Review: Works exactly as advertised. - This product works great. Especially good if you have a sports car that you do not drive every day it keeps the battery topped off so you can just jump in and drive when you’re ready. It has a quick connect system so you can just plug it into your car battery when you park the car.
Review: Great Charger for Car Storage & RECOND Batteries - The MUS 4.3 Test & Charge is my second CTEK Product (the first being the Lithium US for my motorcycle). Please be advised that I may be slightly biased (not affiliated/sponsored by anyone). I purchased this unit specifically for keeping charge on stored vehicles and reconditioning batteries in daily driving cars. Per the user manual, CTEK recommends RECOND once a year or whenever battery is depleted completely. If you’re just buying this unit for the first time, it might be a good idea to RECOND too. It took about 9.5 hours (15:30-01:00 next day) to complete all 7 cycles, including RECOND, on my BMW F13 650i. Even though this car mostly sit in my garage for the past half a year or so, it still kept a lot of juice. Its BMW OEM battery is either 90 or 105 Ah, that would take a longgggggg time to charge if it were completely dead. Yes, CTEK is much more expensive than competitors’ products, but it has automatic sequence to test, charge, and maintain your batteries. Other products out there will certainly get the job done as well, though I’m not sure if they’ll do it as well as this unit. There is a nice feature splitting the charge sequence into a faster bulk cycle (<80%) and absorption (80-100%). Not to mention that it will perform tests on the battery and alternator so you won’t waste electricity to charge if it will just die again soon. Generally speaking, $100 for this product is amongst the best investment for your precious weekend cars. If you can afford to have fun, you should definitely keep a battery trickle charger on hand, especially if you live in a colder climate. You wouldn’t want a dead battery to ruin a nice day out, and you definitely don’t want inferior chargers to damage your batteries.

## Questions & Answers

**Q: Looking for a battery recharger for the small 12 volt in Prius 2011. Will this work-- or is it overkill?**
A: I can recommend this battery charger.  The reason is that performance and usability are very good.
I think it is a good choice to use even if you buy a large car.

**Q: Alternator test work on motorcycles too?**
A: Yes ... make sure the battery is fully charged so you won't get a false result. Switch the MODE button to alternator >> start the engine and hold it at 2000 rpm >> if it is charging less than 13.3V it will light up (BAD) >> 13.3V-14.0V (FAIR) >> and above 14.0V (OK).

**Q: What is the difference of this one from model 56-864?  They seem identical**
A: model #56-864 doesn't check your Alternator to see if it is charging u battery

**Q: Is this unit also good for trickle charge?**
A: The product description and other web references say it will work as a trickle charger. In fact the unit goes into a trickle charge mode after it cycles through the battery tests and reconditioning steps. I have used it as a trickle charger for days in a row on a car that gets little use. So far I am satisfied with the product.

*by J***P on July 4, 2025*

Awesome battery charger and refresher. I have owned an early version and smaller model from Ctek, I lowed that one as well, but this one is faster for car batteries. Love the fact that it does not rust. I also got the optional bumper and it made it non slip and it would stay put where I put it while it was charging.
