QUESTIONS re: MEGA-WATT 33-AMP POWER SUPPLY
This critter can be found on eBay. It is a switching type power supply. Supposed to have an ultimate amperage potential of 33, voltage adjustment of 10, to 15, and work fine as a long term battery ...

The proof is in the pudding...as they like to say in UK and Canada.
Once tweaked, the only lifespan degradation of a battery would be inevitable plate erosion, and corrosion (electrolyte). Pure kWh + time stasis determine battery life.
A home made system like this can be adjusted to any battery type within the charger's voltage potential. And it is not a disposable item. Once built it lasts for years, with an occasional relay changeout to turnaround degraded contacts.
A freakin' HOME 120vac cyclic timer can be used to power the relay (120vac coil)
Or, with a mere addition of silicon rectifiers, controlled through a timer controlled relay, a single unit can bulk and absorbsion charge to ANY voltage within it's range, then drop .7 volts (silicon rectifier) .4 volts (Shottky) or .7 + .4 = -1.1 volts through a series silicon + shottky diode of adequate capacity.
Example 14.8 bulk/absorbsion YOU set the time at voltage limit then drop 1.1 volt for float 13.7. Is 13.7 too high? Use series silicon rectifiers for a 1.4 volt drop ie 13.5 float.
The HYDROMETER determines what does what, when. Not Fong Lee, scratching his head with a breadboard, and crying in Wu, "Oh oh, cannot do. What hell I do now?"
