    • Brought My Battery Back To Life
Color: Gray
I am in no way a mechanic, but I like to read and try to solve my problems if possible. I've had some issues with my foot and have not been able to drive for several months. While I was in the hospital my battery completely died. I have been experiencing issues each winter with the cold since I park outside and the cold weather drains the battery. Previously I was able to jump start the battery without issue. My soon to be son-in-law installed a new battery and I would start my car every couple of days. In the last cold stretch I did not make it out to start my car for a week and the battery died again. I did my research and found that the Schumacher Electric SC1281 would recharge my battery and also test out my alternator. I found this helpful although I did not expect my alternator to need replacing since it has not been that long since it was replaced. The Schumacher Electric SC1281 was a little heavy to carry if you are a smaller person, but the case has a handle so it is kind of a wash for the portability. Make sure to have a long extension cord as you will need to plug in the charger to an outlet. The clamps are marked with the positive and negative symbols so it is easy for a novice to use. Turn on the charger and the device will automatically detect the battery type that needs the charge. The user guide was helpful, and explained the charging process and how long I needed to wait and what the various indicator lights mean during the charging process. The Schumacher Electric SC1281 has an automatic shutoff which is helpful for the novice user and prevents damage to the battery from overcharging. Also, the Schumacher Electric SC1281 solves my cold weather problem in the winter. The device also provides a trickle charge if plugged in overnight in cold weather. From what I have read, in simple terms a trickle charge means the device will give the battery enough of a charge to prevent dying in cold weather. Of course, I might win the lottery and move to Arizona before the next winter hits. Hey, a person can dream right? In summary, the Schumacher Electric SC1281 brought back my relatively new battery from the dead after a cold spell and I can use this to make my life a bit easier in the cold weather from this point forward. The cost was worth it to me as I can use this as long as I park outside in the colder months and not worry about a jump start. ... show more

    • Solidly built, charges quickly. Super happy with this purchase.
Color: Gray
I ordered a Craftsman charger that arrived yesterday. It was put together with the inner components upside down so you couldn't set the charge and it weighed maybe a pound. I requested a return and bought this unit. Am I ever glad the Craftsman failed. The Schumacher proudct has a bit of weight to it and it does the job. Simple to use and charged the battery fast. I'm not sure how long because I came back inside but I checked after about 45 mintues and the battery was good to go. Super happy with this purchase. ... show more

    • Voltage is weird; instructions inadequate
Color: Gray
I'm charging a 12v long-dead battery still in the car. There are NO instructions as to how to get the charger into desulphating mode, nor how to gently charge a long-dead battery. Without pressing any buttons, when the cord's hooked up, the unit drops almost immediately into 30A Boost / AGM battery / Charging mode, it seems without waiting 30 seconds (11.Power-up AutoStart) or 10 minutes (11.9) like the manual claims [update: for the other car I timed it. Now it's 30 sec. Subjective error, or?]. Then the unit readout says it's charging at 12 volts. But the actual charge at the terminals, while charging, with the clamps hooked up, is 15.5 volts. Maybe this is needed to kick-start the battery. I don't know. We'd need a chemical engineer battery specialist to cover this. But for a car electric system designed for 12 volts, it makes me feel uncomfortable that it might not be healthy for the car/battery. So I switched from 30A Boost to 6-12A Charge. Currently [har,har] the battery is charging at 13.8v, varying in a pulsing wave down to a couple volts every few seconds. Maybe this is finally the desulph mode, who knows. --Unit should reflect actual voltage at the terminals, not ideal desired voltage, while charging. Or at least alternate between the two of them, along with percent. --Percent charge seems way off, again reflects surface charge, not the deep state of the charge. --Manual needs clear instructions as to how best to recharge a drained battery, for the following two cases: (1) you care about the health of the battery, and want to renew it and get it up to speed, gently, safely, no matter how long it takes; (2) you don't care about damaging the long-term health of the battery, and want to charge it as fast as possible. These are complete opposites. Second one is probably covered by BOOST, but should mention you're going to keep damage on the battery. First one, the most likely scenario in '20 COVID with unemployment and folks not being able to afford a new battery, needs to be covered clearly in the manual and on Amazon. --Manual clearly says "if START button is not pressed within 30 seconds, but a battery is properly connected, the unit will automatically switch to CHARGER mode." If my observation was correct, this language should be edited to something like "...will automatically switch to CHARGER mode sometime within that 30 seconds." I could be wrong. --Manual and Amazon instructions need more discussion about how excess voltage is necessary to pack electricity into a battery that's trying to push it OUT by its own self; how high this voltage can get; why it's not being reflected in the machine display; and steps taken by the manufacturer to avoid excess battery overcharging, also overheating. --Note a very-fast-charged battery will maintain relatively high voltage on the surface terminals for a while, but not have a strong charge on the deep parts. It all depends on the amount of amp-hours you push into it. Voltage is like the water-pressure on a hose, while amp current is the flow rate in "gallons" of electrons, basically how fat the hose is. You can have a high-pressure waterpik or power scrubber with a tiny diameter, that really pushes the water out hard, but not a lot of it. That's high voltage, low amp current, like most of the dinky 0.5A chargers on the market. You can have a fat firehose turned on low that gives you lots of gallons but no pressure. That's what you want normally, that's high amps and low voltage. Fills up your battery reasonably fast. A 30A system at 15 volts is 450 watts, that's half a hairdryer, that's a firehose turned on medium high. Good for filling up a bucket fast, but you wouldn't shower your aging grandmother with it. A compact car might have a 70 amp-hour battery, so if it's almost half-drained to 40 AH remaining, the 30A boost will take an hour to top it off. And if it's almost completely dead at only 10AH left, the 30A boost might in theory take 2 hours to fill it (30 + 30), back of envelope estimate, ignoring "stadium-filling" charging effects. But I'm not sure how good that is for the long-term health of an aging battery. So I'd really appreciate clear step-by-step instructions on how to desulphate a battery with this unit. Thanks so much. ... show more

