CTEKMulti US 7002, 12V Battery Charger for Cars, SUVs and Trucks, All Weather Smart Charger, Battery Tender Charger, Battery Desulfator, Battery Maintainer, Power Supply Mode and Reconditioning Mode

I did a lot of research before settling on this brand and model CTEK Multi US 7002 Charger. I don't regret choosing it one bit. This is replacing an old Deltran Battery Tender. After inspecting it, I could tell that a lot of thought was put into it's design and functionality. I have it connected to my 2010 Corvette Grand Sport. It was easy to hook up and activate. The main cord wasn't long enough so I ordered the extension cable at the same time as the charger. I ended up ordering the cigarette lighter adapter later. By using the cig. adapter, I can more easily connect and disconnect the charger to the car without opening the hood. By the cable being routed under the door and into the car, to the center console, instead of going into the engine compartment, the cable is also protected better. I like the power supply feature but haven't used it yet. It's nice to know it's there if I need it. I mounted the unit on the garage wall using the two supplied screw holes. I still wish CTEK made a holder for it but I can fabricate one later. It's quiet and the status indicator lights quickly and easily show you what's going on. I like ordering from Amazon and fortunately Amazon had this charger and the accessories at the best price with fast shipping. Now I see why CTEK Chargers have such a great reputation.

I bought this as it was recommended in many car forums. Many recommended the Ctek 4.3 while others the 7002. From my research the 7002 gives you some additional amps (7 amps vs 4.3 for the other unit). I wanted the best so got this one.It saved a 5 year old battery that was on an OEM tender that went dead and thus the battery drained to zero and held there for weeks. I had to boost the battery with another charger to just get some voltage in it so the Ctek would recognize it was actually hooked up to something and then start to do its magic.After about a day the old tired battery was working again and starting the car fine. I ended up taking the car to the dealer and putting a new battery in as five years old is more than you can ask from a Lead Acid battery and going another season was rolling the dice. Their battery tester showed it was still good but on the edge.I used the Ctek Comfort Indicator Eyelet to hookup to the battery. This has LED indicator lights which is a nice extra feature when the charger is not hooked up to let you know the condition of your battery. Amazon sells it and it is not expensive.The unit is easy to use. Just a few settings/options but I just used the standard "Normal" and it is set it and forget it.My last tender was an older Ctek unit that put out only 800mah. It was sold as OEM with the car. When I found out it was 450 bucks to replace the old, cheaper, not as good OEM tender I did my research and found out the OEM was also a Ctek but marked up HUGE. Most of the high line and exotics all use Ctek chargers. So for the price of this charger on amazon I got the best tender/charger unit, a new battery and install of everything for LESS than just the tender would cost me from the dealer with the company logo on it!

I have two cars. One car has a traditional battery and the other has a new style AGM battery. I had an ancient battery charger (10amp) and tried to recharge the traditional battery. Apparently, I left the charger on too long because the sides of the battery started to bulge. I ruined the battery. I went to AutoZone to have the battery tested, and yes, they confirmed that the battery was bad. I bought a new battery.I searched on Google for the best car battery chargers for 2019 and discovered a list of five. They considered the CTEK 7002 as the best. What sold me was a video with Jay Leno (the former talk show host who has lots of cars). He said that all the expensive cars (Mercedes Benz, Porche, Ferrarri, Lamborgini, BMW, etc.) recommended the CTEK products.That sold me. It will charge both the AGM and normal batteries. All you have to do is to select which battery type you are charging and connect the cables. It does take a long time to charge. On my AGM battery, the CTEK took about an hour. The CTEK 7002 goes through several steps of analysis and charging. But, it will never overcharge! You can walk away and come back at your convience.My normal battery (the one that I had just bought from AutoZone) took two hours. Apparently, even though it was brand new, it was only charged up to 80%. The CTEK brought it up to 100%. Again, all I had to do was to select Normal battery and connect the cables to the battery. Then, I walked away to do other things.Oh, on newer cars, if you remove a battery, apparently, you loose memorized settings for your car. The CTEK has a setting where it provides 13volts to your car's electrical system while you remove a bad battery and replace it. This way you do not loose all your memorized settings.This is a very good product. I am a believer.
