CTEK Reviews 

I purchased a CTEK 5.0 which had a five year warranty. It's a fantastic product but a small issue developed in the 4th year. When I reached out to CTEK, they were very professional and responded to my issue immediately. After forwarding the requested documentation re: serial # etc, they provided me with a new CTEK 5.0! This is one efficient company and a joy to deal with!!

Top quality product I maintain a small fleet and the units are essential in our business

Effective support to a great product range. Have recommended CTEK chargers for years.

I needed a part not sold by CTEK in Sweden for my CTEK installation and CTEK support ‘rummaged’ around, found it and posted it to me in Australia - above and beyond

I had a fantastic experience with CTEK support because it was easy to make contact with an actual person, they were patient working with me, and they were always responsive will excellent feedback as well as pertinent questions. I was pleasantly surprised to find such a high quality of technical support available these days. I have four (4) CTEK chargers for various vehicles. I certainly recommend their chargers and recommend the company based on their technical support.

I have used the (time to go) charger for a few years now for the maintenance of my classic car batteries, with great effect, unfortunately the unit suddenly stopped working. I reached out to CTEK to see if I could get a repair, & to my delight I was informed it was still under warranty, & a replacement is on its way.
How refreshing to deal with a company like CTEK who go above & beyond with their excellent customer service.
Well done it’s 5 stars from me

Great product (MX10S battery charger), bought for my AGM 12v leisure battery as it has a specific AGM mode. Multi step charging sequence that really looks after the battery with clear indication of progress on the charging steps.
Also bought comfort connect lead for easy one click charging connection but damaged the inline fuse when installing - customer service excellent in answering query and sending replacement - rare to get such good service these days. Very satisfied customer!

My CTEK Polar charger is a rock solid device, this winter it hit -54 Celsius and it did not skip a beat keeping the battery in my new truck maintained. I had an issue with my alligator clips and Leo from customer service was extremely helpful and in under 2 weeks had a replacement delivered to my house. Great products and great support! -Adam

Quick responses to my emails.
Don’t leave you hanging.

I sought out CTEK because battery manufacturers recommend them. As I now have 3 different battery types I chose the CTEK that handles all 3 including motorcycle. I’ve used it on all of them and it works nicely. And it is reasonably priced.

Bought the product several years ago. Worked great up until a couple weks ago. Discovered it had a five year warranty, so I contacted their support organization. I was not expecting much, as in most situations, product support is totally lacking. Not true with CTEK. I got instant response. I told them what kind of problem I had and they immediately facilitated a replacement for the failing product. What a refreshong change considering some of the support (or lack of) on most products. Keep up the good work.

Great device, smooth delivery.

Smart charger works great.
But it only came with battery clamps. Had to buy ring terminals for a permeant connection and an extension cable to reach mounting location. Then realized the extension cable needed 2 male ends to connect to the ring terminals and the charger so had to buy another extension cable and cut it to splice the male end on.

Support is great! NjordGo + NanogridAir combination is GREAT!

There is a minor inconvenience with charging the Audi Q4, but I can’t say for sure whether it’s caused by the charger or the car. My guess is that it’s the car.

Fast shipping. Great product. Please try to stock accessories. There is no cs one bumper and no cs one connect u terminal 40-377 on the CTEK website

Outstanding customer support and communication.

Excellent...Shipped Fast and Packaged well...price for the kit was cheaper from CTEK than the maintainer alone on amazon...

The product (CTEK MXS 5.0) is excellent. Absulut high quality, I can easily use it.

I had a few questions via e-mail, and received an immediate and accurate answer from customer service CTEK support! Thank you.

I own a 30 yar old Bentley Continental and bought a CTEK in June 2023 to maintain the battery mainly through the winter months. It was all working fine until this year I started getting intermittent stage 4 errors - battery not holding charge.
I emailed CTEK about my experience and their support team replied within hours, they asked a some questions and made a couple of suggestions, asked for a photo of the serial number and proof of purchase. Then I received a link to a form for a replacement unit - this I completed, received an email that a new unit was being sent out. Excellent company to deal with.
