Battery Equalization

Yes, 20 hr rating basically gets "converted" to straight amps for this purpose. So, a 150Ah battery should be equalized at a constant 7.5 amps until the SG in each cell stops rising. How fast this gets accomplished depends on the size of the battery bank (larger banks equal slower equalizes) but mine takes 2-3 hours with 10+ amps going in (I don't have any control currently so amps will taper like it does when charging...mine starts somewhere over 12 and will drop to 6 or so). MEX says I need two of those HF's to make it really fast. I could just separate the pairs and do it that way too. For knowing what full is I go by Trojan's guide (mine are Trojan's) of 1.275 at 77F and I do compensate for temp. I figure if the SG rise stops over that I'm good. You get some SG lag anyways so best not to overdo it. Sometimes mine will stop under 1.275 but if I leave them sit with no charging for 8 hrs or so and check again, it will be right at my baseline 1.285 or thereabouts.
