Radio Shack has a 6 volt 4.5 amp hour for $15 that weighs 1 lb. I figure about equal to 12 AA's (1900 mAh), and size makes it practical for a headlamp with toolbelt power or overcoat pocket
So, I am now wondering what is the most street-practical way to charge it, and its 3 brothers, for daily work use. I have a 12 volt auto battery charger with 2 amp and 6 amp setting; wondering if put two of these 6 volts in series, connected to the 2 amp setting, and use a 3 hour timer?
Or, I could use the 6 volt 6 amp charger, with a 1 hour cutoff. (something like 1.43 time of rated capacity)?
Is my two charging options above possible with those times? (Do you measure charger voltage not under load?) (Doesn't 1 to 3 hours sound a bit too fast? Is so what resistor would I need at what wattage rating?)
