How long will a Battery of 7.4 Volts 700 Amp-Hour last?
The voltage doesn't enter into the issue.If the current draw of your battery-powered equipment is 1 Ampere, the battery will last 700 years.If your equipment draws 1/2 Ampere, the battery will last 1,400 hours.If your equipment draws 2 Amperes, the battery will last 350 hours.And so on.CorrectionA 700 AH battery will THEORETICALLY last 70 hours at 1 amp current draw. A 700 AH battery will THEORETICALLY last 140 hours at 1/2 amp current draw.A 700 AH battery will THEORETICALLY last 35 hours at 1/2 amp current draw.The theoretical capacity of a battery is always greater than the actual capacity; electrical energy is released in the form of heat inside the battery.

Battery changed several times and alternator checked however 1988 Olds Regency 98 still drains battery What would cause such a drain on a daily basis?
It's going to be a long process but what you got to do: Pull ALL the fuses. Now check to see if there is still a draw on the battery. There shouldn't be. Replace one fuse at a time. Each time, check for draw on the battery. Save the radio for last. The clock and memory are a constant draw (a very small one). To check for draw, go get a cheap ammeter at some auto store. Wire it in according to directions, near the battery where you can see it.
