A standard IEC-320 “computer type” of AC line cord plugs into a receptacle on
the Activator 282 and into a wall receptacle. AC line input is 1-- ~ 240 Volts 50 /
60 /400 Hz and can be used worldwide.
2.0 CHARGING
a.) The maximum steady-state charge current of the Activator 282 is 5
amperes with average charge of 3 amperes.
b.) The Activator 282 will charge either Lead Acid or Nickel Cadmium
batteries, and although very compact will bring a fully discharged high
Ampere-Hour rated battery up to full charge including a topping/equalizing
charge. Lower A-H rated batteries are brought up to full charge more
quickly than larger batteries.
2.1 CHARGING TIME
The average time to fully charge and top a completely discharged large (40-50
Amp-Hour) Sealed Lead Acid Battery is approximately 20 hours. Larger or
smaller batteries are charged in proportionate time. Nickel Cadmium batteries
take approximately 20% longer than SLABS to charge, and it is usual to fully
discharge a NiCad before recharge. However, most batteries placed on charge
have some residual charge and average charge times have proven to be about 9
hours for large SLAB batteries, and 5 hours for small batteries. Because of this
relatively slow charge, maximum ampere-hours of discharge are attained by the
battery when in use or test. The Activator 282 will not overcharge any battery,
even if the battery has a high residual charge.
2.2 PULSE CHARGE
If the battery voltage is below approximately 10 Volts, the Activator 282 will
pulse-charge with a series of high current pulses of approximately 10 amperes, 1
millisecond in duration, at a repetition of about 2 pulses per second. This
