    In addition, the CTEK MULTI US 7000 is recommended for Optima® Yellow Top batteries.

    Product Features and Benefits

  • Seven step, fully automatic switch mode model.
  • Charges lead-acid batteries (Wet, MF, Gel and AGM) from 14Ah to 225Ah.
  • Maintenance pulse charging increases battery life and gives superb performance.
  • Supply mode for float maintenance for 100 % state of charge.
  • Charges even drained batteries.
  • Pulse recover of slightly sulphated batteries.
  • Four options: 14.4V, 14.7V, 13.6V/Supply and 16V/Boost.
  • Low back current drain, low ripple and input voltage independent (85-125V).
  • High efficiency: 85%
  • Delivered with two interchangeable connection leads, one with clamps, and one with eyelet terminals.
  • The charger can by connected for months, ideal for seasonal vehicles.
  • Compact design with mounting holes for permanent assembly.

    Features for Safer Use

  • Electronic safe, the charger will not damage vehicle electronics. The battery does not normally need to be disconnected from the vehicle when charging.
  • Minimal gas build-up and a patent-pending spark protection system.(however, in supply mode the spark free feature is disconnected).
  • Short circuit and reverse polarity protected.
  • Double insulation.
  • Splash and dust proof.
  • Progressive temperature protection.

    Temperature Protection

  • To protect the charger from overheating, the MULTI US 7000 is fitted with power limitation. The power reduces when the ambient temperature increases. The power also reduces if the charger were to be covered, which protects the charger from damage. The charger continues to work, but at a lower output. When the ambient temperature drops, the power automatically increases again.

    Mounting

  • The charger is easily fitted in place using two screws.

    Ideal Uses:

  • All CTEK MULTI US 3300 applications, plus larger boats, RVs and trucks.

    *)Back current drain is what drains the battery if the charger is connected without the power cord connected.

    **) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery. The MULTI US 7000 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.

2 Year Warranty

Worlds Smartest Battery Charger
By 50thVetteVerified Purchaser from Hollywood, FL on 1/3/2008
Pros:
Clear Instructions, Long Life, Powerful, Safe
Best Uses:
Home Garage, Professional Mechanics
Bottom Line:
Yes, I would recommend this to a friend

If you want the best, this is it. You will need to understand the type of battery (lead acid, gel, AGM) you will be charging in order to choose the optimum charging mode. If you need a smaller more basic unit with similar features, go with the US3300 model for half the cost. The DC wire leads are about 30" in length and if you plan on storing the vehicle for periods of time, the charger has to be either in the engine compartment or right next to the vehicle in order to reach the battery.
