What Is the Schumacher SC1359?
The Schumacher SC1359 is a consumer battery charger and maintainer for common 6V and 12V batteries. It sits in the practical home-garage category, not the professional shop category, because it focuses on automatic charging, simple controls, portability, and battery maintenance.
Its main strength is the mix of 15A rapid charging for 12V batteries and 3A charge/maintain support for smaller batteries. That makes it useful when you need to charge a car battery faster than a basic trickle charger, but still want a maintainer for seasonal equipment.
The 3.59 lb body and 10.5 x 3.63 x 7.75 in size make it easy to carry between a garage, driveway, shed, or boat storage area. The digital display, LED indicators, push-button controls, and color-coded non-sparking clamps help you set it up without guessing through a confusing control panel.

Key Features of the Schumacher SC1359 Charger
The Schumacher SC1359 gives you automatic charging for 6V and 12V batteries. Auto voltage detection helps the charger identify the connected battery voltage, which reduces setup errors when you move between smaller 6V batteries and larger 12V automotive batteries.
The 15A rapid charge mode targets larger 12V batteries used in cars, trucks, SUVs, boats, and RVs. A 15A charger will not act like a jump starter, but it can restore a discharged battery much faster than a low-amp maintainer when the battery can still accept a charge.
The 3A charge/maintain mode gives you a better fit for motorcycles, lawn tractors, and storage batteries. Float mode monitoring helps maintain the battery after charging, so you can keep a seasonal battery ready without constantly starting and stopping the charger yourself.
The charger also includes reverse hook-up protection. That feature stops operation when the clamps connect to the wrong battery terminals, which matters if you use the charger in a dim garage or help someone who has little battery-charging experience.

Who It’s For and Who Should Skip It
Who It’s For
- You own a car, SUV, truck, boat, RV, motorcycle, lawn tractor, or power sport battery and want one charger for common 6V and 12V batteries.
- You want automatic charging with multi-stage charging, float mode monitoring, auto voltage detection, and reverse hook-up protection.
- You need a lightweight 3.59 lb charger that moves easily between your garage, driveway, shed, or storage area.
Who Should Skip It
- You need to charge lithium or LiFePO4 batteries, since the SC1359 lists support for standard, AGM, gel, and deep-cycle batteries instead.
- You need an engine-start charger or booster pack, because the SC1359 is a charger and maintainer, not a jump starter.
- You want a heavy-duty professional charger for a repair shop, fleet garage, or constant daily commercial use.
How Fast Does the SC1359 Charge?
The SC1359’s fastest mode is its 15A 12V rapid charge mode. That output makes the most sense for larger lead-acid batteries in cars, trucks, SUVs, boats, and RVs, especially when the battery has enough health left to accept a normal charge.
The Schumacher SC1359 works best when you need automatic charging and maintenance, not emergency jump-start power.
The 3A charge/maintain mode suits smaller batteries and long-term battery care. You can use that lower mode for motorcycles, lawn tractors, and seasonal batteries where slower charging and maintenance matter more than speed.
The official output specification also lists 6V/2A and 12V/15A. That means the charger treats 6V batteries more gently, while 12V automotive batteries get the higher-current charge path when conditions allow it.
Charge time still depends on battery size, battery age, temperature, and how deeply the battery has discharged. A deeply discharged or damaged battery may charge slowly, fail to hold a charge, or need replacement even when the charger works correctly.

