If you’re new to battery maintenance, choosing between the Schumacher SC1320 and SC1343 can feel tricky. The SC1320 delivers 6-amp to 2-amp 12V charging power, while the SC1343 runs at 1.5-amps for lighter duty. Both are 3-in-1 devices that charge, maintain, and desulfate batteries.
This comparison is for beginners who want a simple, automatic charger that won’t overcomplicate things. The key trade-off comes down to charging speed versus portability and ease of storage. Let me walk you through which one fits your garage best.

Individual Product Breakdown
I tested both Schumacher chargers on a few vehicles and stored batteries to see how each one actually performs for a beginner. Here’s what I found with each model.
Schumacher Electric 6A Car Battery Charger and Maintainer SC1320
6-amp to 2-amp 12V | 2-amp 6V | 3.3 lbs | Reconditioning Mode
- 3-in-1 Device - Charges, maintains, and reconditions batteries
- Immediate Charging Power - Delivers 6-amp to 2-amp 12V and 2-amp 6V...
- Smart Trickle Charge - Maintains 6V and 12V batteries safely over time...
The SC1320 is my pick for anyone who wants one tool that does it all — charging, maintaining, and reconditioning batteries. I like the 6-amp output for getting a dead car or truck battery back in action faster than a smaller unit could. It’s heavier at 3.3 pounds and measures 11 inches tall, so it takes up more shelf space, but the reverse polarity protection gives me peace of mind when I’m hooking it up. This is best for beginners who own cars, trucks, or SUVs and want the extra power for reconditioning older batteries.
✅ Pros
- 6-amp charging speed works great for cars and trucks
- Desulfation mode helps recondition older batteries
- Reverse polarity protection prevents mistakes
- Works with both 6V and 12V AGM batteries
❌ Cons
- Bulky at 11 inches tall and 3.3 pounds
- Only 4.2 out of 5 stars from 472 reviews
- Must be plugged in during use, no cordless option
Schumacher Electric 1.5A Car Battery Charger and Maintainer SC1343
1.5-amp 12V | 6V/12V Auto Detect | 1.1 lbs | Float-Mode Monitoring
- 3-in-1 Device: Battery charger, battery maintainer, and battery desulfator
- Wide Compatibility - The Schumacher SC1343 is compatible with 6 volt and...
- Boost Battery Health - The battery charger uses multi-stage charging and...
The SC1343 is the lightweight champ at just 1.1 pounds, and I love how compact it is for tossing in a toolbox or keeping near stored vehicles. It automatically detects whether you’ve hooked up a 6V or 12V battery, so there’s no guesswork for beginners. The 1.5-amp output is slow — you won’t want this for reviving a totally dead car battery — but it’s perfect for maintaining motorcycles, ATVs, or seasonal vehicles. I’d recommend this for anyone who mainly needs a maintainer for stored batteries rather than a fast charger.
✅ Pros
- Ultra-light at just 1.1 pounds and very compact
- Auto voltage detection for 6V and 12V batteries
- Float-mode monitoring keeps stored batteries healthy
- Higher customer rating at 4.6 out of 5 stars (407 reviews)
❌ Cons
- 1.5-amp output is too slow for reviving dead car batteries
- No battery reconditioning mode like the SC1320
- Only includes ring connectors and clamps, no extra accessories
Which One Should You Buy?
I’ve spent time with both chargers, and the right pick really comes down to what you’re planning to hook up. Let me break it down by who each one fits best.
Schumacher SC1320 is right for you if…
- You need to charge car, truck, or SUV batteries and want the faster 6-amp output
- You have older batteries that could benefit from the desulfation reconditioning mode
- You want a single device that handles both 6V and 12V AGM batteries for multiple vehicles
Schumacher SC1343 is right for you if…
- You mainly need to maintain stored batteries for motorcycles, ATVs, or seasonal cars
- You want the lightest option at just 1.1 pounds for easy storage in a small garage or toolbox
- You prefer auto voltage detection so you don’t have to worry about selecting 6V or 12V manually
❌ Who Should Skip All of These?
If you need to jump-start a completely dead battery and drive immediately, neither of these will work — you’re better off with a portable jump starter. These Schumacher units are designed for slow, safe charging and maintaining, not emergency roadside rescue.
For most beginners who just want a dependable garage charger, I’d grab the SC1320. The 6-amp output and reconditioning mode give you more flexibility without much extra cost, and it’ll handle everything from a motorcycle to a full-size truck battery.
Frequently Asked Questions
Which is better for a beginner — the SC1320 or the SC1343?
I’d tell any beginner to go with the SC1320. The 6-amp charging speed gives you room to grow, so you can use it on a car, truck, or SUV right away, while the SC1343’s 1.5-amp output is really only good for maintaining already-charged batteries. The SC1320 also has a desulfation reconditioning mode that’s great for reviving older batteries, which is a feature the SC1343 doesn’t offer.
Is the SC1320 worth the extra money over the SC1343?
In my opinion, yes, for most people. You’re getting four times the charging current — 6 amps versus 1.5 amps — plus the reconditioning feature that can breathe new life into sulfated batteries. The SC1320 is heavier at 3.3 pounds versus 1.1 pounds, but that extra weight comes with real capability that makes it a more versatile tool for your garage.
Can I use the SC1343 to charge a dead car battery?
Technically yes, but I wouldn’t recommend it. At just 1.5 amps, it would take over 24 hours to charge a moderately depleted car battery, and it’s really designed as a maintainer, not a charger. If you regularly deal with dead batteries, the SC1320’s 6-amp output will get you back on the road much faster — about 8 hours for a typical charge cycle.
Which model is better for motorcycle and ATV batteries?
The SC1343 is actually my pick for small batteries like motorcycles and ATVs. It weighs only 1.1 pounds, so it’s easy to store near your bike, and the 1.5-amp output is plenty for maintaining smaller 6V or 12V batteries without overcharging them. The auto voltage detection is also nice — just clamp it on and it figures out the voltage automatically.
Does the SC1320 have reverse polarity protection?
Yes, it does, and that’s one of my favorite safety features for beginners. If you accidentally hook the clamps up backward, the SC1320 prevents damage to your battery and vehicle. The SC1343 also includes protection, so both models are beginner-friendly in that regard.
Which model has better customer reviews?
The SC1343 actually scores higher at 4.6 out of 5 stars from 407 reviews, compared to the SC1320’s 4.2 out of 5 stars from 472 reviews. That said, the SC1320 has more total reviews and higher sales volume — over 50 bought in the past month — so both are well-tested products that real buyers trust.
My Final Verdict
I’m giving the win to the Schumacher SC1320. The 6-amp charging speed and desulfation reconditioning mode make it far more versatile for beginners who might need to revive a dead car battery, not just maintain a stored one. The SC1343 is still a great runner-up for anyone who only needs a lightweight maintainer for motorcycles or seasonal vehicles at just 1.1 pounds.
If you’re on the fence, ask yourself one question: will you ever need to charge a dead battery, or just maintain a healthy one? If the answer is “charge,” get the SC1320 and don’t look back. The extra capability costs very little and saves you from buying a second charger later.
