Keep reading to find out why I highly rate the CTEK CT5 POWERSPORT and would never have a vehicle without one.


Setting the scene

It’s a beautiful day, the sun is shining and you’re off for a ride. What is the most disappointing thing that could happen? Finding you have a flat battery!

With a CT5 POWERSPORT here’s how to:

  • never face a flat battery again
  • make your battery last considerably longer and
  • perform more reliably

Available to buy here.

Introducing the CTEK CT5 POWERSPORT providing fully automatic charging for a range of vehicles.

With lock-down, winter, injury or just life taking over seeing many motorcycles and cars parked up for prolonged periods of time keeping their battery health up is important for a few reasons:

  • ensuring the vehicle will start when you decide to use it
  • keeping the battery health up and charged to capacity
  • helping ensure longevity of the battery
  • guaranteeing your battery is ready to go when you are

Unfortunately, if left unused a battery will lose charge and when a battery loses is full charge it dramatically reduces the long-term life of the unit. The CTEK devices are designed to live on your battery when not in use. They are perfectly engineered to provide the perfect level of current to keep the battery life in the ready and happy range. It’s actually possible to keep a battery running for many years longer when properly maintained with a CTEK too. That is a big saving.

The CT5 POWERSPORT has been designed specifically to charge and maintain powersport batteries using advanced technology to give you three fully automatic charging and maintenance programs:

  • Normal
  • AGM
  • Recond


They are the leaders in the market and they’ve got years of R&D to ensure the optimum performance int heir produces. The most important property of a battery charger is that it reaches the exact voltage during the charging cycle. Ge this wrong and your battery is in trouble. If the voltage is too high, the battery boils. The battery then becomes unusable due to dried-out cells and crevice corrosion, which occur when there’s high acid concentration and overheating during charging. If the voltage is too low, you end up with an incompletely charged battery that will lose more and more capacity until it gradually becomes unusable.

CTEK have designed a range of products fit for purpose. Many times a vehicle is going to be parked outside when needing charging, leaving you at risk with the elements and electrical products. However, CTEK know battery chargers are often used in damp and dusty environments, such as:

  • Outdoors
  • In garages
  • On caravans and campers
  • Around harbours and on boats

All CTEK battery chargers are approved for outdoor use (IP65 and IP44). If you’re using a cheaper rival and you’re using a battery charger outdoors, you must use a charger that’s approved for outdoor use or you could run into trouble.

Why battery charging should be on your maintenance list

As vehicle technology continues to develop, more and more strain is placed on the battery. As a result, battery charging has become an essential part of bike and car maintenance which should be considered as important as checking tyre pressures and oil levels.

There are various types of battery charger currently available – mostly smart chargers and trickle chargers. However, smart chargers present a much safer and efficient way of maintaining and prolonging the life of the battery.

How a trickle charger works and why you don’t want one

With a trickle charger once a battery has reached its optimum charge levels, a trickle charger will simply send in a level of charge for a certain amount of time and then switch itself off. It will continually repeating the process until it is removed from the battery. This method of battery charging can potentially overcharge the battery, causing it to dry out or even start to gas, and could ultimately kill the battery.

This is why I recommend a smart charger.

How a CTEK smart charger works

CTEK’s smart chargers move into a pulse maintenance mode once the battery is fully charged. Rather than sending in a charge and estimating what the battery needs, a CTEK charger will stay in constant communication with the battery, reacting and charging only when it is needed.

In pulse maintenance mode, the battery will be allowed to naturally self discharge to a certain level before being fully charged once again. Not only does this avoid the risk of overcharging but, as the battery is being exercised as it would be during normal use, the lifespan of the battery is extended considerably.


Battery failure

If you look at the statistics, battery failure is often considered the number one cause for breakdowns around the world. This is both a big cost for possible call outs to get you home but also in the cost of new and replacement batteries due to failure from lack of maintenance.

Our modern vehicles have pretty complex and sensitive electrical equipment that constantly draws current from the battery, which means there is an ever-increasing number of mechanical faults that are battery related. The good news is that the expense and inconvenience of battery failure could be heavily reduced by regular battery maintenance.

CTEK’s unique range of smart chargers optimise the performance of lead-acid batteries through accurate readings of a battery’s charge levels, then ensuring the appropriate action is taken so the battery is always ready for use.

CTEK chargers extend the battery’s life and eliminates the problem of battery failure. More importantly, it makes sure that vehicles start first time, every time and the problem of battery failure is eliminated.

How CTEK chargers connect

Our chargers are easy to connect, spark proof and reverse polarity protected, so you can use them unsupervised and there’s no need to even disconnect it from the battery – simply ‘plug and play’ and the charger will do the rest.

What do these mean?

Normal – this is for living on your battery and maintains the correct charge to be ready for action. The units come with small battery connections that can be fitted and left discreetly on the bike. You can then clip the CTEK on and off in seconds giving you no excuses to not pop it on when you park up.

Recond – if your battery has run flat or is losing charge rapidly, the CTEK CT5 POWERSPORT can be put on an intelligent mode than will effectively recondition your battery. It’s not guaranteed to bring it back to live but I’ve many, many a battery living on after a CTEK recond.

What is the CTEK CT5 Powersport

The CT5 is a smart charger to optimise the performance of lead-acid batteries through accurate readings of a battery’s charge levels, then ensuring the appropriate action is taken so the battery is always ready for use. It effectively charges and maintains your battery when not in use.


Ease of use

Attached using two battery connections you simply install these once and you’re then good to go. You can leave it on for endless amounts of time. I’ve left my Harley for 10 months before and she started first turn over having had the CTEK CT5 POWERSPORT on to keep the battery maintained and ready for action.

Honestly, as someone who has owned a CTEK charger for over 12 years with the original unit still working, I have not found a single limitation. Having correctly maintained batteries with a CTEK unit installed on each vehicle, I would never be without them.

Maybe the limitation is on the human. If you forget to connect your CTEK you’re going to regret it….

You’re looking at £60-75 for a unit that comes with a warranty and is likely to last 10 plus years. You’ll have a ready for action bike or car and the piece of mind that you’re properly maintaining them. Avoiding the disappointment of a ‘sputter, sputter, sputter’ is worth every penny.  Also, by monitoring your battery condition, you can prevent a deep discharge occurring, which will result in loss of performance and early replacement.

See CTEK chargers on Amazon


  1. Works on all 12V batteries (lead acid) and newer models also to lithium batteries
  2. Ensures your battery is ready to go when you are
  3. Increased battery life to save you money

Tips From Experience

  • The sooner you get one the sooner you’ll keep your battery health up
  • Get in the habit of having it permanently connected when parked up, it’s designed to be so it won’t over or under charge.
  • It’s kind of magic how a totally dead battery that you thought was only destined for scrap can be fully reconditioned and live on reliably after a CT5 revamp – saves you money on battery’s.

Overall Rating

Small but highly powerful and practical device giving you the confidence that you’re ride will be ready to go when you are.