    • Easy To Use, Informative Readouts, Fast Thorough Charging, Built To Last
Color: Gray
I've had an old Sears 50amp charger for over 30 years, and it always provided a great charge, and meters that let me know the condition of the battery being charged. Sadly, due to my own carelessness in attaching the cables, it burned itself out. Finding a replacement would be difficult as a lot has changed in charging products in the past 30 years. Thankfully, this Schumacher 100 amp (starting) is well-built, has heavy-duty components, and up-to-date technology that makes charging easier, faster and satisfying. Yes, satisfying, because a well-built product that works as claimed, and gets me out of a tight spot is a product that pleases me. I like this so much, that I will be looking at Schumacher for other automotive products I might need. We all know that most of our products are made in China, and though we might wish to buy American, that is largely only a wish. But, what makes a product from China great is the oversight by concerned individuals, excellent quality control, and customer commitment. Schumacher is apparently doing all this things. We suspect that many products come from the same factories, with just a different box and labels, but oversight by tough folks makes all the difference in the world. Price is right tool ... show more

Extremely dangerous battery charger. This charger is in BOOST mode by design when it is first turned on. I was disappointed and worried to see this when I first used it but of course I selected the lowest setting to gently charge the battery. I walked away and although I didn’t know it at the time, the electricity momentarily went off and came back on. This resulted in the charger beginning again in BOOST mode which within a short time made my battery explode. I heard a loud explosion, found the mess and noticed later that the electricity had blinked off in the house and shop as evidenced by the clocks losing their settings. If I had been standing by the vehicle, I could have been blinded. Before someone thinks I did something wrong, I assure you I did not. I’ve used battery chargers for decades having spent much of my working career as a professional mechanic and as a drag racer and engine builder. It took a stupid engineer to design a battery charger that boosts by default upon startup. The vehicle the battery exploded in was my tractor and thankfully not a car with shiny paint. Still, I had a mess and I still have no paint and a rust and corrosion problem even though I did my best to neutralize the acid. Again, the battery charger was connected correctly and I immediately switched it from boost to the lowest amperage setting which is where a charger should begin by default, NOT on boost! I finally got to speak with a person at Amazon after much wasted time and effort and was told there was nothing he could do. After much conversation, I told him I would then proceed to seek damage compensation whereupon he claimed to have asked for and received an ok to grant me a refund. I bought this charger in good faith because it is a well known brand and I trusted Amazon to gladly refund or replace if necessary. I was wrong on both counts. I will never place an order for another battery charger but will instead try one out in a store or buy one in a store and test it to be sure it doesn’t come on in boost mode. If it does, at least I can return it before I use it. Be safe, people. Some products are engineered with stupidity even if they are well known brands. Also, I always try to buy American and union made products but we can’t trust anything. I would rather give it a negative number of stars. It doesn’t deserve one. Good luck and try to be safe. ... show more

    • Perfect for recharging car batteries
Color: Gray
I have used at least a dozen times to extend life of an aging lead-acid car battery, as well as to recharge a new-but-depleted lead-acid battery after the ICCU popped in an EV . I typically use with a 12-gauge 50' extension cord, since the outlet is too far away. While it has multiple functions for engine start, power boost, etc., I only have needed to use the standard recharge feature, as I have been content to let it charge over several hours. Great product. ... show more
