Because size and weight of SYS-TECH Laptop Battery is limited when compared to larger SYS-TECH batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a , SYS-TECH laptop battery, select the batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:

14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This SYS-TECH Laptop Battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this SYS-TECH Laptop Battery could power your laptop for 2.8 hours.
