Activator 282 Aircraft Battery Maintenance Charger
1. Introduction
The Activator 282 is a compact aircraft battery maintenance charger, intended to
be connected to an aircraft battery and left unattended for an extended time. It is
lightweight and compact and connects directly to the aircraft battery terminals.
It uses an IEC60320 power inlet and can operate from any global line/mains AC
power source. No other tools or equipment are required to use the Activator 282.
The unit will charge a 24 Volt lead-acid or nickel-cadmium aircraft battery using
the standard MS3509-compatible connector. DO NOT use it on any other
battery voltage or chemistry, such as lithium ion. The Activator 282 displays the
battery voltage on its Liquid Crystal Display and shows its status with three
lights on the front panel. The unit charges at about 2 to 3 Amperes maximum
current and regulates the battery voltage to prevent overcharge. After the battery
is fully charged, a short “topping” charge is applied to reduce sulfation in lead-
acid batteries and to equalize cells in nickel-cadmium batteries. Then the unit
shuts off all charging and monitors the battery open-circuit voltage. As the
battery self-discharges to a low charge level, the Activator 282 starts another
charge cycle. All operation is completely automatic and requires no user
interaction.
