Buying Guide

What Do You Expect From Your Products?

This question leads to 2 other small questions. The first one is “what do you expect from your car,” and the other is “what do you expect from the charger.”

How you use your car or truck can guide you to the type of suitable charger. If your car consumes a lot of electricity, especially when it’s turned off, it’s best to have your battery periodically serviced.

What Are Things Considered To Be Electrical Components?

Electrical components are everything that does not depend on an engine’s operation.

The exterior and interior lights use batteries; the same applies to the radio and any charging port in the car. Smart car systems such as GPS and cam control belong to electrical components.

If you are only concerned with improving the quality of deep cycle batteries in a vehicle you use frequently, the maintenance functions will be the best value.

If you want to maintain the quality for seasonal or occasional use, CTEK batteries are the right choice.

What Should You Do If You Use A Charger The First Time?

The charger is not too difficult to use; you won’t even have to open your hood to charge your battery. But it’s best for novices to choose a smart charger because you will never run into the risk of getting it wrong with this charger type.

All you need to do is press the mode button to select the charger into the battery and let the sensors work automatically.

For a first-time charger, you’ll want to use one with reverse polarity protection. The spark clamp and protection against overvoltage and overload are also extremely useful.

You should also review the user guide to know the features and ways to use the charger to reach its full capacity. It’s especially important to know where the mode button is.

How To Prolong The Battery’s Life?

To prolong the lifespan, you must regularly fully charge it. Moreover, the battery’s stored energy will also be significantly affected every time you start your car. It loses its charge after a period of use.

Regular drivers have no trouble keeping their cars or truck fully charged. However, long periods of use can cause lead sulfate to build up in the battery.

So when the lights dim, the car starts slowly (the symptoms of battery run out); you can use a CTEK charger to take the battery back to its normal state without opening the hood.

Is A High-Performance Vehicle Necessary?

High-efficiency automotive batteries are typical of high-capacity, providing more energy than conventional 12V lead-acid batteries. This fact requires you to have a correspondingly powerful charger like the CTEK MXS 5.0 cigarette lighter.


Can CTEK Chargers Be Used For Motorcycle Chargers?

Yes. As long as your motorcycle battery capacity is at a 12V charger. It’s best to check your motorcycle batteries to avoid deep cycle batteries and motorcycle damage.

Does Charging CTEK Need To Start The Battery Type?

No. You only need a jump starter. You find the right mode button to jumpstart the battery. Because a clean CTEK can restore a fully charged dead battery, but this will take some time.

However, regularly starting up batteries can damage chargers and shorten their life. We recommend buying a separate jump starter.

Do CTEK Batteries Need Accessories?

CTEK chargers come with all the necessary accessories and safety features, but you can find other accessories included, depending on your purpose and needs in a period.

Does The CTEK Charger Fix Layer?

Stratification occurs when the acid inside the cell separates from the water, and it only takes place during battery depletion.

The best way to avoid this is to keep the battery fully charged. And the CTEK powerful chargers can help you do that. However, in some reluctant cases, you will most likely have to buy a new battery.

The Bottom Lines

The CTEK’s 5 charger manufacturers introduced above are all the best CTEK battery chargers and are well embraced by most customers.

However, depending on your needs and purposes, you may need different chargers and a separate jump starter. Contact CTEK’s sales staff for more advice on the most suitable product, sizes, manual, maintenance of batteries, and voltage.

No matter which model you choose, CTEK is a reliable partner that helps maintain longevity and durability. You only need to spend a small investment for greater benefits in the long run.
