Thanks.
First they say to keep it at 14.4 until amps taper to 0.5a /100AH of battery capacity. Then they say to limit the 14.4 to two hours? How do they know how long it will take to get to 0.5a ???
Also, the T-105 AGM is still a 6v batt, so it takes two to make 12v and that is about 220AH or whatever the AGM version is instead of the Wet's 225. (I forget the AGM number) so it will take a while to get to 1.0a for the 220ish AH. More than two hours!!!
IMO forget that, and go for the proper 0.5a/100AH and never mind how long it takes.
