This 24-Volt battery charger connects directly to an aircraft / military battery.  Float and auto shut-off modes can be set for Lead Acid or Nicad batteries. The A-282 is a direct connect, fully automatic 2 Amp charger capable of charging a 24 volt military or aviation battery of any rating from zero to full capacity. It is also a standby maintenance unit without the use of “trickle” charging, thus extending the life and durability of the battery. There is no gassing, heat or other detrimental results of trickle or float charge. The digital voltmeter continuously displays battery voltage during charge and standby.
