20 lbs
The battery in my 1995 Ford Explorer weighs 45 pounds
It varies with the size of the battery. They do not all weigh the same.
Different sizes have different weights. Around 30 pounds is average.
It depends on the battery used. Older batteries batteries, like Cadmium, will be relatively heavy, while 9V alkali batteries today weigh about 100g and 9V lithium batteries weigh about a 3rd of that at 33,8g
With any 12 volt battery charger.
Buying a six volt battery is better than 12 volt. If you buy the 6 volt takes up less power so it holds more.
You "could" run a 120V 5A window AC unit off a 12V deep cell battery but, assuming 100% efficiency (something you can never get), you would need an inverter or motor-generator set and 50A out of the battery to run, and maybe 5 or 10 times that to start.
No, a 12 volt 12 amp deep cycle battery will not keep your motorcycle running. A deep cycle battery is one that can survive repeated deep discharge cycles. As the voltage reduces, however, your motorcycle may stop operating correctly, because it is not designed for this type of battery. The proper solution to your problem is to fix the cause of the charging system problem in your bike. Besides, if you check the specifications on the required battery, you will probably discover that it is rated for much more than 12 amps.
That would depend on the size of the battery, you want the amps of the charger to be reasonably proportional to the capacity of the battery.
The wattage of a deep cycle 12-volt battery depends on its amp-hour (Ah) rating. To calculate watts, you can use the formula: Watts = Volts × Amps. For example, a 12-volt deep cycle battery rated at 100 Ah would have a capacity of 1,200 watt-hours (12 volts × 100 amp-hours). However, it's important to note that the actual usable wattage may vary based on the battery's discharge rate and efficiency.
