That will depend on the sum of the load resistance and the internal resistance of the battery (this is true for all power sources, not just 6 volt batteries).
Small compact batteries tend to have higher internal resistance and therefore are more limited in the current they can deliver to a given load than larger batteries.
A fully charged 12 volt battery will output 12.6 volts are read with a digital volt meter.
They make a 7.5 volt battery when put together
you put a volt meter on it
Yes, you can use a twelve volt car battery charger. Be sure to set it on low.
No. Unless you put it in a sock and hit someone with it.
Nothing as long as it was a 12 volt battery.
if you put steel wool at the tip of a 9 volt battery
As long as it is a 12 volt battery that fits, you can put as large of a CCA battery as you want to buy.
when you lick a 9 voltage battery you get a tiny shock on your toung and it hurts.
If you put two 12 V batteries in series you get 24 V. Connect the positive of battery 1 to the negative of battery 2. Then you have 24 V between negative of battery 1 and positive of battery 2.
Have the output of your alternator checked,it should put out 14.5 volt. Also check the battery connection to virify that they are clean.
Most 24 volt systems use 2 or 4 12 volt batteries. Be careful not to let the cables get mixed up. They need to be put back in the same spot. Disconnect the battery, Charge each battery individually, Reconnect the cables exactly like they were before. You are ready for work.
