15A Car Battery Charger and Maintainer, 4-in-1 Solution, for 6V/12V Power Sport, Automotive, and Marine Batteries, SC1280

This Schumacher charger is absolutely fantastic! It’ve used it on everything – lawnmower, motorcycle, car, camper, and even marine deep cycle batteries – and it performs flawlessly every time. The controls are simple and intuitive, and it charges batteries surprisingly fast. I especially appreciate the versatility – it handles LiPo, AGM, and submerged lead-acid batteries with ease. The built-in overcharge protection gives me complete confidence. Truly a top-quality, reliable charger!

I did a little of research, shopping, looking for the best charger, brand and features. I have a 25yr old large charger on wheels that I realized was not charging correctly. This charger reads the battery, if bad automatically goes into repair mode. If good starts charging at the level needed, shows the % charged then shuts off when at 100%. No overheating. Most I found in this price range we unknown names. Schumacher has been around for years very reliable so far.

The Schumacher Electric Car Battery Charger is very light, which makes it easy to carry, store, and move around when needed. Despite the low weight, it feels well-built and charges reliably. It’s straightforward to use, does exactly what it’s supposed to, and is perfect for keeping a battery topped off or bringing a low battery back to life. Bottom line: Lightweight, easy to use, and dependable—great charger for the money.

UPDATE: DO NOT USE AS CONTINUOUS battery "tender" because there is no way to change the default setting it uses when it is initially plugged into the wall. NOT recommended because if you have a power failure in your house, when your electricity comes back on, this thing begins charging at high current, selected for an AGM type of battery. Does not matter if you previously set it to low power/"GelCell," for example, as a trickle-type charger. The risk is that you will cook a smaller battery, or one that is a traditional Sealed Lead Acid like most vehicles run, because this unit defaults to the higher voltage and current of an AGM. Previous review follows. This model has a few problems, starting with a bad cooling fan or a bad thermal sensor that allowed the unit to overheat. The blower failed to come on, and the plastic housing got very warm on the bottom, although the charging took place as normal. I returned it for an exact replacement. On the substitute one, the fan turns on when the inside needs cooling. The fan will shut off unless needed. The date code on the defective fan was 2022, and the replacement is 2023. Next up, I consider the level of automation a problem. I wish it had a "manual" mode that would let the user select and match some specific charging functions. For example, when first turned on, the unit defaults to an "AGM" type of battery at the unit's maximum 15 Amp charging rate. This could be a problem, because it's possible the user intends to charge a small AGM, gel cell, or a small lead-acid battery, for which the high current is not appropriate. The default should be on the safer, lower current setting, or it should be programmable by the user as the "default." The directions do not explain how the automatic "desulfation" function is initialized. The user must assume the automatic charger simply analyzes and "knows" a desulfation is needed. With no indicator to tell the user the function is underway, I don't trust that it is, or is not, being done. A query to the manufacturer was not answered. Earlier, instead of answering my question of how the cooling fan is turned on, I was told it was against the law to open the case. (not true) Design problem is next: The digital display is incomplete while charging. It will show a generic "12V" setting when that voltage of battery is connected, but fails to show the actual voltage measured at the clamps. There does not seem to be a way to have the display alternate between actual voltage and the percentage of charge that has been reached. The unit has the ability to measure the real voltage, and does so when initially powered up. It should be easy to assign the real voltage to the display while charging is underway, instead of a dummy "12V" The older model SC-1200A is much better. I have opened and repaired my 2009 example of the SC-1200A after a noisy fan bearing started acting up every cold winter. A $8.00 replacement fan from Amazon, mounted inside on the circuit board and frame, like the original, and it's back in service. When power is lost to the SC-1200A, it does NOTHING but come on and display the actual voltage at the battery clamps. It waits for you to initiate the charge rate and type of battery by pushing the selected buttons. Very nice & safe. The SC-1200A is HIGHLY RECOMMENDED, if you can find one.

I bought a new Die Hard battery for my Chevy Truck 8 cylinder. It sat for about 9 months with the battery unhooked but still in the truck. It needed a jump with my NEXPOW 2000A portable jump starter which I highly recommend. After that I couldn't get the truck to hold a charge. I tried my old timey 4A battery charger for days at a time. After charging it would start but not hold the charge. I thought I might have to buy a new battery. I bought this unit because it claims it will desulfate the battery. I hooked it up and eventually it did go into "SUL" or desulfate mode. At first, I unhooked when it said that because the "bad battery" LED also lights up. I read the instructions again and that is normal. I thought maybe I messed up the progress, but after re-hooking up the charger it is smart enough to go do what it needs to do. Battery is now holding a charge like brand new. Just went on a trip for 10 days and truck started up no problem! This charger is ingenious and well worth the money. Also extremely light weight and leads are plenty long. I have to use an extension cord cuz my truck is on the street. I leave the charger under the hood and run wire out from under. If I could leave the extension cord through the yard for months at a time without the lawn guy chopping it up, I would leave it on to trickle charge as well. I highly recommend!!!

This works very well.gives you a lot of feedback.

Good price point and easy to operate especially for someone knowing very little about auto mechanics. Simple instructions and had my car battery charged in a few hours from being completely dead. This is a 2011 car with all bells and whistles with very little driving so a dead battery is common and this charger fits the bill perfectly. I like the fact that it prevents overcharging. Easy to use and I would recommend. I am a 74 yo lady and if I can use this anyone can.

I need to change this item

Excelente producto funciona muy bien mantien mi batería de la moto cargada cuando no la uso por dos o tres semanas y se comporta excelente solo le agregaría la función de ciclo profundo que no lo tiene pero buena relación calidad-precio y además Schumacher es garantía de equipos

Very poor instructions Charger trip my home circuit breaker waiting for Amazon to pick up return item Not recommended

Mon conjoint est satisfait. Polyvalent et sécuritaire.

La calidad de los componentes es excelente, su funcionalidad es muy buena, había utilizado de esta marca de menor capacidad y era bueno, pero este es ecepcional
