Battery Tender Recommendations

For those of you who use a battery tender, what brand & model do you use? Did some researching this weekend and looked like the CTEK CS One would be a good option. However, I don't know if they stopped making it or is just hard to find (excluding the exorbitantly priced ones on eBay). Curious as to what others are using.

CTEK MSX 5.0 or the CTEK MUS 4.3 (which includes some test capabilities). Get the cigarette plug adapter too.

On Amazon, the MSX 5.0 is $95 and the MUS 4.3 is $125. The adapter cord is $16.

FYI, the Corvette branded option is a basic CTEK.

I've had my 2020 on a CTEK MUS 4.3 daily for over three years. Best of all tenders I've owned, and I've tried Deltran, Optimate, etc.

I love this charger. It isn't available any more but look into the replacement. Wide array of data and function. I love it.

I have also been very happy the many Harbor Fright battery tenders that I have.

I have used both a Battery Tender Plus and the factory branded CTEK - both work very well. For the CTEK, you have a number of options to choose from.

My car came with the Corvette branded basic CTEK from Chevrolet and it works just fine. I have several others in my garage, but I decided to use the one that shipped with the car.

I've a lot of vehicles and have at least one of each of these brands. All are fine. However, over the years I've had a couple "Battery Tenders" die... never with Optimas or CTEK. Also, I've banged around the Optimas more than the others without issue.

CTEK charger is what I use. Don't forget to buy the CTEK Comfort Connect plug that you'll need to adapt and charge through the frunk charging port.

On the CTEK , You may find the :extension cord" that goes between the unit and the car helpful. @$15

CTEK - I have an MSX 5.0 and a 7002 which is a huge maintainer for bigger batteries. My primary car which doesn't get driven that much is always on the 5.0 if it is standing still in the garage. I especially like the complete cycling feature of the 5.0 which won't overcharge a battery like a "battery charger" will.

Just about every premium brand car manufacturer purchases from CTEK then rebrands them for their car models. - Corvette, Ferrari, MB, Bentley, Aston Martin, Lamborghini, Maserati, BMW, Porsche, RR, Ford GT, to name a few.
