What has Trojan done ?
Just printed the T-145 data sheet from the company website to verify my Magnum charge params and noticed a little change.. From my .pdf published in 2015: Bulk: 13.8 Float: 13.2 Eq: 15.5 And ...

They are finally realizing that wishful-thinking-optimum-always-connected charging protocols are a buzz of the past. Like it or not. Since the days of World War II, lead acid storage battery maintenance has changed very little.
I did hard ball calculating to determine which algorithm would render maximum kWh for least cost generator recharging on my bank. This isn't piddly grade economics because a Kubota 4 cyl turbo uses just a wee bit more fuel than an RV generator or portable. Cost of fuel is the one and only major component in a larger bank. The calculation changes if refueling means running next door. in my case, it is 60 miles and fighting traffic to Lazaro Cardenas, and back.
Six drums around 50 gallons each. $30,000 worth of 2-volt cell batteries. A $16,000 genset. A Lambordini $5,000 385 ampere 28 volt 2nd generator.
Because of .330" positive plates I chose 29 volts instant charging voltage which drops .4 volt during the summer. Three hours of needless feeding a 4 cylinder Kubota costs money. Lucky for me I can piddle-fiddle when power is resumed BUT BUT BUT. We now have demand meters and the kWh tariff TRIPLES in cost beyond 3 Kw.
Feeding 3,250 ampere hours of 28 volt bank is not cheap. Think 27 8-D batteries.
