## Description

CTEK’s comfort indicator eyelet is a practical combination of quick connector and an indicator. Easily connects to batteries which are often difficult to gain access to and is great for multi-vehicle use. The indicator shows the battery's charge level simply and clearly with the 3 different colored LEDs. Red indicates a charge less than 60 percentage, yellow is a charge above 60 percentage but fewer than 80 percentage and the green light indicates a charge over 80 percentage. The comfort indicator eyelet comes standard with an end cap attached to ensure the connection stays in good condition while not in use. All CTEK products are delivered with a 5 year limited from the original purchase date. The limited is not transferable and only covers manufacturing faults or material defects. is only honored if product and original receipt are returned together to the retailer. is void if the battery charger has been opened, handled carelessly or repaired by anyone other than a CTEK Power or its authorized representatives.

Review: Great way to be sure battery has a charge - Well built, easy to install and use with Ctek brand chargers. My wife and I don't drive our cars very often, sometimes 2 or more weeks between trips since online delivery and work-at-home are now our way of life. Problem was that newer vehicles really run down the battery, even while sitting in garage. Twice we had dead batteries (ouch!) and I was getting tired of opening hoods to check voltage, put on the charging clamps, removing and closing hood - etc. Solution was to install these connector+monitors on each vehicle. I extended the wires so the connector+monitor end comes out close to windshield - thus no need to open the hood for charging, and I can see the monitoring LEDs just by walking into the garage. I leave the newest vehicle plugged in 90% of the time, only unplugging it when the 2nd car shows "charge level Yellow" and thus needs a top-up charge. Charger is hung from ceiling, with cord easily moved from Vehicle A to Vehicle B. Real time saver, no dead batteries, and no worries about whether I got the hood properly latched each week.
Review: Great Product - This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

## Questions & Answers

**Q: What gauge wire are the red/black leads? if you don't know don't answer.**
A: I had to replace mine and was examining the old one.  The red wire says "18AWG"  Other specs:  E168110  AWM 2651  VW-1  105°C  300V  ET1

**Q: What is the ID of the battery connections**
A: Red positive. Black ground. Same as all batteries.

**Q: Does this work for motorcycle batteries?**
A: Yea it will work:  fine on lead acid/ AGM/no maintenance type - but not for the newer lithium ion type ( say Ballistic for example which don't like tenders and want a balanced charge)  I use this on 2007 Triumph 1050 Sprint and it works great.  The recondition function really work - brought back two of my neighbors dead snowmobile batts that a normal charge would not charge.  I have it mounted on bike and use the light function - it really work - green no issue , yellow yea it will start but lugging and not good for strait - red - don't try it - also low volts on a Triumph are very hard on starter and sprag gear.  Hope this helps

**Q: Is the indicator always on or is there a button to check the charge state on demand? if the former, i am concerned it will help draw down the battery.**
A: The comfort indicator has an extremely small draw on the battery at all times and does not have an on/off button.
