Brad, First of all in order to charge a battery the source must be HIGHER voltage to make current flow into (charging) instead of out of (discharging) it. Normally, the genny is just a bit higher voltage then the battery, maybe on a 12 volter 13 to 14.5 volts or so depending on its type n quality n rating n the Voltage Regulator etc. Soooooo what happens if you try n charge a 6 volt batery with a 12 volt charger ??? THE ANSWER DEPENDS if its only a real cheap light wimpy low current charger it may (depends on its overload protection n lots other things) well still charge it fine (Ive done it no prob), PROVIDED you donT leave it on too long or overcharge and the lower current n wimpier it is less the chance. HOWEVER if its one of those bigger heavier high current booster type chargers YOU CAN RUIN THE BATTERY cuz too much current may cause excessive outgassing n acid boil over maybe even damage the plates. An overcharge is in a way WORSE then an undercharge cuz it can totally ruin the battery n make it go flat n not take a charge, has to with the lead n adic n lead sulphate n other chemical stufffffff.

Soooooooo depending on the charger and whether or not its a modern so called Smart Charger and its amp and overload rating but MOST IMPORTANT its amps capacity if youre careful n dotn leave it on too long you can charge a 6 using a 12 volt charger buttttttttt dont try with a high amp dumb charger at high charge rates it may (depends on lot of things) blow up or warp the plates or ruin the battery DONT TRY THIS AT HOME LOL

Basically to charge a storage battery you simply pump electrons INTO it versus it forcing electrons out into a load which depletes n discharges it. It converts chemical energy into electrical energy up to a limit
