Can you use a 12 volt charger to charge 6 volt batteries in recessive situation?

That really depends on how the charger is made. What would likely happen is that the charger would try to deliver more current than it is designed to. The result would be either a blown fuse or diodes in the charger unless it has protection circuits in it.
One thing you could try would be a current limit in series with the charger output. A headlamp in series could work to limit the current to somewhere around 3-6 amps and prevent having an overcurrent situation on the charger. Dad calls the light bulb current limit a "rubber fuse" It will take longer to charge that way and you really need to check the battery voltage often making sure not to exceed about 6.75V Be aware that with this method there is no way for the charger to sense that the battery is fully charged. It will continue to try to push to around 14 volts which will never happen until you cause an open cell in the 6v battery.
charger + to headlamp bulb, other side of bulb to battery+ B- to charger-
That could get you out of a pinch but you really need a charger designed for 6v charging.

Can 3 tripleA batteries charge an Iphone safely?
An IPhone, or any rechargeable device, for that matter, should only be charged with the specific charger that was designed for it. This minimizes the risk of overcharging the batteries and damaging them.
Can you charge batteries with a different mAh rating?
You can charge batteries with a different mAh rating if the charger is designed to handle them. You need to make sure of this, because Ni-Cad battery full charge state is not necessarily voltage dependent, but rather is dependent on detection of a change in voltage slope. If the power supply is not properly designed, you can overcharge the batteries, damaging them.
Can you charge a 8.4 volt battery with a 7.2 volt charger?
It sounds like you have nickel-cadmium batteries, since 7.2 volts is an integral multiple of 1.2 volts. You should notcharge a nickel-cadmium battery with any charger that is not specifically designed for it. The issue is that overcharging these batteries will damage them, and that the battery voltage alone is not enough to determine state of charge. (You have to measure the slope of the voltage, and detect the inflection point which occurs at full charge. This is a very specific thing, so the battery must be matched to the charger.)
Can a 0.9V 400MA solar panel be used to charge 2 AA batteries?
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
Can you use a 9.6 volt charger to charge a 7.2 volt battery pack?
Check the internet to see if your charger will automatically step down to 7.2V (not likely if the charger is not the same brand as the battery). If it does not step down then it is possible but *** not recommended ***. Overvolting can cause nasty caustic leaking of toxic chemicals from the battery.
How can you charge batteries?
With a battery charger or alternator.
How do you charge a camera that has no place for a charger?
You can't.. buy rechargable batteries, and a charger. *edited* and if the batteries in the camera (that came with it) are rech... you can buy a charger for those specific batteries.
Can you charge 48v batteries with a 36v output charger?
No.
Is it a good idea to charge different brands of rechargeable batteries in a Rayovac smart charger?
It is not advisable to charge different brands of rechargeable batteries in a Rayovac Smart charger.
Can you charge 4 x 1.2 batteries with a charger made to charge 4 x 1.5 batteries?
where did you get a battery charger that charges 1.5v cells. non rechargeable batteries are 1.5 volts. rechargeable batteries are 1.2 volts. i would throw that thing away and get a new charger.
How do you charge a camera with no charger or batteries?
I am sorry, but I think that this is impossible. It must have batteries to function.
Does the Quick Charge II Instant Cell Phone Charger need batteries?
Yes that the Quick Charge II Instant Cell Phone Charger needs 2 AA batteries.
Can a 9.6 remote control car charger charge a 7.6 battery?
No, you will ruin your batteries and charger.

Can Nimh batteries can be charged with Nicd charger?
It is always better to use a charger designed to charge a particular battery type. Using a NiCad charger for NiMh batteries or vice versa can cause damage to the charger or batteries, especially if the charger is designed to charge the batteries in under two hours. The worst case is a fire risk. Some charger and battery combinations will work perfectly well together but it is safe to assume that the charger will only be suitable for the battery types stated on it.
