**Amp hour**is the rating used to tell consumers how much amperage a battery can provide for exactly one**hour**- In small batteries such as those used in personal vaporizers, or standard AA sized batteries, the
**amp hour**rating is usually given in milli-**amp hours**, or (mAh) - For large batteries, the rating is abbreviated as Ah.

**Amp hours explained**and what drains a car battery- The power and longevity of a battery is noted by its
**Amp Hour**(Ah) rating - Basically, this denotes how long a battery will put out an
**amp**of power if it isn’t recharged - For example if a battery is rated as, say 50Ah, it will be able to provide 50 amps for 1
