No, you cannot.

can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
The battery is a 12V car battery.
No, you can not charge a 3V battery with 12V charger.
Anything needing 12V to operate.
what is meant by "car audio"? an amplifier will not turn on if it is missing either ground, 12v or 12v accessory turn on. the respective wire colors will be large red wire for 12v battery source, large black wire for -12v ground battery or chassis, thin blue wire for accessory 12v turn on. these wires can be tested for 12v with a multi-meter or a simple test light. a car radio is basically the same wire design for power up, most radios will need 12v to the yellow wire, accessory 12v for the red wire and chassis ground for the black. test these wires the same way the amplifier is tested and repair any wires not functioning correctly. if this does not help, respond with more detailed accurate assessments of problem for further advise.
In order to use the "plug in" pest control with a 12V battery, the device would have to have power requirements less than or equal to that which a 12V battery can provide. The pest control would also need an adapter to use the 12V battery.
Yes. I had a 23A, 12V, battery for my ceiling fan and replaced it with an A23, 12V, battery, and it worked just fine.
Voltage is the same but amp hour capacity of the car battery is much higher.
Yes, their 12v mobile battery pack will work with all of their 12v gloves that are otherwise designed to be connected to the motorcycle's battery. The only downside to connecting the glove liners to the mobile 12v battery is that there is no place to store the battery on the glove itself, while all of the Core7 and the Hybrid gloves all have battery pouches in the cuffs.
