Maintaining battery charge levels is essential to battery performance

While a healthy battery is probably something the average person doesn’t think about very much, it can be quite a headache when a battery becomes problematic. Maintaining your battery’s charge is one of the simplest ways to ensure that it lasts as long as possible and performs optimally. 

Poorly maintained charge levels contribute to a host of issues that can compromise your battery’s lifespan and functioning. While they may not always be noticeable at first, problems may begin to pile up. Ultimately, years of battery life could be lost. 

When a lead-acid battery’s charge levels drop too low, it begins to experience sulphation. This is where sulphate crystals build up on the lead plates, leading to a drop in capacity. Sulphation can cause permanent damage, and it could necessitate that a battery be replaced. 

Lead-acid batteries that are not frequently used and maintained can also develop stratification, where the acid and water in the battery fluid separate, leading to the acid settling at the bottom. This can make sulphation worse, and also cause the plates at the top of the battery to corrode. 

These are just some examples of what can happen when a battery is damaged due to a poor charging routine. Fortunately, an intelligent charger such as the MXS 5.0 can reverse some of this damage. 

Ultimately, keeping to a regular charging schedule with a reliable charger is the best way to go. Not only will this save you money on replacement costs, it will also save you the time of having to come to your battery’s rescue in a crisis. 

A good quality smart charger is able to detect a battery’s state of charge and charge it to the optimal level for its chemistry. A charger with different modes, such as the MXS 5.0, allows you to make sure that it is on the correct setting for your battery’s technology. 

Here is some important advice from CTEK on charging your battery correctly: 

Using a Reliable Battery Charger 

A reliable charger will deliver consistent results, allowing you to charge your battery without the worry of defects, power surges, or other electrical problems.

Having a Sound Charging Routine

Charging your battery at least once a month helps get the best out of a battery and prolongs its life. 

Undergoing Simple, Regular Care

Invest in a charger with built-in functionality for both maintenance and troubleshooting to ensure your battery is functioning at its optimal capacity. 

Being Mindful Of the Weather

Be aware of the effect of extreme weather conditions on your battery, and look out for any signs of change in its performance. 

Using the Correct Charging Procedure

The only real way to restore a drained battery is to use a charger. Most other common ways work temporarily but are not dependable ways to fully recharge a battery.

The CTEK MXS 5.0 battery charging process

View the step-by-step charging process of the CTEK MXS 5.0 below:


Sulphation is one of the leading causes of damage to lead-acid batteries. A pulsing voltage removes sulphate deposits from the lead plates of the battery, restoring its capacity. 


The device now tests if the battery can accept charge by performing a soft start. If no issues are detected, the charging process will begin. 


The battery is charged with the maximum current until it reaches approximately 80% of its battery capacity.


A declining current is now used to bring the charge up to 100% of the battery’s capacity.


At this stage, the device tests if the battery can hold charge. Batteries unable to hold a charge may need to be replaced.


If a battery has been deeply discharged, a full absorption charge at a higher voltage will be performed to equalise or overcharge the battery. 


A constant voltage charge is used to maintain the battery voltage at maximum level.


The battery is maintained at 95–100% capacity. The charger monitors the battery voltage and gives a pulse of voltage when needed to keep the battery in its fully charged state.

This powerful lead-acid automotive battery charger is a must-have for any vehicle owner.
