BATTERY CAPACITY**
* An additional multiplier is included to compensate for the higher discharge rate in alarm.
** Battery capacity decreases with age, a four year old battery can lose up to 50% of its capacity.
Compensations should be made to allow for this loss.
NOTE:
The minimum battery size used should be 6 A.H. and the
maximum battery size is 15 A.H.
