You would need to put in a regulator that gave you a voltage above six volts to match the battery.
You could instead get two 6V batteries and wire them through a switch that would put them in series for charging and then toggle to putting them in parallel for discharging.

At low current, say a 1 or 2 amp rated charger, this can be done simply by using a 6.3 volt zener blocking diode in series. the wattage rating of the diode is the limiting factor. a 15 watt device with a heat sink would handle 2 amps. the better/simpler solution is a 6 volt charger such as is commonly available for gel cels.
charging up 2 batteries in series will work once or twice, but eventually they will require an equalizing charge which takes special equipment and timers. mountain top microwave relay stations use 48 volt batteries and are equalized about once a month.

Yes, if you have two 6 volt batteries wired in series you can. It has been safely done.
Batteries have multiple cells that are wired in series to get the final voltage anyway so a 6 volt battery has half as many cells as a 12 volt if you are talking about a lead acid battery.
This means if you are wiring two 6 volt batteries in series you really are making a 12 volt battery which will be no problem to charge with a 12 volt charger.

yes, watts = volt x amps
all batteries have like 1.5 amps
you just need either a volts amperes switchy thingy
or
amazing math skills. (its the old 8 hotdogs and 6 hotdog buns problem)

Not safely. You could put a lamp in series between the charger and the battery, and if you are fussy about monitoring the battery voltage to prevent an overcharge, you could get away with it.

Well if you had 2 of them ( the 6V ones) you could put them in Series and then try and chage with a 12V one - assuming the potential applied for charging the 12V should be theoretically twice that of 6V

No! the battery will probably explode

No!
Actually, those sound like someone's famous last words, right before the KA-BOOM!

yes
the Battery will explode

Does the word "explosive" have any meaning to you?
Don't do it!!!
