Car Battery Tender: Best New Car Battery Charger Tender

A car battery tender is an essential piece of gear for vehicles that sit for extended periods of time without running.  Classic cars, cars that are stored for the winter, extra vehicles, motorcycles, water sports vehicles, ATVs, RVs, and others all need a car battery tender to charge and maintain their batteries reliably over long periods so that they are ready to go when you are.

Typical car battery tenders produce fairly low voltages because they’re designed primarily for keeping a battery fully charged and secondarily to recharge a depleted battery to a full charge.  The advantage of a higher voltage car battery tender is that it will be able to recharge a battery in less time.

Charger Operating Modes

The charger uses four charging modes to effectively, automatically charge and maintain 6V and 12V batteries:

  • Qualification/Initialization Mode: The Monitor Circuit verifies appropriate battery voltage levels and good electrical continuity between the battery and the charger DC output.
  • Bulk mode (full charge, constant current, battery is 0% to 80% charged)
  • Absorption mode (high constant voltage, battery is 80% to 100% charged).
  • Storage/float maintenance mode (low constant voltage, battery is 100% to 103% charged)

LED Status Indicator Lights

It has several status LED indicator lights that provide simple, easy-to-understand visual confirmation of the chargers operating mode and battery condition:

  • No light: Battery is no properly connected or the charger is not connected to AC power
  • Amber Light Flashing: Battery charger AC power available and the microprocessor is functioning properly
  • Amber Light Continues to Flash: Battery voltage is too low (less than 3 volts) or the alligator clips or ring terminals are not properly connected
  • Steady Amber Light: Battery is connected properly and the charger is charging the battery.  The Amber light will remain illuminated until the charger has completed the charging stage
  • Green Flashing Light: When the green LED flashes and the amber LED is solid, the battery is greater than 805 charged and may be removed from the charger and used if necessary, although it is best if the battery remains connected until the green light is solid
  • Steady Green Light: Charge is complete and the battery is ready for service or can remain connected indefinitely
