Monsters on a Mission: A WOW Story!


What away to start out a testimonial letter, but that’s what is WOW!

Monsters on a Mission
have been fortunate to be able to use, Kinetik batteries and CTEK battery chargers for a few years, with absolute perfection with both products.  We have put these two products through more punishment in one weekend than most will do in a life time.

A brief description of Monsters on a Mission, we are a faith biased monster truck team with five monster trucks need I say more about normal wear and tear, ok I will.  Our trucks weight 10,000 lbs, have 1200-1400 horse power blown and injected methanol motors, the speed 0 to 60 is 2.2 seconds, but here is the big one “can jump 30 feet in a blink of an eye”. A 10,000 lb truck constantly jumping, landing, and pounding these incredible products. (more…)

Modern Battery Problems: Calcium/Calcium Premature End-of-Life

Batteries constantly improve, perform better and last longer. The 2010 BCI (Batteries Council International) study about “Failure modes from batteries removed from service” showed that since 1962 the average battery life has increased steadily, gaining about 11 days every year! This increased battery life has been utilized by battery manufacturers to increase the warranty.

This improved battery life has been achieved during the same time when battery maintenance for daily used cars is almost eliminated. Watering is history. The terminals are not affected by acid as in the past. What a hidden Success Story!
Anything that darkens the picture? Unfortunately, yes. The modern batteries are more sensitive to abuse, which affects the return rate. A recent study in Germany show that batteries returned simply because they are drained and difficult to recharge properly have increased dramatically.


The reasons for this increase are partly due to the car, partly due to the battery itself. The use of electronics in a modern car is sky-rocketing. The engineers call it “parasitic load” and it could be as harmful as it sounds. Leave your unattended for ten days at the airport, and you risk hearing just a “click” sound instead of your engine running. Batteries are therefore more often deep discharged than they were before the cars turned out to be your most expensive computer!
The other reason is inside the battery. The low water loss has been achieved by reducing the gassing through replacing the Antimony in the grid with Calcium. These so called Calcium/Calcium are great from most aspects. The water loss is reduced by more than 80%. The self discharge is reduced, which extends the shelf life in a store. Unfortunately they dislike being deep discharged.
The problem with Calcium/Calcium occurs when they are deep discharged. The reduced water loss on these batteries is gained by reducing the gassing during recharge. Unfortunately this gassing helps to mix the acid. As a result the Calcium/Calcium batteries very often experience stratification, i.e. uneven acid weight height wise. The acid weight could be 1.17 or lower at the top and 1.35 or higher in the bottom for a battery that seems fully charged. This could cause sulphation and grid corrosion, which leads to underused capacity and premature end-of-life.
The larger CTEK models have a unique RECOND mode for these batteries. The battery is fully charged with a normal charge cycle. After that the RECOND step kicks in, where:

1. The voltage is increased to 15.8V to get gassing and therefore mixing of the acid.
2. The current is decreased to control the gassing.
3. The time is computer controlled to 4h if the battery started as being deep discharged, otherwise 30 minutes.

This unique method reduces or eliminates the typical Calcium/Calcium stratification problem.

6 Easy Steps to Change a Battery with a CTEK Comfort Connect

1. Having a CTEK Comfort Connect connected to your battery all the time simplifies normal charging and also makes the battery replacement easy.

2. Connect a CTEK Smarter Charger with Supply Mode to the Comfort Connect and set the Mode to Supply.

3. The battery cables can now be removed. The CTEK charger keeps the electrical system alive.

4. The old battery can now be removed and the new installed.

5. Connect the battery cables. Keep the charger connected at all times.  It is always good for the battery to be fully charged before it is used. If possible, keep the charger on for a few hours.

6. You’re All Done! Keep the Comfort Connect with the protective cap on for future use.

Small can also be GREAT!

Our VP of Business Development got the following mail from a –definitely now- “CTEK fan” and I really wanted to share it with all people considering charging options or those having doubts about the differences between quality and cheap chargers.

Hi Börje,

As you probably know, I´m a “great fan” of CTEK chargers.

Recently, my Jaguar XJ6 stood unused for 5 weeks.

The battery was completely dead and then I discovered that the battery had frozen and the sides had expanded about 6-7mm on each side.

I got the battery inside (74Ah) into the warmth and I connected my CTEK charger (the smallest model). After 24h the battery “woke up”, 9V!, after 72 hours 12,3V, after 96 hours, 12,8V and after 144 hours it was charged with 14,6V.

After that I reinstalled the battery in the car and let it be until next day.

The engine got going after the first try!

Next day, the same thing, despite being so cold, -10o C.

CTEK saved my battery!

Best regards and Merry Christmas and a Happy New Year!


(Carl Holgersson from Sollentuna, Stockholm)

That is what really makes us proud, being able to solve real battery related problems

“Toaster” Battery Chargers…BAD. CTEK Smarter Battery Chargers…Good!

If you drive a car you’ve probably been introduced to battery chargers, but did you know that common “trickle chargers” or “toaster chargers” can cause more harm to your battery than good if used incorrectly.

“A trickle charger works by charging your battery at a rate similar to the rate at which it discharges. However, it is possible to cause damage to your battery by leaving it on the charger for too long. While a trickle charger works at a much slower rate than a regular battery charger, they are not designed to be left on a battery indefinitely. Depending on how depleted your battery’s charge is, you may need to leave it on the trickle charger for a few hours or for a day or two. It is important to monitor the battery while it is on the charger and remove it immediately upon receiving a full charge. Otherwise, the battery could be ruined or even catch fire.” – eHow

With a CTEK Smarter Battery Charger the issue of overcharging your battery is much less likely because of CTEK’s smart technology.  A CTEK Smarter Battery Charger monitors whether or not your battery needs more charging.  The charger can be left on as long as you like becuase it knows when to give your battery more juice and when not to.  Also, the desulphation function, that each CTEK Smarter Battery Charger comes equipped with, can extend the life of your current battery 2-3 times that of its normal life because it reconditions.

So the choice is yours.  You could sit around and wait for your battery to charge and make sure to take off your “trickle charger” or “toaster charger” so you don’t damage your battery and so it doesn’t catch fire, or you could use a CTEK Smarter Battery Charger and set it and forget it.

Never Lie To Your Parents…!: I’m in BIG trouble!!

As part of CTEK’s Smarter Battery Charger Dead Battery Story Contest we are highlighting several of the stories that were submitted over the last few months. Come back and visit our blog to read other great stories and check out our Facebook page to join our community and learn of other contests and events.

I’m in BIG trouble!!

“Ok so I was 15 years old and it was New Years Eve I had stayed out all night with some friends and my boyfriend. Of course my parents knew nothing about the party or the boyfriend being with me. So I get a call early the next day from a friend telling me I better get home that my parents found out where I was and are extremely mad!! So Im a little scared now, I call home and try to (lie) my way out of it, but my dad was not buying it. He told me I had 30 min. to get home or he was coming after me.

So we jump up, clear across town and all pile up in the car to take me home. Uh Oh the car wont start. No way!! We get a jump after 30 min. of searching and head to the nearest Kmart to get a battery, Needless to say It took 2 hours to get the battery, replace it with the old one and get me home. My dad comes running out of the house ready to whoop some You know what!! I was grounded for 6 months!!! Unreal. Wow those were the times.”

Parents always know ….
