CTEK MULTI US 3300 12v Battery Charger 56-158

CTEK offers a wide range of NEW GENERATION battery chargers. Unlike old battery chargers, CTEK chargers are designed with a focus on simplicity, safety and flexibility. The MULTI US 3300 is the charger that every household needs. It is perfectly suited for motorcycles, cars, lawn mowers, jet skis and any other vehicle with batteries up to 120Ah. Simply connect it and battery problems are in the past.

Fully automatic – for charging and maintenance

There is no need for any specific knowledge of batteries or their charging methods; the MULTI US 3300 will take care it. Once switched to the preferred mode, the charger takes its own readings and then begins to charge the battery. Once it is finished charging, it will automatically switch to its maintenance phase – CTEK’s patented pulse charging – arguably the most caring mode for a battery connected for a long time. Simply connect it to solve most battery problems from the past.

Flexible for different battery needs

The MULTI US 3300 is specifically developed for different needs, vehicles and batteries. There is a choice between three different modes. The low current mode (the motorcycle icon) is perfect for smaller 12V batteries such as motorbikes, lawn mowers, jet skies, snowmobiles, etc. The higher current mode (the car icon) is for automotive or marine applications with larger batteries. Finally, an additional winter mode (the snowflake) is specifically aimed at charging and maintenance in cold weather. It is also perfectly suited for Optima Red Top batteries.

Patented desulphation function

Unused batteries lose their power and their life is shortened through sulphation. It is also more difficult to charge sulfated batteries. The MULTI US 3300 has a patented method for reconditioning sulfated batteries. The charger analyzes the state of the battery and, if possible, recovers the battery and its power.

Compatible with other electronic equipment

Most vehicles today are equipped with sensitive electronic systems. Unlike less-sophisticated chargers, there is no need to disconnect the battery; the MULTI US 3300 is specially designed to not damage electronic systems.

Made for all weather conditions and situations

The MULTI US 3300 is prepared to charge and maintain, no matter the weather, temperature or situation. The MULTI US 3300 is extremely robust and water and dust resistant (IP65 classification). The MULTI US 3300 is certified for use between -4°F and +122°F. In order to make things easier and more convenient, the Comfort Connect (eyelet terminals) can be permanently connected to the vehicle’s battery.

Designed for safety

All CTEK models are designed to consider the safety of the user. They are spark free, making the connection much easier and safer considering the gases batteries normally produce. The MULTI US 3300 is also protected from reverse-polarity connections and is short-circuit proof. A red light on the charger will simply indicate that the charging cannot begin until the user has connected the charger correctly.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.
**) Ripple describes the quality of 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. High voltage ripple could harm other equipment that is connected to the battery. MULTI US 3300 delivers voltage and current with very low ripple. The battery has a long service life and there is no risk of damage to other electronic devices connected to the battery.

Restocking fees are not profit for us.  They are to cover processing, overhead and manpower.  Restocking fees are not a set-in-stone issue and are dealt with on a case by case situation at the discretion of NEAA.  Customers are responsible for all shipping costs to return an item unless item arrived damaged. Shipping charges are not refundable except in situations where an agreement is made between you and Never Enough Auto.  International Customers: Never Enough Auto does not refund duties or taxes charged by your country for importation of foreign items.  Returns for exchanges or refund will be allowed only within 14 calendar days of the receipt of your product(s).  This will be verified through shipping (tracking number).   Merchandise must be NEW, unused, and in original sellable condition.  Merchandise showing signs of having been installed, modified, mounted, scratched, painted, or defaced will not be allowed. It's the responsibility of the customer/installer to verify the correct fitment and/or vehicle application before installation. For fitment issues, customer must first contact the manufacturer of that product for verification before a return/exchange can be authorized.  Please email us for manufacturer's contact information.  Returns/exchanges must be sent prepaid and insured by the customer.  An issued RMA number does not automatically imply a replacement or refund.  All products will be inspected either by us or the manufacturer based on customer claims before any refunds/exchanges are issued.  Returned items must be sent back to us within 20 calender days from the time the RMA is issued.  If the item returned to Never Enough Auto or one of our manufacturers/distributors is found in violation of the above conditions, it will be the responsibility of the customer to pay for the shipping of the returned item back to the customer should the claim be denied.

Refused Shipments
If a customer refuses a shipment, they will forfeit all shipping charges of the item to them times two.  Once for the shipping to them, and once for the shipping charges we will be billed for the return of the package.  The item will also be handled as a Return and will automatically be subject to a restocking fee per the discretion of NEAA unless other arrangements have been made in advance with NEAA.  Unclaimed shipments and returned shipments due to nondelivery are also subject to these terms.

Part Applications Listings:
Never Enough Auto cannot claim to know everything about every vehicle manufactured, especially when it comes to special edition vehicles and submodels.  NEAA can only go by the information provided to us by the manufacturer of the product.  We strive for the application listings to be as accurate as possible per the information provided by the manufacturer.  However, it is also the responsibility of the customer to be aware of the products they are purchasing and what models they fit (Due Diligence).  Should you have any doubt, or question the applications we have listed please don't hesitate to contact NEAA or the manufacturer for verification of fitment.  Issues that arise from inaccurate or incomplete application descriptions will be dealt with on a per-situation basis at the discretion of NEAA.

Electronic & Engine Internal Components
We will not accept any returns of installed electronic components unless there is a manufacturer defect.  In that case, the customer can send the item back for a replacement of the exact same item.  No refunds will be given in this case, and the customer is responsible for all shipping charges.  Electrical merchandise returns and issues will be handled in Warranty situations only.  Engine Internal components simply cannot be returned under any condition due to their fragile nature - if something miniscule happens to them it can go unnoticed and then blow up someone else's motor - we arent taking that chance.

Damaged Shipments
If a shipped order arrives with obvious damage, customer is to call Never Enough Auto, or the shipper and file a damage claim. The shipper is responsible for reimbursement payment for damaged goods.  Do not install the item!  Do not discard the packaging!  If you do, you may be forfeiting the ability to make a claim.
