The SC1309 can fully charge a 105Ah battery in about 16 hours. It’s easy to operate and includes desulfation and float modes. While a bit heavier than our other recommended best car battery chargers, the Schumacher SC1309 is versatile and fast-charging. The built-in tester can detect battery charge level and even has some diagnostics features. Unlike the other battery chargers on this list, the Schumacher SC1309 is capable not only of charging a vehicle but also providing a jump start. We like the preprogrammed multi-stage charge cycle, and the only settings you must choose are a 12-volt versus 8-volt battery as well as standard, AGM, or reconditioning mode. This is within the ideal range for a 12-volt car battery. This charger put out a consistent 14 volts when we attached it to our test battery. They are rather small, and while we didn’t have problems getting them onto our test car battery, they are of noticeably lower quality than other car battery chargers. However, the CTEK loses some points because of the lackluster alligator clamps.

The CTEK is easy to start and features the most straightforward, easy-to-understand manual of the car battery chargers we tested. It’s soft and won’t offer much protection. The carrying case fits everything nicely, but it could be more robust. In addition to the charger, the CTEK includes: Battery type(s): Standard (wet), calcium (Ca), AGM, and gel.Because of its automatic voltage detector, you can use this product to charge not just car batteries but any battery under 110 amps. The CTEK MXS 5.0 can charge batteries up to 110 amps and takes about 35 hours to charge a 110ah battery.

This automatic battery charger is programmed to tend batteries once they’ve reached full charge. It features built-in temperature sensors that adjust the voltage output based on temperature conditions.
This small battery charger has an extremely long five-year warranty. Perhaps our favorite feature is the LCD screen, which can even provide an estimate of your vehicle’s battery charge. This voltage stayed consistent throughout. The voltage tested at 13 amps while the battery charger was in use, which is in the ideal range for a 12-volt car battery. The device’s computer automatically detects the proper voltage, so all you need to do is attach the SC1280 and press the start button. The power cord is also fairly long, making it easy to set up to SC1280. The alligator clamps are a good size with long cables and therefore easy to use. The clamps are permanently attached to the device, which is designed such that the clamps are easily wrapped and stored. There’s nothing included with the Schumacher SC1280 other than an instruction manual.
