My first charger arrived and did not work. I returned the charger (at Amazon’s expense) and the second charger was sent “next day” via UPS. The CTEK 3300 is an extremely easy charger to use. It is small in size which is a plus. It is also less expense than the more well known charger brand. I gave 4 stars instead of 5 simply because the first charger did not work.

I primarily use this charger to keep the battery on my motorcycle charged up when sitting dormant for weeks at a time. The unit comes with two sets of leads that can plug into the unit. The leads consist of traditional alligator clips and eyelets. I have the eyelet leads permanently bolted to my battery with the plug accessible without having to remove the battery. The unit also comes with a nice storage pouch with a nice sleeve to keep the instructions in. The product is very streamline and easy to use. The price is very reasonable compared to other products (which are unusually big and bulky). I’m extremely satisfied with this product and highly recommend it.

This product performs with no fuss and it appears to cycle (as it claims) to recharge a battery while reducing sulfation in an older battery. I have two deep cyle/starting batteries. One is older and one is nearly new. The charger went through many, many cycles to charge the old battery. The new battery was charged within hours. Since then I just switch the connections every few days to keep both batteries ready to go. The instructions are well written and the charger and cables seem to be of high quality. I must say I have only had this product for a few months so I can’t say much about how long it will last, but it appears to be a high quality product.

Wanted to be able to charge the battery in my “Garage Queen” Porsche 911. Did some research and learned that the Porsche Battery Minder that sells for $115 (or more) is made by CTEK and is the same charger as this CTEK Multi US 3300 for around half the price. Only thing I’d like to mention is it does NOT come with the cigarette lighter plug-in but you can get that accessory for around $10 also at Amazon. Once I had both pieces (charger and cigarette lighter plug-in) my battery indicator went from needs to be charged to fully charged in a few hours. Recommended. An email to CTEK was never answered but that’s not Amazon’s fault.

I ordered 2 different chargers to maintain my gate opener’s deep cycle battery (a simple 4 output charger with extension cords for charging other deep cycle batteries from amazon Battery Tender 022-0148-DL-WH 12V 4-Bank Battery Management System) and this unit has a far superior charging design.
The 4 bank battery tender does a simple fast rate charge then switches to a trickle charge at a constant voltage with 4 outputs.
This unit pulses the battery under charge and features 3 operating modes with different current outputs for different sized batteries. The selections are motorcycle which also works well for SLA gel cells or AGM batteries, standard automotive starting battery, deep cycle batttery, and off.
What makes the CTEK unit special is that it uses a pulse charge in all modes to attempt to desulphate batteries, while the battery tender does not. This method of charging has proven successful in restoring lead acid batteries that won’t take a charge any more.
It comes with a waterproof 12V output cable and a set of clips or rings for permanent installation under the hood of your car. In addition to the LEDs for indicating the type of battery being charged, a second set is provided for empty, 1/2 full, and maintenance pulse charge mode.
There is also a noticable increase in quality between the battery tender and this unit – small details like a water sealed housing and gaskets on the connectors indicate quality in manufacture.
For a single 12V lead chemistry battery this is a useful, well made tool.
