Here at Schumacher Battery Charger, we see a lot chargers.

Most of them do the job as promised, so we write up a review, list the features, rate the overall experience and then move on… not reflecting too much on the experience in general.

However, every once in a while, a charger comes along that really stands head and shoulders above the rest in terms of reliability, ease of use, and customer satisfaction.

Today we are writing about one of those chargers:  The Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger

Although there are a few other Schumacher Battery Chargers that we like a little more, such as the Schumacher SE-4022 (we love that charger), the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger ended up winning the Consumer’s Choice Award for both advanced features and affordable price.

Note:  Although the Schumacher SE-4022 was better on raw horsepower (amperage) and longevity (due to the large internal fans and industrial-grade electrical components), it was a bit too bulky for most residential applications and wasn’t quite as “automatic” as the The Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger.

The Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger can handle just about anything you can throw at it:

  • 6 Volt Batteries
  • 12 Volt Batteries
  • Deep Cycle Batteries
  • Lead Acid Batteries
  • AGM Batteries

One of the nicest features of the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger is the fact that it helps protect you from overcharging a battery.  If you set it for 10 amps or 15 amps, you can walk away for a while and just let it do it’s thing.  When the battery is fully charged, it detects that and switches to a “maintenance mode” that feeds a small 2 amp charge to the battery to keep it charged and “topped off” until you return to disconnect the battery.

Some people have written in to tell us that the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger does not accurately detect the percent charged.  We agree.  In our testing, we have found that it overestimates the percent charged by about 5 percent.  Personally, I think that this is another safety feature disguised as a flaw, as overcharging a battery can threaten the health of both you and the battery.

The desulfation feature is nice too.  Although it doesn’t work all the time (and it’s certainly not a “cure all” for an old battery), desulfation can certainly breath new life into an old, worn out battery.  Just plug in the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger and it determines if the battery needs to be desulfated… and if so, starts the process of sending the high amp pulses necessary to break down the sulfate crystals.

Note:  Sulfation is when lead sulfate crystals form on the conductive plates on the inside of a battery.  These crystals are non-conductive and they cover the plates, these crystals slowly degrade the performance of the battery.  Sulfation is a natural process that occurs as a byproduct of the chemical reaction of lead acid batteries.  Sulfation occurs more often on batteries that go unused for long periods, such as boats (which is why the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger has this desulfation feature).

Another thing to note is that this charger is ideal for people with deep cycle batteries.  Deep cycle batteries are primarily used in:

  • Planes
  • Boats
  • Emergency Sump Pump Battery Backup Systems
  • Solar or Wind Power Battery Banks
  • Battery Powered Scooters

So, if you have any of those, the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger is probably for you.  It’s the perfect all-purpose battery charger to have around the house or garage for the occasional battery recharging.

However, the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger is not for everyone… and it is certainly not designed for those with more “advanced” charging needs.  Even though we love the Schumacher SSC-1500A Ship ‘N’ Shore SpeedCharge Charger, it’s not designed for heavy usage (such as in a fleet environment or on a farm or in a busy garage, for example).  For that, pay a little more and move up to the Schumacher SE-4022.

Selecting the Right Deep Cycle Battery Charger

Selecting the Right Deep Cycle Battery ChargerThere are several different types of batteries and battery chargers; but the two main categories are auto batteries and deep cycle batteries.
While these two batteries are very similar in construction, they differ in the way they release power.

Car batteries store and release the surge of power needed to turn over the starter and get your car running… And while running, the alternator recharges the battery so it can re-start the car later.

Deep cycle batteries are designed to release their power over a longer, more extended period of time; and they discharge more fully before accepting a recharge than regular car batteries.

The most common type of deep cycle batteries are those used for storing the energy created by solar power, those used for back up power or lighting, or batteries found in RVs, golf carts or boats.

Sometimes called “fork lift” or “traction” batteries, these deep cycle batteries are used when power is needed over an extended period of time.

And these deep cycle batteries are used because (unlike auto batteries) they have very thick, self contained plates on the interior of the battery (which is also a lot larger and heavier than a car battery) because you can get a lot of power storage into one single battery.

These larger, bulkier “fork lift” deep cycle batteries are designed to expend up to 80% of total battery capacity; but regardless of the deep cycle battery you use, you will see the best results (and longer battery life) when you recharge your battery at about a 50% discharge.

The Best Deep Cycle Battery Charger

You have multiple choices when it comes to choosing a deep cycle battery charger; and the majority of them are all “smart chargers”; which means that they are controlled by a microprocessor to monitor the charging period.

