Default Some Help

I was just wondering about mah. So if you have a 5000mah battery, and you discharge it continuously at 5 amps for one hour, will the battery reach it's nominal voltage
I have experimented with 3 different 2s 5000mah batteries and the answer is... generally yes, BUT I can only convey this with the following considerations.

1. My voltage cutoff is 3.2v/cell.

2. When I CHARGE my 5000mah batteries at 5 amps AND the battery actually takes a full charge the charge time is darn close to 1 hour. The charged amount is darn close to 5000mahl. At about 50 minutes the current slows and by about 1hr 10min the balance is about finished. Sometimes I allow the balance to complete and this may take 90 minutes.

I apologize for not providing a really good answer based on science. Hopefully this helps.

Sincerely,
