User questions & answers

Question:	Why is it not recommended to keep a trickle charger hooked up all the time
Answer:	beats me. i keep mine hooked up from 12/31 to 4/1 and only then do i take it off. my understanding is that you do not need to disconnect it-it powers down on its own, but you mught want to find the user nistructions and check me on that. good product if youre not in a hurry
Question:	how fast does it work
Answer:	if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you
Question:	Why is this not available in California
Answer:	Charge for free! Buy a low wattage solar battery charger/maintainer at Harbor Freight instead because it works very well maintaining the battery charge provided that the battery is fully charged before hooking up this solar charger.... it will only maintain the charge. Not made to fully charge a discharged battery. Point the solar panel southwest to get the most out of the sunlight during daytime. I have used this $9.99 if on sale gadget for years now on my boat and car and has not failed me yet. It comes with all the hook up accessories needed. I have not used the boat for 2.5 years at a time and the gel battery is as good as when I installed it 7 years ago. My car wet cell battery also is as good as when I first installed it and I only use the car abroad every 12 months when I am in town for 3 weeks. Car or Boat batteries Gel or not will not last it's lifetime if it is always discharged and recharged. Maintaining the charge is key to it's longevity. Good luck! No need to blame anybody. The State of California is an environmentally conscious state and that is a good thing for everybody.
Question:	Can this be used to charge an AGM battery
Answer:	Stupid me, but don't all lead acid batteries use the same chemistry? I've read only that 6-cell lead-acid batteries should never use a charging voltage exceeding 14.4 volts, since water will begin to H2 gas and O2 gas above that. You risk explosion and loss of electrolyte beyond that. Explain why this is different for AGM, Flooded, and Gel batteries!

User questions & answers

Question:	What is the ac input voltage & frequency
Answer:	Depends where you purchase it. If purchased in USA comes with a 2 pin plug/cord and set for 120v but elsewhere set for local market voltage and plug e.g. in UK has 3 pin plug and set for 240v.
Question:	Why does amazon say this won’t work with a 2007 Porsche Cayman
Answer:	Our MXS 5.0 (40-206) is a 12V, 4.3 amp charger recommended for lead-acid and AGM batteries up to 160Ah. If your battery meets this criteria it will work fine on your vehicle.
Question:	Will this work for a 2017 Porsche Macan S
Answer:	Will this work with a 2018 Porsche macan
Question:	What’s the difference between this mxs 5.0 charger and a mus
Answer:	Don't agree with D. Raupp: the number is not the amps it can put out but likely a number larger that 4.3 to show that it's a newer version in their line up. This charger is the next generation of the 4.3 with updated features/improvements, also with an added feature - the temperature sensing/adjustment. Called CTEK today and they said that 5.0 replaces the 4.3 which they are phasing out. This unit charges with several different amps: 0.8A; 4.3A; 2.5A; and 1.5A and switches automatically between them depending on which phase of the charge cycle it is in.

User questions & answers

Question:	What is the difference between the sc1280, sc1281, sc1323 and sc
Answer:	The length of warranty on paper doesn’t matter because getting them to act on it is difficult. They wanted me to send the charger to them at my cost and wait without a charger for 6?weeks
Question:	Can this be used to charge lawn tractor batteries
Answer:	Yes, they are plastic. And Yes the break. My negative terminal just snapped in half... Not happy. Why couldn’t they just use metal??
Question:	What is the warranty on this product
Answer:	It will work with any brand of battery.
Question:	Want to charge battery in vehical (suv). is it safe to do in enclosed garage? thinking yes, but please confirm
Answer:	The clamps are metal on the inside (obviously), and a durable plastic on the outside as insulating covers. Looks to be pretty durable, I've had no problems with them. But then, I tend to take care of my toys! :-) This unit, by the way, was an excellent investment...after having owned several less-capable chargers. This one restored my Yellow Top battery back to its full capacity in short order! I own a Tahoe Hybrid and had installed the Yellow Top as a result of standard batteries not holding a full charge after a year or two, and often draining when not running the Tahoe at least once every 4-5 days or so. Can connect full-time to the battery the accompanying cable, making the use of clamps unnecessary! Just have to remember to unplug it!

7-STAGE CHARGING AND MAINTENANCE MODES

1. Desulphation: Pulse charges the battery to break down the build-up of lead sulphate crystals. Lead sulphate crystals can occur when a battery has been discharged or left unused for a period of time, seriously affecting the performance and lifespan of the battery.

2. Soft Start: A slow steady buildup of the charging process that limits the power supplied to protect the battery.

3. Bulk Charge: The main part of the charging process where 80% of the charge is applied.

4. Absorption: Fully charges the battery by slowly reducing the charge rate to allow the battery to absorb more power.

5. Battery Test: An automatic test to determine the battery condition after charging. If further charging is required, the Recondition stage is selected. If fully charged, the battery goes into Float status.

6. Recondition: Unique charge state to recover deeply discharged batteries.

7. Float: Maintains the battery at 100% charge without overcharging or damaging the battery, allowing the Smart Charger to be left connected to the battery indefinitely.

User questions & answers

Question:	What is the warranty for th
Answer:	The user manual does not say anything about slow charging; it might charge the battery to a point if connected to it but it won't be slow. The car battery charger can charge small electronic devices via USB ports, but the charging circuitry that controls, monitors and limits the amount of current that goes to charge these devices is in the small electronic device itself. Customer support might be able to give you a better answer. The customer support number for the car battery charger is listed as 1 (888) 965-5888 in the user guide.
Question:	does this work with optima yellow top battery
Answer:	The cables are about 8 inches long not including the clips. However since the power pack is only a little larger than a cell phone it is easy to get it within a couple of inches of the battery posts so the cables do not have to be long to reach. That is the great thing about these little starters....they work without having to have space to maneuver a car or to need long cables.
Question:	Why does it say not to charge a dead battery in the warnings? Is that not what it’s meant for
Answer:	It charges using a provided USB-C cord but you must provide the wall or auto charger.
Question:	Charger says to connect cables when they are connected
Answer:	The instructions say at least 20%.

User questions & answers

Question:	Does it come with directions to replace
Answer:	No it does not come with directions. But it fits excactly where the old one is replaced. So I made sure it hooked up exactly the same way. But I also took a photo just in case. Hope that helps. It did work out perfect though and a lot cheaper than the $65 dollars Frontier wanted to charge for a replacement.
