The AMT24-12 has many names Trickle Charger, Battery Maintainer, Battery Saver, Reverse Charger, Top Up Charger, Battery Equaliser, but its purpose is to keep a Source / Vehicle Battery charged & protected from damage during prolonged periods of Vehicle, Boat & Motorhome inactivity or storage. The charger feeds a low current into the Source Battery to compensate for self discharge, alarm & tracker loads while ensuring the charge of the Auxiliary / Leisure Battery is maintained.

In the ideal scenario a Solar Charger or Mains Charger is attached to an Auxiliary / Leisure Battery to protect it from damage during a period of inactivity . The Trickle Charger draws a small current off to maintain the Vehicle / Source Battery.

The AMT24-12- is used on systems with a 24V Auxiliary / Leisure battery which is required to maintain a 12V Vehicle / Source battery which has a high parasitic load. The Trickle Charger feeds charge from the Auxiliary Battery to the Vehicle Battery until they reach 11.5V and 23.4V repectively ensuring that both Batteries are kept as healthy as possible even if no Solar Charger or Mains Charger is present. The unit has a low current draw of less than 2mA on a 12V system and so presents a very small discharge load to the Vehicle and Leisure Battery in prolonged storage conditions.
