# How To Calculate Amp Hours Of A Battery Bank?

**Amp-hours** = **watt-hours** / 12 **volts** = 1470 / 12 = 122.5 **amp-hours** (at 12 **volts**). By dividing the **amp-hours** by the **battery** **voltage**, the **amp-hours** will alter if you use a different **voltage** **battery**.

Similarly, How do I calculate amp hours?

The amount of **amps** (A) a **battery** **delivers is multiplied** by the **discharge duration** in hours to get amp-hours (h). A **battery** that generates 10 **amps** of electricity for 10 hours is referred to as a 10 **amps** 10 hours = 100 Ah **battery**.

Also, it is asked, How do you calculate amp hours on a 24v battery bank?

**watt-hour** / 12 **volts** = 1470 / 12 = 122.5 **amp-hour** (at 12 **volts**). By dividing the **amp-hour voltage** by the **voltage** of the battery you’re using, the **amp-hour voltage** changes.

Secondly, How do you calculate battery hours?

Total load (W) / **battery voltage Equals** load current (Amps-Hour) (volts). The total load P(W) divided by the **battery voltage** V(V) in volts equals the load current I(Ah) in Amps hours. The **total loads divided** by the battery voltages times the battery capacity equals the battery life.

Also, How long will a 100 amp hour battery last?

**Reserve The capacity** of 12V 100Ah **general-purpose lead-acid batteries** is normally about 170-190 minutes, while **premium lead-acid batteries** are usually between 190-220 minutes.

People also ask, How do you convert amp hours to watt-hours?

The **equation** is (Ah)*(V) = (Wh). For **instance**, a 2 Ah **battery rated** at 5 V has a power of 2Ah * 5V = 10Wh.
