3. Pros & Cons of Cen-Tech Battery Charger


  • Safety: Safety is the number one benefit you will get from the Cen-Tech battery charger. This 12-volt charging unit has a particular set of in-built safety features that prevent potential safety issues, which may arise as a result of using the product. These include auto shutoff, reverse polarity alert, thermal protection shutoff, self-resetting circuit breaker, and spark proofing. All will ensure your battery is not susceptible to explosion and other safety issues. Subsequently, you and anybody else around the unit when it is charging a battery will be safe.
  • Works Great & Suits a Variety of Charging: Besides safety, another notable benefit of this product is that it works great and charges several types of batteries other than car batteries. The Cen-Tech car battery charger makes sure a battery receives a fixed amount of electricity, preventing overcurrent related battery damages during the charging process. Apart from that, it automatically stops charging the battery once the battery is fully charged, further preventing damage and wastage of power. Plus, it charges not only car batteries, but also many other types of batteries, including generator batteries and so on, making it a useful product for many charging applications.
  • Extends the Lifespan of Your Battery: The Cen-Tech battery charger is designed with the service life of your battery in mind. This product does not charge just for the sake of it. It resuscitates the internal components of your battery that are slowly dying, optimizes the components, and prevents charging related damages from killing them further. That extends the service life of your battery to a greater extent.
  • Engine Start: Besides built to extend the service life of your battery, the Cen-Tech heavy duty battery charger is also equipped to help you jumpstart your car when your battery is low. With the incredible engine start feature, you do not have to wait until your battery gets fully charged before you can start your engine. All you have to do is to connect the charger to your engine through your battery and then try to jumpstart the car.
  • Portable and Lightweight Design: Last but not least, the Cen-Tech automatic battery float charger for automobiles is incredibly portable and lightweight, measuring 10 cubic inches and weighing slightly above 11 pounds. That makes it easy to store in your car, secure and comfortable to travel with for battery emergencies that may arise when you are on the move.


  • A Fairly Short Warranty: The first drawback of the Cen-Tech battery charger is the type of warranty that comes with it. This product comes with a 90-day limited warranty. While the manufacturer vouches for the product, maintaining that it is free from defects in materials and quality, the fact is that a 3-month warranty is too short to sufficiently cover potential errors that may arise from a substandard. In our view, this warranty is limited, meaning it does not cover every possible defect. In our opinion, the product can do better with a more extended warranty like 12 months or so. But do not worry about that, this is one of the best quality battery chargers on the market that is not going to break as soon as you may think.
  • Must Be Charged In Advance:Another disadvantage of this battery charger, just like others, is the fact that it must be charged in advance if one is to benefit from it during a time of an emergency. If you have not charged the charger since the last time you used it and the unit is sitting somewhere in your trunk, collecting dust, it might now be of help with your drained or dead battery.In other words, it may only be convenient if charged in advance and appropriately stored before use. So, for the lazy and careless folks, this product requires some effort to impress.
  • Fairly Costlier: Last but not least, the Cen-tech charger for car batteries and other types of batteries seems to be a little bit on the high end in terms of price. That is according to what many buyers have had to say regarding this portable unit. However, as mentioned earlier, the higher the price, the higher the value of a product.

4. What Sets the Cen-Tech Battery Charger Apart?

With many alternative products that seem to cost less than the Cen-Tech manual battery charger, one may wonder what’s the point of going with the product when there are plenty of cheaper options out there. Well, this portable charging unit for your battery sets itself apart with several benefits and features you will not quickly get from other batteries. First, the Cen-Tech battery charger will optimize your battery and prolong its service life, allowing you to save a lot of money you may otherwise need to spend on a replacement battery.

Second, it will charge your battery correctly without damaging it even if you fail to pay attention to the charging process. Other chargers will damage your battery if not monitored, primarily through overcharging. Last but not least, this charging unit is safer than the rest as it is equipped with almost four dedicated safety features, including auto shut off, self-resetting circuit breaker, and more.
