| 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 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! |

User questions & answers
| Question: | How long are the cords |
| Answer: | There are only two ways to Efficiently & properly charge the unit, plug it into a house 110 V outlet or Or I use a 4000 W inverter in my truck and I plug the inverter primary into the cigarette lighter and the secondary is 110 V which works great on that Max in addition to charging at the same time many charging tool batteries and led work lights. I leave it plugged in My trucks Invertor all the time while driving and all my tools including the max are always charged and hot ready to go. |
| Question: | Just want to make sure I understand this correctly - you can plug this into the cigarette lighter and don't need to connect to the battery |
| Answer: | I wouldn't count on this type of pack for anything with a motor (power tools, the blender, pumps, etc). I tried running a small fridge off a 400 watt inverter connected to a car battery and that wouldn't work. The fridge only needed ~120 watts running, but to start it's motor the "Surge draw" was ~1000 watts that would put the inverter in "overload" alarm every time. So despite the minimal time of running the blender, that "surge draw" is quite often too much for these small inverters.Also FYI, the batteries in these can give you ~200 watts of power for 1 hour (or 100 watts for 2 hours, etc). That's how long they'll last alone. I've seen in manuals that "You can extend the run time by connecting up another battery via the jumper cables", yet if you need multiple parts anyway I'd be tempted to look at a separate battery big enough for everything and a bigger inverter.One of the best suggestions I can make is get something like the "kill-a-watt" meter and see what power your blender & things need for how long. That meter costs $20, so before spending $100+ on this I think knowing what you really need (measuring the power demands) is worth it. That meter can show you both power draw while running (for inverter sizing) and KWH power use (for battery sizing). |
| Question: | how fast does it charge |
| Answer: | I don't have a CPAP or such, but have seen this question posted many times (look under the similar units like Schumacher XP2260 or Duracell 600 packs). This like those other packs has about an "18 amp-hour" battery hinting it can provide 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, or 3 amps for 6 hours, etc. Many others have said they can get at least 1 night out of the packs if you don't need to run things like a humidifier function or such that needs much more power. Since I don't have the same equipment you do to really know the power use (as well as what settings you need), one of the best ways to find out how long this would last is to get a meter like the "Kill-a-watt" and measure the power use yourself. That meter goes for under $20, so before spending $100+ on this I'd see that as worth it. Based on the info I gave above these packs can provide about 200 watts for 1 hour (or 0.2 KWH). With some of the labels like "400 watt inverter" or such you may think it lasts much longer (like at least 1 hour under that 400 watt load), but it doesn't, so don't expect too much out of it (and that's the same for all packs like this). |
| Question: | What is the float voltage? When the charger indicates it is done charging what is the voltage of the battery |
| Answer: | Yes, you can charge this with many "12V" solar panels that are out there. Just beware that if a solar panels is directly connected up, they can raise the battery voltage to levels over 15V which is considered "Overcharging". So it's best to have a voltage regulator or "Charge controller" between the panel and battery (which will stop charging once the battery is at 14.5V which is "full" for it). |
