    Extension Cable Comfort Connect Eyelets Problem
  

*by B***O on Reviewed in the United States on January 31, 2019*

Charger/ Maintainer is probably ok, but the Comfort Connect Eyelets do not fit on my side-terminal battery.  When I asked CTEK Support they said there are other optional Comfort Connect Eyeletd... sure enough there are... BUT only descriptions of them... NO PICTURES.  One supposedly was for side-terminal batteries so I ordered it.... the only difference was a larger diameter hole... the eyelet shank NEEDS to be longer... apparently there are none with a longer eyelet shank... DISAPPOINTED IN OPTIONAL Comfort Connect Eyelets.

    easy to use and works well
  

*by K***. on Reviewed in the United States on April 16, 2018*

WOW!  easy to use and works well.  Bought for my Porsche Boxster that I use occasionally.  Porsche contracted CTEK to make their device and, of course, charge twice as much.  I bought straight from the CTEK.  The battery is in much better shape after automatic 8 step conditioning process.  I don't worry about dead battery anymore.

    Trickle battery charger for most anything!!
  

*by K***R on Reviewed in the United States on January 24, 2019*

I have heard no complaints from my finicky hubby about this charger!  He has it hooked to the boat during the cold weather and it works beautifully!
