Many of us now own multiple vehicles, each with a battery, and this is why it’s essential to find the best trickle charger for your situation. From your daily use car to maybe a motorcycle, a jet ski, or an ATV. Some of these vehicles may only get used occasionally and sit in the garage the rest of the time.

Being left unattended for long periods can be extremely bad for a battery, shortening its working life and often failing when you need it most! To keep your batteries in top condition, always use the best trickle charger you can find. In this review, there are three trickle chargers from well-known manufacturers.

Schumacher SC1343 vs. Battery Tender Plus vs. NOCO Genius2: What Are Similarities?

As the three trickle chargers on test all keep your battery at its optimum charge level, they all have some features in common.

Battery Type: Lead-acid-type

The most common battery type in use on vehicles is the lead-acid battery and variants of it. All of these trickle chargers will work with lead-acid-type batteries.

Automatic Charging

We all prefer convenience these days, and that’s just what you get with these trickle chargers. All three have built-in automatic charging functions, you connect the battery, and the charger does the rest.

Safety Features

Good safety features are standard across most battery chargers, and the three on review are no exception. All include reverse polarity and overcharging protection as standard.

Quick-connect Cable

Some batteries are difficult to reach, which means you may forget about them. A quick-connect cable comes with all the trickle chargers on test and means you are far more likely to keep the battery in good condition.

Schumacher SC1343 vs. Battery Tender Plus vs. Noco Genius2: Key Differences Explained

Having discussed the similarities between the three trickle chargers on the test, it’s essential to look at the differences so you can choose between them.

Features and Functions

Battery Type

All the chargers work with lead-acid batteries, but a significant advantage of the NOCO Genius2 is that it also works with modern lithium batteries. As more vehicle manufacturers fit lithium batteries as standard, this feature will become necessary.

Charge Large Vehicle Batteries

With its 2A charging output, the NOCO Genius2 can maintain larger batteries and also charge car batteries. In comparison, the other two trickle chargers here are only suitable for charging smaller batteries.

Battery Voltage

Although used less often, some small engine vehicles still use 6 volt electrical systems. The Schumacher and the NOCO models will charge 6-volt batteries, while the more expensive Battery Tender cannot.

Design

The Schumacher and Battery Tender have very basic designs, with very little apart from a charging light shown on the front panel. In comparison, the NOCO Genius2 shows the charge level through four LEDs, indicates the type of battery being charged, and has a mode button on the front panel.

Supported Vehicles Models/Makes

Only the NOCO Genius2, with its higher 2 amperes output, can charge and maintain car, motorhome, and other larger vehicle batteries. The Schumacher and Battery Tender models can charge smaller batteries but only maintain larger batteries.

Additional Features

Thermal Compensation

The outside temperature where you are charging your battery can affect the charge rate and the final charge state of your battery. The Schumacher is the only model here that does not offer thermal compensation, so consider this factor if your area has extreme temperatures.

Battery Detection

All the trickle chargers on the test are fully automatic and detect the battery connected. For example, the Schumacher will detect a battery with as little as 0.2 volts charge, while the NOCO will detect a battery with just 1 volt.

Unfortunately, the Battery Tender Plus doesn’t have this feature, so it cannot charge very flat batteries. An additional feature of the NOCO is the override button, which will force the charger to charge a battery with zero volts charge.

Desulfation Mode

Only the Schumacher includes a dedicated desulfation mode, which it switches to automatically if a sulfated battery is detected.

Price, Warranty

The Schumacher is the cheapest trickle charger here, at around $35, but it offers many features included with the others despite this. NOCO’s Genius2 is the mid-priced option at about $50 and provides the most features.

Unfortunately, the Battery Tender Plus looks very expensive in this company, at just below the $100 mark, and it is hard to justify the price against the others.

Both the Schumacher and the Battery Tender have 5-year warranties, while buyers of the NOCO will have to make do with only a 3-year warranty.

No, trickle chargers are designed primarily to maintain your battery at the optimum charge. However, in this test, the Schumacher SC1343 does have sulfation detection and an automatic desulfation mode.

Are Trickle Chargers Good For Recovering Very Flat Batteries?

The answer to this depends on the model of the trickle charger. In this test, both the Schumacher and the NOCO are designed to recover very flat batteries.

How Long Does It Take To Charge A Battery Fully?

The charging time for a battery will depend on many factors, such as the current voltage level of the battery, the amperage of the battery, if it is sulfated, the outside temperature, and how old the battery is.

A flat battery can take many hours or even days to fully charge with a trickle charger, but most chargers have indicators on the front panel to show when charging is complete.

If I Unplug The Charger, Do I Need To Disconnect It From The Battery?
