After learning two things: 1- Most if not all chargers go into float too early. 2-AGM's need to get back to 100% as much as possible or quite regularly.
Say if my AC charger goes into float at 98.5% SOC (2amps taper current for 130AH AGM for example)
If I leave it on float for another 1hour+ the current tapers down to 0.5%. Is this full 100% charge or not?
Some say you need to taper down to 0.5% at absorption voltage.
Dying to know the answer, cheers
