Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM

Be EVER so careful interpreting an exercise such as this into real world practicality.
The mere evolution of 1% calcium added to the negative plate (i.e. hybridization)can skew all of the data beyond uselessness.
I do not care for this paper. Complete qualifications need to be prefixed, suffixed and annotated to the text. First up, what is/was the construction methodology of the units under test? Plate thickness? Plate paste? I did not even get so far as to read if the electrolyte was absorbed, or gelled. Some VRB's use liquid electrolyte. What was the density of the electrolyte? Variances per pack after test?
There are innumerable methods to determine inappropriateness of battery maintenance voltage amplitude.
The article mentions early failure of VRB used for standby. It does not mention the sloppiness, variance from design specification found in apparatus chargers.
For crying out loud 99% of the VRB maintenance chargers out there have zero temperature compensation.
There exists a formula expressed in kWh / ampere hours capacity used to determine the amount of energy needed to maintain a lead acid battery. Yes it must be emended for temperature.
