How long will a 12V 18Ah battery last?
You can draw 0.9 Amps from an 18Ah battery with 12 volts for 20 hours.
What does 12V 18Ah battery mean?
An 18 A battery is one which is rated to produce 18 amps of current at rated voltage, which is not something all batteries can do. An 18 Ah battery can produce a current which, when multiplied by the time (in hours) the battery can supply it, equals 18.
How many watts is 18Ah battery?
On the face of it, a 12V, 18Ah battery is a 216 Watt hour battery. (BUT, over most of its discharge curve, a ’12 volt’ battery will be providing a voltage greater than 12, so the real figure is somewhat above the straight 12×18 calculated figure.)

What does 70ah mean on a battery?
For example, an average automotive battery might have a capacity of about 70 amp-hours, specified at a current of 3.5 amps. This means that the amount of time this battery could continuously supply current of 3.5 amps to a load would be 20 hours (70 amp-hours / 3.5 amps).
How long will a 12v battery last without charging?

Which is better lead-acid or gel battery?
Gel batteries score highly with their low electrode wear, which results in a longer service life in comparison with conventional lead-acid batteries. However, due to their increased internal resistance gel batteries cannot produce high cold start currents within short intervals.
