WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.

Unit of measurement used to measure the ability of the battery to store electricity or the capacity. The storage capacity is obtained by multiplying the outflowing current in amperes by the discharge time in hours. Ampere hours are abbreviated to Ah.

Example: 

A battery that supplies 3 amperes for 20 hours provides 3 A x 20 h = 60 Ah.
