CTEK Power's Multi US 7002 is a primary switch mode battery charger with pulse maintenance, representing state-of-the-art technology for battery charging. The Multi US 7002 features multiple charging modes, as well as a unique 8-step charging curve. Taken together these refined and new technologies allow the Multi US 7002 to move far beyond the capabilities of other 12V chargers, even to the point of determining whether a battery can hold the charge given, and in the process ensure that each of your lead-acid vehicle batteries gets the best possible care. Eight-step Automatic Battery Charging Cycle Going forward, there is no need for any specific knowledge of batteries or their charging methods; CTEK's Multi US 7002 will take care of that. Once you switched to the preferred mode, the charger takes its own readings and then begins to charge the battery in 8 steps. These include: desulphation, allowing for possible reconditioning of batteries that have lost power due nonuse.; Soft Start, which charges until the battery's terminal voltage has risen to a preset level; Bulk, in which primary charging to approximately 80% occurs; Absorption, a final charging stage where voltage is kept at a preset level; Analysis, during which charging a suspended and voltage measured; Recondition, where the battery is fed a constant current of 1.5A and maximum voltage of 15.7V; Float, during which constant voltage is maintained; and finally Pulse/Maintenance Charging, in which the battery receives a pulse of electricity when the voltage drops below 95%, keeping the battery in perfect condition indefinitely when it is not used. The Multi US 7002 is also perfectly suited for Optima Yellow Top batteries and can also be connected for months, which is ideal for seasonal vehicles. Safe, automatic charging, utilizing three separate modes, suitable for all-weather conditions. View larger. 8-step battery charging explained. View larger. Includes alligator clips with cables for instant connections, and a set of battery cables with eyelet terminals for semi-permanent installation. View larger. Various modes for flexibility in charging. View larger. Multiple Modes for Flexible Use The Multi US 7002 is specifically developed for different needs, vehicles and batteries. With this in mind users can choose between several different modes. These include: Normal, for wet, maintenance-free and most Gel batteries; Cold Weather mode, recommended for use in conditions <41°F; Supply Mode, a maintenance mode supplying a constant voltage of 13.6V; and Recond Mode, a unique mode used to recondition batteries that have been severely discharged. Charging for All-weather Conditions A very light and compact charger, but still extremely robust and water and dust resistant (IP65 classification), the Multi US 7002 is designed to charge and maintain batteries, no matter the weather, temperature or situation. The Multi US 7002 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 and Compatibility 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 7002 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. Key Features: Eight step, automatic switch charging, with patented desulfation functionality to recondition batteries that have lost power due to non use. Charges 12-volt lead-acid batteries (Wet, MF, Gel, AGM and Ca). Maintenance pulse charging increases battery life and gives superb performance. Multiple modes including: Normal, for wet, maintenance-free and most Gel batteries; Cold Weather mode; Supply Mode, a maintenance mode supplying a constant voltage of 13.6V; and Recond Mode, a unique mode used to recondition batteries that have been severely discharged. Low back current drain, low ripple and input voltage independent. Delivered with two interchangeable connection leads, one with clamps, and one with eyelet terminals. The charger can be connected for months, ideal for seasonal vehicles, and compact design with mounting holes allows for permanent assembly. 5 year limited warranty.

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. The Multi US 7002 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.

5.0 out of 5 stars Better than what I expected!, December 8, 2006

This review is from: CTEK Multi US 7002 12V Battery Charger (Automotive)

I first saw CTEK battery chargers featured on Dream Car Garage, and they spoke highly of it. Superior electronics, technology, etc, etc. Being an avid car and boat enthusiast, I also saw ads in some publications and decided to try it out. Right of the box I thought "WOW" is this thing small (about 12"x4"x2"), and less than 3 pounds. I researched CTEK through the homepage and saw that it is approved for Optima batteries which I have for my classic cars and my boat. I used this charger on my trolling motor batteries and took readings before and after use. I fully charged my batteries with my old charger and the batteries read 12.4 and 12.9 volts. I plugged the CTEK charger in and put it in RECON mode and took readings the next morning. The batteries read 14.4 volts and 14.6 volts. The CTEK charger was able to pump in some extra power! I took my boat out, trolled all day, I barely tapped into the 2nd battery. I took my boat out a couple more times with the same results. UNBELIEVABLE! Before I used to pray I was getting back to the launch ramp, and now I'm barely using my second battery! It's made me a believer. Even though it's waterproof, I did't mount it because only single bank. Maybe they will come out with a multi-bank charger. If they do, I will definitely buy that charger too. I am very impressed with this charger. Only downside, the manual doesn't explain charger functions all that well, but it's really not hard to figure out. 5 Stars from me!

5.0 out of 5 stars A step up from ordinary chargers, January 17, 2010

This review is from: CTEK Multi US 7002 12V Battery Charger (Automotive)

I've always owned the typical 15lb car charger. This is quite a step up in technology - smaller and lighter than a quart of milk, and comes with a nice enough carrying pouch for the charger and any accessories you might add. I also bought the cigarette lighter attachment, so I don't even have to open the car's hood/trunk and remove the battery terminal cover to charge the car. This is a good choice to keep an infrequently-driven weekend car (or boat) topped off. I feel much more comfortable keeping one of these connected for battery maintenance than the old-style dumber chargers.

It's not as suitable as one of those old-style boxes for blasting a quick 50amp charge into a completely dead battery to get the car started - the charge rate is an approximately steady 7 amps until the battery is charged. The old style chargers may begin at 10, 20, or even 50 amps, then taper off rapidly below that as the battery begins to take a charge.

One thing about most lead-acid car batteries - you really don't want to let them get completely dead, or they permanently lose some of their ability to take and deliver a charge.

This review is from: CTEK Multi US 7002 12V Battery Charger (Automotive)

I have a little battery charger(50 amp) and a big standup charger(200 amp), and this little fellow has pretty much made them obsolete, at least in my garage. I really love the multiple step charging cycles of this smart charger. I have reconditioned several batteries and they have all came back great.
