Charging voltage for T-105s
Continuing my quest to learn everything I can about batteries and charging... Moved on from the group 24 Interstate, may mess with it more later. Also put the hydrometer with the floating balls whe...

Set an Intermatic 12-hour timer with that Shumacher and you create a charger worthy of a brick of gold bullion. But it's not yours unless of course a deal could be struck. Heh heh heh.
14.8 is a great choice for a 5% antimony battery at 20c up to around 25c. But when gen charging time is money and secondly TIME SPENT AT X VOLTAGE is critical. 14.8 IS TOO HIGH OF VOLTAGE if charge amperage is weak and it takes forever and a day to get there.
6-cells of GC220 Can swallow 70-amps and not even burp. Keep it in mind when musing chargers. In order to simplify my life I have a minimim of two chargers going - when down to 1.200 I put a 3rd online.Voltage INSTANTLY goes to 14.80 Then I gain AUTOMATIC reference as to HOW LONG I should maintain 14.8 charge rate. Either through a weak sister cell dip or the minus amp hour reading on the amp hour meter. This is a laughably easy mental computation that you will learn in short order - how mu h time to twist the timer dial.
But a 70-amp charge rate is no laughing matter to obtain. You do not need it for shore power recharging but you do need it for generator recharging if you wish to spend the majority of the day in silence.
The difference in recharging time between 14.4 volts and 14.8 volts is astonishing. Remember I am talking about getting to these voltage value quickly the modulating the time spent at those values.
And obviously this is for generator recharging when boondocking. Solar does not eat gasoline, rattlevand hum and demand oil changes.
Flooded batteries are like a parrot. They hate to be ignored. Both will die early deaths if ignored. A charge maintainer is the best thing for flooded batteries.
I have thrown you a bunch of quandaries here. Some are not so simple to resolve.
