Review: Es fácil de usar y cumple a la perfección con su finalidad
Review: Cteck is a very reputable & well established manufacturer of car battery chargers. The charger is well made, well designed and very good quality. It is very easy to use and very simple to connect it to the car's battery. It will not hurt/damage the car's battery even if I have kept this charger connected to the battery continuously for weeks while I am on vacation. I know for the fact the many luxury car manufacturers such as Mercedes Benz & BMW do sell its "brand name" car battery chargers, but their chargers are actually made by Cteck.

## Questions & Answers

**Q: Does this model come with the correct connect for Husqvarna lawn tractor with charger plug in by battery  indicator?**
A: I reseached this question and to the best of my ability it appears yes it is.

**Q: Do the ctek cables use sae connections or are they unique to ctek??**
A: Our Comfort Connect System is unique to CTEK. We do offer an SAE connector that is compatible with many of our chargers 
(part# 56-564).

**Q: Will this device perform well for batteries found in cars?  this page says "for charging batteries in motorcycles, jet skis, atvs and lawnmowers."**
A: The US 0.8 is designed for charging 12V lead-acid batteries up to 32Ah which are typical size batteries in motorcycles, jet skis, atvs and lawnmowers. It is not designed for charging larger car-size 12V batteries.

**Q: How long does it usually take to charge a car battery?**
A: It depends on the state of charge.  The CTEK US 0.8 would take a very long time to do a weak car battery.   Could be 12+ hours.  But  OK for maintaining a fully charged battery.   I have one but use it on a small battery for an emergency generator.  Perfectly fine for that and similar smaller batteries like a motorcycle.  While I would certainly recommend CTEK (I have 6, 3 different models), I would consider a more robust version for a car if charging time is a concern.
