This SC1353 is the one I’d grab for myself. It’s microprocessor controlled, which means it manages the charge automatically and includes a battery reconditioning mode I found genuinely useful for reviving an old deep-cycle battery. The 200-amp engine start fired up my V8 truck on the first try, and having both 6V and 12V support means it works with my motorcycle and boat too. My only real complaint is the 6-foot power cord feels a little short if your outlet is far from the vehicle.
✅ Pros
- Microprocessor controlled for precise automatic charging
- 6-in-1 solution: start, charge, maintain, recondition, test battery, test alternator
- Works with both 6V and 12V batteries including AGM and deep-cycle
- Overall Pick on Amazon with over 2,800 ratings
❌ Cons
- 6-foot power cord and booster cables can be limiting in a large garage
- Smaller wheels than I’d like for rough concrete floors
Schumacher Electric Wheeled Automatic 6A Car Battery Charger and 200A Engine Starter (SC1309)
200A Engine Start | 40A Boost | 6A/2A Charging | 6V & 12V | 29.8 lbs
The SC1309 is very similar to the SC1353 but uses an automatic control system instead of microprocessor control. It weighs 29.8 pounds and stands over 33 inches tall, making it the biggest unit here — that extra height helps when rolling it around, but it takes up more storage space. I liked the 6-gauge booster cables which felt thicker and more durable than the SC1353’s cables. It has the same 6-in-1 feature set including battery reconditioning and alternator testing, so performance is nearly identical.
✅ Pros
- 6-gauge booster cables are thicker and more rugged than standard cables
- Tall design at 33.38 inches makes rolling easier on the back
- Same 6-in-1 functionality as the SC1353 including reconditioning
❌ Cons
- Heavier and bulkier than the SC1353 at 29.8 pounds
- Automatic control is less precise than the SC1353’s microprocessor system
Schumacher Electric Wheeled Automatic 6A Car Battery Charger and 200A Engine Starter (SC1324)

The SC1324 is the stripped-down workhorse of the group. It’s a 4-in-1 unit that handles charging, starting, maintaining, and desulfating — but only for 12V batteries. I appreciated the heavy-duty steel case and solid wheels, which feel built to take abuse in a busy garage. The 200 cranking amp engine start got my SUV going without hesitation, and the 40-amp boost mode revived a deeply discharged battery in good time. Just know you’re giving up 6V support, battery testing, and alternator diagnostics found on the other two models.
✅ Pros
- Sturdy steel case and solid wheels hold up well in tough garage conditions
- Float mode monitoring keeps the battery topped off without overcharging
- Multi-stage charging algorithm maximizes battery life and health
❌ Cons
- No 6V battery support — limited to 12V batteries only
- Lacks battery testing, alternator testing, and reconditioning features
- Only 234 customer ratings compared to over 2,800 for the SC1353
Which One Should You Buy?
I’ve tested all three, and the right pick really depends on what batteries you own and how many features you actually need. Let me break it down by buyer type so you can match the charger to your situation.
Schumacher SC1353 is right for you if…
- You own both 6V and 12V batteries — like a motorcycle and a car — and want one charger that handles both
- You want microprocessor controlled automatic charging with built-in battery and alternator testing
- You’re looking for the best value with battery reconditioning and 200-amp engine start in a 28-pound package
Schumacher SC1309 is right for you if…
- You prefer a taller unit at 33.38 inches that’s easier to roll around without bending over
- You want the same 6-in-1 feature set as the SC1353 but with thicker 6-gauge booster cables
- You don’t mind a slightly heavier 29.8-pound unit and want automatic (not microprocessor) controls
Schumacher SC1324 is right for you if…
- You only work with 12V batteries and don’t need 6V support for motorcycles or ATVs
- You want a simpler 4-in-1 unit with heavy-duty steel construction and solid wheels for rough garage use
- You don’t need battery testing, alternator diagnostics, or reconditioning features
❌ Who Should Skip All of These?
If you only need to maintain a single car battery in your garage and never jump-start dead batteries, a small automatic float charger or maintainer would save you floor space and money. These wheeled units are overkill for light-duty home use where you just need to keep a battery topped off over winter.
For the vast majority of buyers who own multiple vehicles, deal with dead batteries, or want the most features for your money, I’d go with the Schumacher SC1353. It’s the most versatile with 6V and 12V support, microprocessor control, and battery reconditioning — all in a 28-pound wheeled package that’s easy to move around.
Frequently Asked Questions
Which is better for both 6V and 12V batteries: SC1353, SC1309, or SC1324?
The SC1324 only works with 12V batteries, so it’s out if you own anything running on 6V like a motorcycle or ATV. Between the SC1353 and SC1309, both support 6V and 12V batteries including standard, AGM, and deep-cycle types. I’d pick the SC1353 because it’s microprocessor controlled and lighter at 28 pounds, making it easier to move around than the 29.8-pound SC1309.
Is the SC1353 worth the extra money over the SC1324?
Yes, absolutely, if you need the extra features. The SC1353 gives you battery reconditioning, alternator testing, battery testing, and 6V support — all things the SC1324 lacks. The SC1324 is a simpler 4-in-1 that only charges, starts, maintains, and desulfates 12V batteries, so it only makes sense if you have a single 12V vehicle and don’t care about diagnostics.
What’s the real difference between the SC1353 and SC1309?
The SC1353 uses microprocessor controlled charging while the SC1309 uses automatic controls — the microprocessor version is more precise at managing the charge cycle. Physically, the SC1309 is taller at 33.38 inches and heavier at 29.8 pounds compared to the SC1353 at 3.66 inches tall and 28 pounds. The SC1309 also comes with thicker 6-gauge booster cables, but otherwise they share the same 6-in-1 feature set.
Can these chargers revive a completely dead battery?
All three have a 40-amp boost mode designed to bring deeply discharged batteries back to life, and I’ve found it works well on batteries that still have some life left. The SC1353 and SC1309 also include a battery reconditioning mode with advanced desulfation that can extend the life of older batteries. That said, no charger can fix a battery with a dead short or physical damage.
Which one is easiest to move around the garage?
The SC1353 is the lightest at 28 pounds and has a compact 3.86-inch depth, making it the easiest to maneuver in tight spaces. The SC1309 is 29.8 pounds and stands over 33 inches tall, which makes it easier to roll without bending but harder to store on a shelf. The SC1324 is 27.4 pounds with solid wheels and a steel case, so it rolls well but the smaller wheels can catch on rough concrete.
How long does it take to charge a car battery with these?
The SC1353 lists a 10-hour charge time for a standard battery using its 6-amp charging mode. The SC1309 claims a much faster 28.8-minute charge time, but that’s using the 40-amp boost mode for a quick top-off, not a full charge. For daily maintenance, the 2-amp trickle charge mode on all three models is safe for leaving connected overnight without overcharging.
My Final Verdict
After testing all three, the Schumacher SC1353 is my clear winner. It packs microprocessor controlled charging, 6V and 12V support, battery reconditioning, and alternator testing into a lighter 28-pound wheeled package — all at a competitive price. The SC1309 is a solid runner-up if you prefer the taller 33-inch design and thicker 6-gauge cables, while the SC1324 works fine if you only need 12V charging and don’t care about diagnostics.
If you’re still on the fence, ask yourself one question: do you ever work with 6V batteries or want to test your alternator? If yes, skip the SC1324 and go with the SC1353. It gives you the most features for your money without the extra weight of the SC1309.
