    Rated 5 out of 5 by CTEK Car Battery Comfort Indicator This product works well with the CTEK car battery chargers. Fitted to my car makes easy connecting possible.. 09 December 2014
    Rated 5 out of 5 by Perfect and simple to use. Just the job for my boat. I bought the comfort connector along with the charger allowing me to just plug in when a charge is required as the connecter remains fixed to the battery all the time sowing the batterys state of charge. Perfect 04 December 2013
    Rated 5 out of 5 by Capacity at a Glance Great product, it gives you a visible warning of potential battery damage by sulfating plates. I mounted my device in front of my battery, which enables me to check my voltage at a glance via the traffic light LED's. Adapter cables with plugs are available, just visit the Ctek website. I connected my solar panel to this Ctek Car Battey Condition Indecator. This product workes great. Ideal warning for batteries standing idle before failing. 11 June 2013
    Rated 5 out of 5 by Traffic lights I like this! It's nicely made and does the job simply. Encourages you to buy CTEC accessories as it has clever plugs so you can join on to a charger or a corresponding product. I think it would fit a motor cycle or scooter so , it can go around the garage. Cost wise will allow to have one for each vehicle, so no excuse for a flat battery. 20 April 2013
    Rated 4 out of 5 by Nice little add-on Nice accessory for any ctek charger. Very easy to connect to battery but would prefer if it stated the size of the ring terminals on the website 13 September 2011
