Schumacher Electric Battery Charger and Maintainer, SC1323, 4-in-1, Fully Automatic, Battery Tester, 15 Amps, 6 Volt, 12 Volt, for Car, SUV, Truck, and Marine Batteries

This charger is portable and easy to use anywhere you can obtain electric service. Not only is it great for charging, but it great as a battery maintainer if you need a fully charged battery while performing diagnostic. I believe this is the best battery charger on the market while not breaking piggy bank.

The charger is a good product, but it took reading a review of it in order to make sense of the instructions and front panel indicators. It has a low profile that helps the hood to shield the unit from the weather. The percentage indicator is a real plus. Hopefully it's cooling fan will help it last longer than the older model it replaced.

I'm using this modern charger to maintain a new Walmart car battery and it seems to be working so far. I would not use it for anything smaller than a lawnmower battery. I used it on an agm alarm battery and it cracked the case while charging overnight. The desulfation part did not seem like it worked because the battery would not stay at 12.6V and gave a FF05 error.

I have always trusted this brand for vehicle batteries. However, I am used to using a very old battery charger, this one is updated and new so it is very easy to use. As I have always charged my vehicle batteries over night, this one did not disappoint me. So the charging speed was not an issue and worked well for me. In short, it charged my battery very good, the cord length was about the right length and the information lights where bright enough to see them in mid-day.

Bought this to charge batteries for an automatic gate mainly but also for general battery needs. 1st battery i tried to charge went into Sulfate mode and dang near exploded my battery. 2nd battery did as well but i caught it before it did any damage to the battery. Both were new batteries less than 6 months old, standard 7aH batteries. Charged the 2nd battery that didnt get ruined with a different charger and it worked just fine. Used this charger to top off my boat battery that was at 75% to start and it did ok. The battery that almost exploded(swelled and smoking) was at 10% when it started so i think thats why it went to sulfate mode. Regardless if this "smart" charger is too stupid to not explode your battery its worthless except to just top off a slightly discharged battery. 12/7 update: Tried to use this charger to charge up my tractor battery after a new cable replacement. It will start to charge at 12 volts and then switch to 6 volts and says its complete when the battery is still just barely charged. Switched rating down to 1 star as this charger is completely useless and garbage. My 20yr old manual stand up wheeled charger charged my battery just fine. Its also a Schumacher brand but now the name obviously means nothing.

Works well

Very fast delivery and easy to use worth the price ,keeps my car charged at full everyday in the winter ,need new battery in the spring for now its ok .

The instructions don't make it clear when the charging operation is done! And the display on the unit is too cute for its own good! So I have included two photos to help users. The first photo: >The green "IO indicator" means that the unit has been plugged into the wall and is turned on. >The yellow "ON indicator" means that the unit is charging. The second photo: >The green "IO indicator means that the unit has been plugged into the wall and is turned on. >The green "battery shaped indicator" means that the battery is charged.
