Description
The CTEK MULTI US 3300 is a versatile battery charger in a compact format that makes it convenient and easy to charge and maintain all household vehicles. The special cold mode means that you can charge during the extreme winter months without problem. It is perfect for everyday vehicles as wells as vintage vehicles, RV's, boats, motorcycles, ATV's, lawnmowers and tractors. This charger specifically developed for different needs, vehicles and batteries.
It is a fully automatic (connect and forget) 4 step charger. Once switched to the preferred mode, the charger takes its own readings and then begins to charge the battery. Once the battery is charged, it will automatically switch to its maintenance phase. The patented pulse charging process is arguably the most caring mode for a battery connected for a long time.
Unused batteries lose their power and their life is shortened through sulphation. It is more difficult to charge sulfated batteries. The 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.
All CTEK chargers are designed to consider the safety of the user. They are spark free, making the connection much easier and safer. They are also protected from reverse polarity connections and short circuit proof protecting the sensitive electronic systems in vehicles today. If the battery is connected backwards the charger will show a red light and not charge until it is properly connected to the battery.
The Multi US 3300 battery charger has a 5 year Limited warranty

Description
The Battery Buddy Charger / Maintainer is the smartest little trickle charger around. It knows your battery has needs. Battery Buddy gets that and delivers the goods. Its built-in battery brain controls a precise 4-step power program (initialization, bulk charge, absorption, and float modes). Just connect the charger and come back when you're ready to use the battery. While you're away the Battery Buddy will be carefully calibrating its output to your battery, maintaining a full charge without overcharging the battery. If your battery slips below a full charge, Battery Buddy resumes a normal charging cycle. Battery Buddy works for batteries in cars, boats, ATVs, UTVs, PWCs, RVs, motorcycles and any other vehicle in long-term off-season storage in extreme heat or cold. Battery Buddy is uniquely designed to weather the extremes of off-season storage and take care of your battery. Intelligently designed for safe, effective charging of any size battery from big bus to small scooter. Battery Buddy features a waterproof design with a single LED status indicator light that draws almost no current, spark proof connectors, 8-foot output cord, short circuit and reverse polarity protection.
1-year warranty.
*Note: If you try to charge a dead battery having a voltage below 3 Volts, the Battery Buddy will not start to charge because an internal safety circuit prevents the battery charger from generating any DC output voltage at that level. If a 12 Volt lead-acid battery has an output voltage of less than 9 Volts at rest when it is neither being charged nor supplying electrical current to an external load, there is a good chance that the battery is defective.
