The Schumacher SE-3000 is the ideal charger for heavy-duty fleet and industrial use. The SE-3000 charges a variety of batteries: 6, 12, 18 and 24 volt. With this charger, you no longer need to separately charge 18- and 24-volt batteries. Full power engine start is available in each volt range. This fan-cooled fleet charger provides 200-amp 12V and 150-amp 6/24V engine starts for emergency starting under severe conditions. A single rotary switch addresses all volt ranges for ease of use. And a "Hold" position on the timer switch allows for continuous charging.

Heavy-Duty Transformer for Extra Power and Long Life
The industrial-sized, heavy-duty transformer in the Schumacher SE-3000 brings the power you need for fleet charging applications. An easy-to-read, color-coded amperage meter displays the current charge rate. Choose the amperage you need for your next charge from an easy-to-use rotary switch:

Timer and Hold Position
Chose the 'hold' position for continuous charging or set the timer up to 2.25 hours. To properly set the timer you must know the size of the battery in ampere hours or reserve capacity in minutes and the state of charge.

Rotary Switch
The Schumacher SE-3000 employs a 7-position rotary switch letting you select the out voltages of 6, 12, 18 or 24 volts. Use for charging a battery of the same voltage of charging multiple battery combinations wired in series. Each voltage range offers a high or low amp charge rate. The higher charge rate is more suitable for fast charging a battery to the point where it will start a vehicle, the lower (slower) charge rate is more suitable for fully charging (restoring) a battery.

Integrated Ammeter
The ammeter indicates the amount of current measured in amperes that is being drawn by the battery. For example, In the 50 amp charge rate a typical discharged battery will initially draw approximately 50 amps. As the battery continues to charge, current will taper to 15 to 20 amps at full charge. The Start area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine, the starter motor draws upwards to 200-300 amps. The meter needle will be at the extreme right side of the start area. Sometimes a battery for the first few minutes of it’s charge will draw more than 40/60 amps, in this case the needle may be within but not to the extreme right side of the start area.

Heavy Duty
Designed for rough conditions the SE-3000 is enclosed by a durable powder-coated steel case. Connect to the case are a 6-foot power cord and output cables with heavy-duty clamps, giving you a total of 12 feet of reach.
