Lifeline says that their AGMs are fully charged when the charge rate drops to 0.05% of the 20hr rate. That is 500ma for a 100AH battery. After that, float charging is optional because the battery is ready for use.
Any meter that reads zero Amps is close enough.
That is all we have to go on with AGMs.

Something isn't quite right with the quoted numbers—if 500 mA (i.e. 0.5 A) is 0.05% of the 20 hr rate, then the 20 hr rate works out to be 1000 A.
You are correct. I meant to say one-half of 1 percent, or 0.5%.
For a 100AH battery, 500ma is correct.
To be more clear. the charge Volts are 14.3 +/- temp comp and the float Volts are 13.3 +/- temp comp. The 500ma is based on charge Volts.
