Unit working perfect for the purpose. I have a vehicle that I only drive like once a month and this does an excellent job on keeping the battery topped off and the car starts every time. I still have no idea if this would extend the life span of the battery if its being "plug-in" for extended period of time.
BTW, company has excellent customer service. If you have any issue with the unit, contact them and they get the job done.
If I have to buy another automatic battery charger for my cars in the future, I will buy again from this company. :)
** Original review **
I have a vehicle that I don't drive too often and I used to just drive it for a day every 2 weeks hoping to get enough juice in the battery to keep it sitting for another 2 weeks. But the plan didn't work out and I had a drained battery.
I ended up buying the CTEK MUS 4.3 to keep it topped off. The charger does what it advertised so far and I have no problem keep it plugged in. I even tried to rotate it to my other vehicle when they are parked over the weekend to keep their batteries topped off.
I don't find the charge to run hot, but I didn't keep monitoring the temperature. I basically just plugged it and walked away, letting it to do its job.
The charger will top off battery, but I don't know if it will extend the service life span of the battery itself. But so far the charger does a good job ... as a charger. :)
What I like about it:
+ small size
+ no need to worry about weather proof of the unit ()
+ do what its suppose to do to keep car battery topped off
what I don't like about it:
- the wire (battery side) is a little short. I wished that they had put a longer wire there
The only note that I have to mention, it WILL NOT work on a battery that has gone down BELOW 3V, so check your battery before using this, and there's no indication for it in the manual or on the display. Here's how you would know, IF you connected the device and all connections are good, IF the Mode lighting/stages on top does NOT light up, and if the device main LED start FLASHING, the batter has too low of a voltage for this to work... what to do then? If the battery is not totally gone, Jump the car, let it charge for a little, then connect this right after. Most likely battery charge would be above 3V and then let this do its magic (may take over a day)... and hopefully you save save your car battery.
Overall, it's the best battery charger you can buy and this older model works just as well as the new one, but at a discount. Get one while supplies last!
I was in such a dilemma deciding between the this CTEK 4.3 vs the Noco G3500. Based on my research, Noco is somewhat newer in the smartcharger game and also has additional features (such as larger Li-ion batteries if u need to charge those which most dont need to) but CTEK is THE OEM charger used by all the premium and exotic brands from Porsche to BMW to Mercedes to Audi to McLaren to Lamborghini, etc! Obviously these car manufacturers chose the Sw3d8sh CTEK for a reason and its because: the CTEK charges batteries in a "smarter" fashion with 8 steps and it's at a higher amperage of 4.3 amps vs 3amps on the Noco which does make a difference in charge times.
I was so close to purchasing the Noco but went with CTEK because: I just needed a smartcharger for my AUTO/AGM needs and not recreational atvs or smaller batteries found in golf carts and such which is what the Noco xan also charge. My opinion is CTEK is the better DESIGNATED CAR CHARGER and the Noco is a decent GENERAL SMARTCHARGER with some extra features.
If u mainly need a charger for your car needs, then go for the tried and tested CTEK charger as it's been great. Its heavier in contraction (seems more durable), display/lights are easy to view, it's simple to use, and it comes with a FULL 5 year warranty! From what I read on Nocos "5yr wattanty", it's not a true 5yr warranty and you have to pay for warranty services? Idk but that doesn't seem like a decent warranty/long wait period in the event a charger fails.

Can also be used as a battery tender if using it on a vehicle stored for the winter.
Update :
It has been a couple of months now and I have used it several times. I dont leave it plugged in continuously (though I know you can with confidence). I use it every once in a while just to make sure I'm charged. It works great. I am very happy with the purchase.
Good to simply select and connect this charger once a month to top up state of charge. Your batteries will then last longer.
Comes with regular battery clamps as well as a vehicle mounted quick disconnect, for when you frequently charge a specific vehicle.
Takes about 4-5 hours to get your battery fully charged and a green light at # 7 on scale.
The snowflake symbol is for AGM type batteries and cold weather maintenance, the tested output voltage was 14.6v which is perfect.
So I don't back up with a connected charger, I place a "Charger On" card on the driver seat.
