better to jump a small battery with a big one. The other way (trying to jump BIG battery with a small one) may result in smaller battery being too weak to do the job or damage to the small battery. The scenario as you have described it is OK.
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
About 11,000
1.5 Amperes, or Amps.
To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
To determine how many amps a battery can handle, this information should be on the battery itself. You can also get a battery tester to determine amperage.
Depends on the battery. They are not all the same. It depends on the battery , a BCI group size 65 battery is rated at 650 cold cranking amps
modern cars use a 12 volt battery. Amps depends on the battery. Common sizes range from 500-800 cold cranking amps.
It varies by manufacturer and battery.
The spec for ignition off draw (all components off, key removed) is .035 amps or less. It can take 5 minutes for the computers to "time out" and go to "sleep".
How many peak amps does it use.
Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
About 650 cc amps
