Safety Features
Battery Tender Plus is a 1.25A charger designed to quickly charge the car battery, but it also proves to be very useful for power maintenance when the battery is not in use. The manufacturer claims that Tender Plus is way safer than most of the competition and ensures great performance without overcharging and damaging the car’s battery.

Let’s not forget that it weighs around 2 pounds and measures 11 x 4 x 11 inches so you won’t have any problems with storing it either. The box includes a 6-feet long power cord, battery tender ring terminals, and alligator clips. We would only like to see those alligator clips in a bigger size, but it’s just a minor issue!

Criteria Used in Evaluation of the Best Trickle Chargers

 

In order to rank our 10 best picks according to their quality and performance, we had to go through many factors and features and compare them all together. Only then we were able to rank them properly from 1 to 10. Here are some of the things that were crucial in the evaluation of the best trickle chargers:

Performance

Although all of our picks provide exceptional performance, which is why they made it to this list in the first place, they do differ in some additional features that influence their overall performance. For example, trickle chargers that can charge a wide range of batteries are on the top of our list because of their versatility. They are suitable for charging not only stored vehicles but also all kinds of tools and devices. Also, they all come with an impressive number of safety features for protection of your batteries, but some of them offer more features than the others, and we had to take this into account.

Design

It’s very important that trickle chargers have an intuitive design to allow for easy usage and simple charging process. We assigned additional points to all those devices that came with LED indicators and LCD screens for better readings of the battery status, long cords, adapters for easy connection, and more. All of these little things influence the user-friendly experience and make the charging process a lot easier. Additionally, we took into account the compact design, portability and all features that make the charger easier to store.

Price

Lastly, cost and value were incredibly important factors in the evaluation. Whether you can afford a pricey product or not, you want to know that you’ll get a well-performing device that will offer enough value for the money. This is especially important for the trickle chargers because they could damage the battery if they are not well made! That’s why the balance of cost and value of each product on our list were such an important factor in the evaluation.

 

Other Factors to Consider

 

Before you make up your mind and chose one of these amazing products from our list, we recommend taking a few extra steps just to make sure you’re making the right decision. Here are some factors to consider before the very purchase:

Purpose

First and foremost, you should ask yourself how do you intend to use one of these great devices. While most of them can charge and maintain battery power at the same time, they often do one mode better than the other. You should consider whether you primarily intend to use one of these devices for charging your vehicles and tools or you need a battery maintaining device for your stored equipment, cars, and motorcycles. This will significantly narrow down the options and help you choose the perfect product for your needs.

Size and Type

Don’t forget to check which type of battery you need to charge and the engine size of your vehicle! Big engines require a more powerful charger, and if you don’t check the engine size you can easily make mistake and purchase the one that can’t work on your type of vehicle. The same applies to battery types because not all chargers work on all battery types!

Performance

Do you need a fast charger or you’re satisfied with safe but slow one that can easily maintain your stored battery? How about other things such as safety features (water, dust and scratchproof design), portability, and user interface? All of these things are important when it comes to choosing the perfect trickle charger that will last for a long time and always provide flawless performance. Think wisely about the set of features you require from the product and only then you can start searching for the one that fulfills them all.

 

FAQ

Frequently Asked Questions

 

Q: Can I use any trickle charger to charge my vehicle?

A: No, they are not universal. Each one of them offers different output power and they are not suitable for all battery types. You should first check the type of battery you want to charge – you don’t want to purchase a wrong model because it can damage the battery. Also, you should check the engine size to make sure that a particular device will be able to charge it.

Q: Is it true that they could damage the battery?

A: Yes, they could damage the battery if you leave them plugged in for too long (overcharging damages the battery). However, these days most of the trickle chargers have an automatic switch from charging to float mode when your vehicle achieves full battery status. This prevents possible overcharging and keeps the battery safe no matter how long you leave the charger plugged in.

Q: How long does it take to fully charge a car battery?

A: These chargers operate at around 2 amps which means that they will take quite some time to charge your car. Most of them require around 24 hours, but this depends on the power and overall performance of the particular model. They are mostly designed to maintain battery power in the safest possible way, which is one of the reasons why they are so slow.

Q: Can I find the one that charges both cars and tools such as lawnmowers, tractors, and more?

A: Absolutely! However, don’t go for the most powerful trickle charger you can find but rather examine all the features it provides and whether it is suitable for all the batteries you have. It’s very important not to connect the battery with the wrong type of charger! Also, keep in mind that this kind of versatile charger will cost you a few more bucks.
