battery choice
Hi, I am in analysis paralysis. I will be purchasing AGM jars. Here are my two choices: AGM L-16 Surrette 400 amp-hour six volt with 0.145 plates cost $520 plus tax and shipping Four are n...

Notice the specs say "charging (constant voltage)" max 80a initial current.
Does this refer to bulk or abs charging?
Also, note that these are rated at 400Ah. How many multi-stage charger manufacturers/marketeers talk about bulk charging ending at around 80% soc?
It just so happens the remaining 20% of those 400Ah's is 80a... So, 80a tapering in abs/cv mode.
If the 1a:-1Ah ratio is acceptable at 80% soc, why would it not be acceptable at a much lower % soc, when charging efficiency is greater, and charging voltages and battery temps are lower?
As for temp compensating, it remains the same... simply find a suitable Vabs to maintain that 1a:-1Ah ratio, and adjust accordingly from there.
