   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.

   Easy tips (that are not in the manual or on any video)1) TESTING the battery: don’t plug in the CTEK MUS 4.3 (into a power outlet) just hook it up to the battery and flip the mode to the appropriate one you wish to test.2) Charging the battery: Plug into the wall, clip on the battery, select an appropriate mode.I had a DEAD battery. I refilled it with a proper mixture of Epson salt + distilled water. I put on an older charger that did steady 2 amps for 24 hours (caps off). Once it was “boiling” I removed the older charger and place the CTEK on the battery. Set it for reconditioning, did this twice. The battery holds a perfect charge.Note: Epson Salts + distilled water will work. I didn’t need to remove the old battery acid. The batter was 22 months old, it was just sitting for almost a year.250g Epson salt + 16 oz of Distilled water.Magnesium sulfate and lead sulfate undergo a single replacement reaction. Magnesium metal is more reactive than lead, so it is capable of replacing it in the plates. Take note; Magnesium sulfate is highly soluble in water. With this, lead metal is gradually restored and removed around the plates

   CTEK makes excellent chargers, but the extra cost testing function on this model is simply not needed. When you read the directions, it becomes clear the “testing” function only indicates your battery’s voltage. The same information can be obtained by checking your battery’s voltage with a multimeter. I returned this model and bought the MXS 5.0 instead.PS: “Snowflake” on this model and “AGM” on the MXS 5.0 are the same setting. Also, the battery clamps provided with either model have short connecting wires that are most suited if you plan to lift your hood and connect the CTEK each time you use it. If you want to keep your CTEK on a nearby wall and connect it each time you charge, you will probably want to buy the accessory Comfort Indicator Clamps, which have long enough wires to get the connector plug outside your engine bay, where you can reach it without lifting the hood each time you charge. Depending how far the CTEK is from your car, you may also want to buy the Comfort Connect Extension cable.

   This is my second CTEK Mus 4.3. The first one was recommended by the BMW Motorcycle shop. That’s all they used. So I bought one online. That was summer of 2013. My m/c battery is still running hard, and YES, my CTEK is still maintaining my m/c battery, like new. The second one is for my Exmark Zero Turn Mower. Would recommend to anyone.

   This was a second unit in our family… bought by my son for his car. The first unit bought over 2-3 years ago and regularly used is still working fine. The new unit looks like the old except that the output cable now is as robustly constructed as the AC power line. The old output cable was just a 2-wire cord (unprotected). Otherwise same as before…. works great…. simple operation… and very effective in keeping car batteries from being from being flat due to prolonged lack of use.

   My BMW spends most of its life in the garage and so the battery dies. Once I figured out this charger it charged my battery from dead to life and keeps the car top’d up when its not in use. Much cheaper then the BMW OEM charger

   I like that there are several modes, including a desulphation mode. They are not intuitive so keep your manual nearby. You’ll need it anyway to remember what the seven stages of charging mean.Great charger/maintainer for autos or motorcycles.

   I got this for my ’05 Z4 which I drive regularly but lately I find myself driving my Lexus RC F Sport more often. My Z4 has been a pillar of reliability ( I know, I know! Don’t laugh, but it actually is.) so when I get in it I want it to start up immediately so I can proceed to drive it like I stole it. After some research, I came across this highly recommended CTEK 56-959 and it’s easily the best investment I’ve made to my Z4.The instructions are not as bad as everyone says, but it could also be because I watched quite a few YouTube review videos about it. This was an easy plug and play that does exactly what it said it would do. It works.If you need a battery tender, get this!
