OP originally wrote:12.5V is 80% SOC. According to the Trojan document you provided, the rate of charge drops off from 20% at 80% and quickly drops below 10%. Why do you insist he needs something to provide 20%?
"While in storage, batteries should be boost charged every 90 days or when open circuit voltage drops to 12.5 volts for a 12 volt battery. Boost charge batteries using a constant voltage charger set to 14.4 to 15.0 volts for a 12 volt battery.
14.6V @ 10A meets his needs
