Yes. Both should be in good condition and well maintained. If one goes bad it can drain the other. <><><> Absolutely not if one is weak the healthy one will try to charge or equalize to the same voltage which can cause severe damage to both. The two batteries should not be connected in parallel when they are being charged, they should each be charged separately. <><><> It is important not to overload the battery charger by trying to draw more current from it than it was designed to handle. If you overload it on the side which was designed to supply charging current to just one battery, if it is a very cheap model it may not blow a fuse or trip a breaker on the high voltage side: the current may not be broken and the charger may catch on fire when the internal insulation on its transformer windings breaks down due to a serious overheat condition! So always check the total amps drawn by a battery when it is connected to the charger and be sure to remove it immediately if - because of the battery's poor condition - that current exceeds the charger's rated charging amperage. That rating (output current in amps) should be shown on its Rating Plate. you cannot overload any battery charger even with a short because they are always current limited by design.
It is not recommended to charge a 12 volt battery with an 18 volt charger as it can potentially damage the battery. Using a charger with a higher voltage can overcharge the battery and decrease its lifespan or cause it to overheat. It is best to use a charger that matches the voltage of the battery being charged.
yes
There is a serious risk of overheating/ damage and explosion from the excess voltage. You might get away with this if you watch the battery closely and do not let it overcharge or get too hot. But, my advice is not to do this. Get yourself a 12 volt charger.
Yes. Connect the negative clamp from one charger to the positive clamp of the other, then the remaining clamps to the battery terminals.

Can you charge a 6 volt battery with a 12 volt battery charger on slow 2amp charge?
It is not recommended to charge a 6 volt battery with a 12 volt battery charger as it can damage the battery. The higher voltage can overcharge the battery and cause it to overheat. It is important to use the correct charger with the matching voltage to prevent damage to the battery.
Can you use a 12 volt charger to charge 14.4 volt battery?
It is not recommended to use a 12 volt charger to charge a 14.4 volt battery as the charger may not provide enough voltage to fully charge the battery. Using the correct voltage charger will ensure efficient and safe charging of the battery.
Can you charge a 28 volt Gill aircraft battery with a 12 volt car charger?
No, you cannot charge a 28 volt aircraft battery with a 12 volt car charger. The charger voltage needs to match the battery voltage for safe and effective charging. Using a charger with a lower voltage can damage the battery and pose safety risks.
Can a 12-volt solar battery charger charge a 36-volt battery?
No, a 12-volt solar battery charger is not capable of charging a 36-volt battery directly. The voltage output of the charger needs to match the voltage requirements of the battery for efficient and safe charging. It is recommended to use a charger that is specifically designed for a 36-volt battery.
Can you use a 3.5 amp charger to charge a 12 volt battery?
Yes, you can use a 3.5 amp charger to charge a 12-volt battery. However, charging time may be longer compared to using a higher amp charger. It is important to ensure that the charger is compatible with the battery type to avoid damage.
How you charged the 12 volt battery?
Charge it with a 12 volt battery charger.
