They make a 7.5 volt battery when put together
Yes as long as they are both 12 volt batteries.
You don't because of the voltage differences between sources to jump start you must have the same voltage at destination and source the source may be higher than the destination but destination cannot be higher than the source. You could how ever put two 12 volt batteries in series and then use that set to jump your 24 volt system.There are two possible waysIN ANY CASE DO NOT USE ONE 12 VOLT SOURCE TO BOOST BOTH BATTERIES IN THE 24 VOLT SYSTEM AT THE SAME TIME SPARKS WILL FLY AND DAMAGE WILL HAPPEN.The first is to boost one of the batteries for a 10 to 15 minute period then boost the second for the same. if the machine does not start boost the first battery for 15 to 20 min then boost the second for the same period. etc etcThe second way is to have 2 separate 12 volt sources.You can use two vehicles. Each vehicle boosts one 12 volt battery. Connect the positive of vehicle 1 to the positive of battery 1 in the 24 volt system. Connect the negative of battery 1 in the 24 volt system to the frame of vehicle 1. Then connect the positive of battery 2 in the 24 volt system to to the positive of the vehicle 2. The last connection is from the negative of battery 2 in the 24 volt system to the frame of the vehicle 2.do not let the vehicles touch!!Or if you have access to 120 volts use a small battery charger connected to one 12 volt battery and a vehicle to the other 12 volt battery .IN ANY CASE DO NOT USE ONE 12 VOLT SOURCE TO BOOST BOTH BATTERIES IN THE 24 VOLT SYSTEM AT THE SAME TIME.
A 15 amp 125 volt outlet is a household outlet.
No, you need to supply the correct 18V to your speakers.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
None.
Five times 15 equals 75.

No. At 125 volts, the same 15 amp current results in 10 times as much power. Ohm's Law states that amps x volts = power.
Five sixths of 18 would equal 15.
The Dell lithium Ion batteries have a slightly longer shelf life and last 10-15% longer than normal batteries.