But the best deep cycle battery chargers use a “3 stage” battery charging technique. These 3 stage deep cycle battery chargers work like this…

Three Stage Deep Cycle Battery Chargers

  1. The bulk charge – The bulk charge is the first stage in the 3 stage process. Electrical current is sent to the battery at the maximum safe rate that the deep cycle battery will accept. The bulk charge continues until the battery voltage reaches between 80-90% capacity.Generally, this means that the voltages during bulk charging range anywhere from 10.5 volts up to 15 volts; though each individual battery may have a limit on the maximum current the battery (or its wiring) can handle.
  2. The absorption charge – The second stage of the 3 stage deep cycle battery charger is the absorption stage. This is where the voltage is maintained at a constant level as the current slowly tapers off since the internal resistance of the battery increases during the charging.It is at this point that the charger pumps out the maximum voltage for the deep cycle battery; generally around 14 volts to 15.5 volts.
  3. The float charge – This is third stage of the three stage deep cycle battery recharger, and it kicks in once the battery has a full charge.Once the battery has a full charge, the voltage is reduced by the charger to eliminate gassing and insure longer battery life.  This stage is often referred to as a “maintenance” or “trickle” mode, since it is primarily designed to keep a fully charged battery from losing power or discharging; and it detects fluctuations in the deep cycle battery voltages and maintains the correct charge in the battery by sending short bursts of power to the battery when it detects power discharge.

The Best Deep Cycle Battery Chargers Use 3 Stage Charging

When looking for the best deep cycle battery chargers, stick to the chargers that use the 3 stage charging techniques. It is hand free, and insures the safety of your battery.

There are a few battery chargers that use the bulk charge method only. While these chargers are fine if you need to charge a battery quickly, there is absolutely no (or very little) voltage regulation.

Using deep cycle battery chargers without any voltage regulation is a quick invitation to deep cycle battery damage; and you have to watch these chargers like a hawk to insure that you do not overcharge your deep cycle battery.

Using a 3 stage deep cycle charger not only recharges your battery as quickly as possible; but it also prevents any damage to the battery as well without having to monitor the progress of the charge.

Some of the better 3 stage chargers are made by Schumacher Electric, Xantrex as well as Iota Engineering; and can be found at multiple places online.

Matching Chargers to Battery Types

Matching Chargers to Battery TypesWhenever you are looking to charge a battery, there are a few ideas you need to consider before hooking anything up to anything else.

It is critical that you match the right battery charger to the right battery type to avoid damaging both the charger as well as the battery.

And not only that, but using the incorrect charger with the wrong battery type can also result in personal injury as well; as the battery may explode and send flying battery acid and solid parts throughout an enclosed area causing serious, permanent injury or blindness.

Battery Construction – How Batteries Work

To match the correct battery to the correct charger, let’s first examine exactly how batteries work.

Most people have no idea on how a car battery works in their car. So first we’ll go over the basic components of a lead acid battery and then show how they all work together generate electricity in your car.

Inside the battery are the basic electricity producing parts of the battery. These consist of…

  • A series of positive plates and negative plates arranged in cells (every 12 volt lead acid car battery will have six cells),
  • A liquid electrolyte solution
  • Individual battery cell separators
  • All included inside the polypropylene or hard rubber exterior casing of the battery.

The electrolyte solution is a mixture of sulfuric acid and water which conducts current through the movement of ions (charged particles in the electrolyte solution) between the positive and negative plates in each cell. It supplies sulfate ions for reaction with the active material of both positive and negative plates.

The positive and negative plates are generally rectangular components that contain the active material and a mechanical support structure called a grid (which is a lead alloy framework that supports the active material of a battery plate and conducts current by carrying electrons to and from the active material). Plates are either positive or negative, depending on the active material they hold.
So what happens is that the battery receives electrical current from the alternator as it is rotated by the fan belt. Small magnets inside a nest of copper wiring in the alternator create an electrical current which is then sent to the battery.

This electrical current flows thru the electrolyte in your battery, and the positive and negative ions are attracted to the positive and negative plates inside the battery; which stores them as electricity to run the various electrical systems in your car.

Matching the Right Battery Construction to the Right Charger

Before getting the right charger for your battery, you need to understand basic electricity. Every battery (car battery, appliance battery, dry cell batteries… even AAA batteries) have dual polarity with two poles (or posts).

One post is positive and the other negative; and it is crucial that you connect the correct polarity of the battery charger to the correct battery pole to avoid damage to either the battery or the charger.

And you need to match your battery charger with the correct battery type. For example, do NOT use a car battery charger to try and recharge a dry cell battery (like those commonly found in home appliances).

And every battery charger is designed to be used with a regular 120V AC outlet; and a grounded outlet at that.

A temporary adapter may be used, (in the USA only; not other countries like Canada), to connect this plug to a two-pole receptacle if a properly grounded outlet is not available.

When connecting your battery charger to your battery, you need to insure that the correct voltage is selected on the charger to match the voltage of the battery being recharged.

For an auto battery, this is 12V; while marine (boat) batteries can fluctuate… reaching as high as 32 V. For this reason, it is critical to not only match the polarity between battery and charger; but also the correct voltage for recharging as well.

And watch your charging time. Some of the more basic chargers do not regulate the charging current, and you will need to stop the process manually or lower the charge current to prevent “overcharging” of the battery.

More expensive battery chargers like those using the 3-step charge profile (also referred to as IUoU chargers) charge the battery fully and safely in a short amount time without requiring manual intervention.

The Right Charger for the Right Battery

Now that you understand how a battery works, you should see why it is critical to match the right charger with the right battery. It will save both the battery and the charger from any damage, and it will also eliminate the possibility of any physical harm as well.
