hi,
If i have a 12V 10Ah lead acid battery,what does 10Ah stands for...
Does it mean an average of 10Amps of current supplied for an hour, or the time taken for a full 10Amps supplied.
If i have a dc electric motor(12V 10A) would this battery go well with it?

You have it basically right.
But the confusion lies in how the companies test their batteries.
Unless otherwise specifically noted lead-acid batteries are tested at a 20 hour rate. That means yours can deliver ½ Amp for 20 hrs.
Higher currents will give a lower AH capacity. I would estimate at 10 Amps your motor may run 20 to 30 minutes.
The way to precisely check is to look at the discharge graphs for your model of battery. Look on the manufacturers web site.
If you don't have luck, email me your battery model and Co. at ocdwizard@hotmail.com, I may be able to track down some info.
Best of luck. Charley
BTW what are you making?

10AH is 10 amp-hours. In theory the battery will supply 10 amps for 1 hour. It is less stressful to the battery to supply 1 amp for 10 hours.

For the 12V 10A motor, you should use a battery with a higher AH rating than 10. I would probably use a 30 AH battery.

In theory 12v at 10 ah would run your motor for one hour at full load. However in reality as the battery discharges the voltage drops and the current flow would rise ( as watts remain the same)but the output of the motor would also decline. If however you would want to use a 12v 1 amp motor. you would get pretty good service for the first nine hours.

10Amp hours is either 1amp for 10 hours or 10amps for 1 hour. I would not use that motor unless you plan for using no more than one hour and charging the battery right away. Why don't you buy a marine deep cycle battery. You can pick up an 80Amp hour deep cycle for about $60.00 at an auto place and those are designed for recharging after going completely dead. Good luck.

the battery delivers 12 v at a rating of 10 amp hours which means it can push a 12v 10 amp current for one hour. so this battery should run you motor at load for one hour

You're right. Ten amps for one hour or 1 amp for 10 hours. You would be able to run your motor for one hour.

It doesn't answer your question, but .....

unpop5's "However in reality as the battery discharges the voltage drops and the current flow would rise" is not true.

The current would also drop.
