Batteries measure

Why use heavy duty batteries?
Heavy Duty non-rechargeable batteries, also recognized as carbon zinc or zinc chloride, provide dependable, economic power solutions for every day use. Generally used in low drain, consumer electronics, heavy duty batteries are configured in the most common sizes (AA, AAA, C, D, 9V), as well as, specialty sizes for telecommunications, hobby and industrial uses.
What is an Ampere?
The amount of current flow within a circuit. Measured in Amps.
What is mAh?
mAh (milli-ampere hour) is a capacity rating that measures how much current a battery will discharge over a specified period of time (typically a one hour period). Higher mAh ratings do not necessarily reflect how fast current can be drawn, rather, how long a current can be drawn. For example a 2000 mAh battery will sustain a 2000 milli-Amp (2 ampere) draw for approximately one hour before dropping to a voltage level that is considered discharged. A 1700 mAh battery will sustain a 1700 milli-Amp (1.7 ampere) draw for approximately one hour. Overall capacity will be influenced by other factors including temperature, depth of discharge and speed of discharge.
What is Ah?
Ah (Ampere hour) is a capacity rating that measures how much current a battery will discharge over a specified period of time (generally a 20 hour period). Higher mAh ratings do not necessarily reflect how fast current can be drawn, rather, how long a current can be drawn. For example a 20Ah battery will sustain a 1-amp draw for approximately 20 hours before dropping to a voltage level that is considered discharged. A 40Ah battery will sustain an 8-Amp draw for approximately five hours. Overall capacity will be influenced by other factors including temperature, depth of discharge and speed of charge/discharge.
What is Cut off voltage?
Recognized as the voltage at the end of a useful discharge. Cut off voltage will vary by device. However, the cut off voltage for a device specifies the inoperable point for the device utilizing battery power.
