A: YES you can provided that the current is limited as specified by the manufacturer.. In other words you will need a limiting resistor of the right size.
No.
No, the battery charger has to match the voltage of the battery it is to charge.
Yes. The voltage of charger has to be slightly higher than the battery for it to be able to charge the battery.
Usually a SLA Battery (12 or 24 Volt) with Capacity depending on "up time" after loss of power and if it is an "online" or "offline" UPS. See Wikipedia
No, a 12-volt charger cannot charge a 36-volt battery. The electrical potential difference across the leads of a charger must exceed the electrical potential difference across the terminals of any battery it is expected to charge. And 12 volts is much less than 36 volts.WHY?The 36-volt battery would require at least 39.3 volts to get to a float charge. This would charge the battery to 80% quickly, and then take a logarithmic period of time to finish the battery. To actually charge the 36-volt battery correctly would require roughly 43.2 volts, but if we can't get 39, this is irrelevant.The 12-volt charger has no chance.The answer above is correct; there is no way the 12-volt charger can charge a 36-volt battery. However, the voltages given apply only to lead-acid batteries. They would be different for nickel metal hydride or lithium cells. You still need a charger with more voltage that the battery voltage in any case.

You should charge the battery with the proper battery charger. The battery charger should list what types of batteries, voltages, and charge rates (amps) it is compatible with. Make sure this matches the information on the battery to be charged. Using the incorrect battery charger can cause battery explosion, leaking, or fire.
No.
No
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
Power or energy cannot be measured in volts. The only thing you can say is one - the 9 volt battery - has a higher voltage than the other, the 6 volt battery. If you are asking about the power or energy contained in a battery, then the amount iof energy it can supply depends mostly on its physical size that is determined by the battery "type".
Charge it with a 12 volt battery charger.
No, the battery charger has to match the voltage of the battery it is to charge.
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
no it can't
No it will not work
A 12 volt battery will not hurt you BUT any POWER supply (especially a 230 Volt one) has the potential to harm you.