Design and Build Quality
The SC1359 has a compact body that measures 10.5 in wide, 3.63 in deep, and 7.75 in high. That size helps you store it on a garage shelf, carry it to a vehicle, or keep it with seasonal equipment without using much space.
At 3.59 lb, it feels light enough for regular home use. That low weight helps if you need to carry it from a garage to a driveway, boat, RV, or shed, but it also means you should not expect the same rugged heft as a large metal shop charger.
The digital display and LED indicators make charging status easier to read than a basic analog dial. Push-button controls also help you avoid turning a mechanical selector to the wrong mode.
Charging Technology and Battery Compatibility
The SC1359 uses multi-stage charging to manage the charging process. Multi-stage charging matters because a battery needs different treatment during bulk charging, absorption, and maintenance.
Auto voltage detection helps when you connect the charger to either a 6V or 12V battery. You still need to connect the clamps correctly and follow the manual, but automatic detection reduces one common setup mistake.
Battery compatibility is one of this charger’s strongest points for common home and vehicle use. The SC1359 supports standard, AGM, gel, and deep-cycle batteries, so it can handle many car, truck, marine, RV, lawn tractor, motorcycle, and power sport applications.
Lithium support is the main limitation. If you use lithium or LiFePO4 batteries, choose a charger that clearly lists lithium compatibility and matches your battery maker’s charging instructions.
Safety and Ease of Use
The SC1359 includes reverse hook-up protection. This feature prevents the charger from operating when the clamps connect to the wrong terminals, which helps protect the charger and the battery from a simple user error.
The color-coded non-sparking clamps also make setup easier. Red and black clamp colors give you a clear visual guide, while non-sparking clamp design adds another safety layer during connection.
You should still use the charger in a well-ventilated space and follow the manual. Lead-acid batteries can release gas during charging, so airflow matters even when the charger includes automatic safety features.
How It Performs in Real Use
For a Car or Truck Battery
The 15A 12V rapid charge mode gives you the SC1359’s best use case. When your car, SUV, or truck battery has drained but still holds a charge, the higher current can bring it back faster than a 1A or 2A maintainer.
For Motorcycles and Lawn Tractors
The 3A charge/maintain mode works better for smaller batteries used in motorcycles, lawn tractors, and similar equipment. You get a slower, more controlled mode that helps with maintenance during off-season storage.
For Marine and RV Batteries
The SC1359 supports deep-cycle batteries, which makes it useful for many marine and RV battery setups. You should maintain marine batteries on shore and match the charger settings to the battery type before starting a charge cycle.
For Seasonal Storage
Float mode monitoring helps when you store a battery for weeks or months. Instead of leaving a basic charger connected and risking overcharging, you get automatic maintenance designed to keep a healthy battery closer to ready condition.
User Feedback on the SC1359 Charger
User feedback often focuses on the charger’s simple controls, light weight, and easy-to-read display. Those points match the SC1359’s 3.59 lb weight, digital display, LED indicators, and push-button operation.
You may also see buyers praise the 15A rapid charge mode because it feels more useful than a basic trickle charger for larger vehicle batteries. That strength matters most when you need to restore a weak 12V battery and do not want to wait through a very low-amp charge cycle.
The most realistic tradeoff is durability expectation. The SC1359 is a compact consumer charger, so you should treat it as a home-garage tool rather than a rugged commercial charger for daily shop abuse.
Pros and Cons
Pros
- 15A 12V rapid charge mode suits larger car, truck, SUV, boat, and RV batteries.
- 3A charge/maintain mode helps with motorcycles, lawn tractors, and seasonal battery care.
- Supports 6V and 12V standard, AGM, gel, and deep-cycle batteries.
- Automatic voltage detection, multi-stage charging, and float mode monitoring reduce manual setup work.
- 3.59 lb weight and compact dimensions make it easy to carry and store.
Cons
- Does not list lithium battery support, so it is not the right pick for LiFePO4 battery setups.
- No engine-start function, so you cannot use it as an emergency jump starter.
- The lightweight consumer build may not satisfy you if you need a heavy-duty shop charger.
Is It Worth the Price?
The Schumacher SC1359 offers strong value for the price if you need one charger for several common battery types. You get 6V and 12V support, 15A rapid charging, 3A maintenance, AGM and deep-cycle compatibility, a digital display, and important safety features in one compact unit.
It makes the most sense if you own more than one battery-powered vehicle or seasonal machine. A car, motorcycle, lawn tractor, boat, and RV can all create battery-maintenance needs, so one flexible charger can save you from buying several narrower tools.
You should not buy it for lithium batteries, engine starting, or professional daily shop work. In those cases, a lithium-compatible smart charger, a jump starter, or a heavier commercial charger will give you a better fit.
How It Compares to Alternatives
If you want lithium support and a 10A smart charger, the NOCO GENIUS10 is a stronger alternative because it supports 6V and 12V charging and includes lithium charging modes. The tradeoff is that it gives you lower 10A charging current than the SC1359’s 15A 12V rapid charge mode.
If you want to stay inside Schumacher’s lineup, the Schumacher SC1280 is another 15A option with a broader feature set on some listings, while the Schumacher SC1360 offers a similar 15A charger-maintainer approach for power sport, automotive, and marine batteries. The SC1359 remains a smart buy when you want a simple, compact, fully automatic 15A charger with common battery support.
Where to Buy the SC1359 Charger
You can look for the Schumacher SC1359 through Amazon, Schumacher Electric’s authorized seller listings, and automotive retailers that carry battery chargers. Amazon is the easiest option when you want to compare seller details, delivery options, and buyer feedback in one place.
- Amazon: Best for quick product checks, seller options, and customer feedback.
