Product Manual
20
Float – The second and nal Constant Voltage stage in a 3 stage charging algorithm, or the
only Constant Voltage stage in a 2 stage algorithm where the battery is held at safe voltage
indenitely.
Amp-Hour Capacity – The energy capacity of a battery expressed in the number of hours the
battery can last a specic output current. For example, 100 Amp-Hours means that a battery
can supply 100 amps for 1 hour, or 10 amps for 10 hours, etc..
C/20 Rate – The number of amps that a battery can supply for 20 hours. For example a 100
amp hour battery should be able to supply 5 amps continuously for 20 hours. Battery capacity
varies with the discharge rate. The higher the discharge rate, the lower the capacity of the
battery.
Deep Discharge Battery – a battery designed to have a lower maximum current capability, but
can be repeatedly deeply discharged without damaging it or seriously affecting its lifespan.
Engine Starting Battery – a battery designed to produce a very high amperage for engine start-
ing, but typically does not tolerate repeated deep discharging.
