Features to Consider in Good Trickle Chargers

How do trickle chargers work?

There is some pretty serious engineering behind the whole trickle charging system. The trickle chargers use electricity to replenish batteries at the same rate as the self-discharge and the energy gets transferred in a “trickle,” which explains the name of this sort of battery chargers. The trickle charging process is specific because you’re basically charging a fully charged battery to stop the discharge process which takes place when the battery’s not active for longer periods of time. So if you want to keep your vehicle’s battery in operable condition, this sort of charging is crucial. Also, the trickle charging is not only beneficial in a sense that it’s keeping your battery full as this sort of charging has a great effect on the overall battery condition and functionality.

It’s crucial that you find a high-quality trickle charger product because the trickle charging process must be done under specific and secure conditions which prevent overheating that can lead to explosions. That is why you should choose only the trickle chargers which can perform float-charging. The float-charging is also a specific charging process which gets the battery under continuous float voltage and thus prevents the battery from overcharging that leads to sudden overheating.

What is a float voltage?

Float voltage is the voltage at which a battery gets maintained after being fully charged to keep the full capacity by compensating for inevitable self-discharge process. There are two possible ways for the voltage to be kept constant. The first way is to keep the voltage constant throughout the entire duration of the cell’s activity. Such a way of keeping the voltage constant is specific for automotive batteries. The other way to keep the voltage constant is to hold the float voltage activation for a particular phase of charging by the charger. This way of keeping the voltage constant presents how the trickle chargers operate.

However, the concept of a float voltage cannot be equally applied to all sorts of battery chemistries. For example, lithium-ion cells need exceptionally cautious float-charging as they badly react to even the slightest overpowering, which means that they tend to explode or become dead if accidentally overcharged. Some batteries are less tolerant to overcharging and overheating than others, but overheating, in general, will shorten the battery life and leave permanent damage to the chemical system within the battery. So, before you buy a charger make sure that your vehicle has a battery that can be safely float charged.

Pro tips for battery storage and maintenance

A trickle charger is an immutable ally if you want to properly maintain your vehicle’s battery, but it’s of great importance that you take preliminary steps to ensure your battery’s longevity. So, if you don’t want to end up stranded in the middle of the road make sure that you carefully read the tips for battery storage and maintenance.

First, you should store your battery or vehicle in a cool location, which is protected from extreme temperatures and changes. A constant cool temperature is crucial for your vehicle’s battery as it enables the inner chemical structure to remain in a condition that allows it to remain operable.

Second, use a battery with the correct amperage that is needed for your vehicle. If you don’t know what’s the needed amperage for your vehicle, you can always consult your owner’s manual and see all the crucial information about the vehicle. If the amperage is incorrect, some seriously bad things can happen both to your vehicle and its battery.

Another thing you should do is to reduce the vibrations by tightening the battery’s hold-down clamps when in use. The vibrations may have negative effects on the battery’s proper functioning and unnoticeably make it useless. Also, you should see if you didn’t leave on your vehicle’s lights as it will cause the deep-discharging that is also known as “killing” your battery. This can happen accidentally to anyone, but be sure that you double-checked if you turned everything off before you left your vehicle.

It is also important that you never keep a battery dead for long periods of time as it can completely devastate the inner chemistry composition that allows for proper functioning of the battery. So try to keep your battery fully charged as often as possible and use a trickle charger to accomplish that.

Guide to Buying the Best Trickle Chargers

All of the 30 trickle chargers featured in this review are among the highest-quality products you will be able to find online. The most important thing about these trickle chargers is that they are worth the money you invested in them as they provide you with crucial benefits that will help you keep your battery life longer. If you are new to the trickle chargers, these are the main features you should focus on before buying any sort of this product.

Portability
The portability proves as one of the key features as it allows you to better use the space you have and position the things in a way that suits your needs the best. The trickle charger should have a cable that is long enough so you can move the charger around the place easily. Also, if you want to use the sun-powered trickle chargers, it’s important that you find the charger models which allow you to place the charger on the sunniest spot and connect it to the car battery with ease.

Safety features
Every product that has to do something with electricity must come with a large set of well-engineered safety options that will reduce the risk of bad case scenarios involving electricity to the minimum. Therefore, you should especially pay attention to the way the particular trickle chargers avoid the fatal occurrences that may completely devastate both the vehicle and its battery.

The standard trickle charger structure usually features a minimum of 3 stages charging process that allows for a gradual implementation of the electrical power to the battery, so the overheating and overcharging can be prevented. The float charging feature is among the most important trickle charger traits you should look for as it prevents the battery from being overcharged.

Compatibility
The majority of vehicle batteries are either 6V or 12V batteries, so it’s crucial that you make sure that you chose a trickle charger that can charge each type. Most of the chargers have a dual charging option that allows you to switch between the charging modes according to the voltage that is needed for your vehicle’s battery. If you apply the wrong voltage on your vehicle’s battery, then you risk doing permanent damage to your vehicle and its battery.

Faster vs. Slower Charging
Don’t get easily tricked by the trickle charger ads that will emphasize the fact that their charger can charge your vehicle battery faster than others. The reason why charging a car better slowly is better than charging it quickly has to do something with the science behind the lead acid battery technology. Generally, when you apply a higher charging amperage, you will speed up the chemical reaction needed for trickle charging, but applying excess charge amperage can generate a great deal of heat. This means that your vehicle battery can get damaged by sudden overheating caused by a fast charging mechanism.

Also, overheating may lead to battery explosion which is the most dangerous scenario you can get yourself into. Have in mind that the main quality of trickle chargers is the capability of detecting the charge level automatically by adjusting the amperage which doesn’t imply the fast conclusion of such a process. It’s better to be patient and wait for the battery to charge properly than to hurry and risk some dangerous consequences.

Easy to use
The simple use of the trickle charger is among the crucial traits you should look for before buying a new charger. It would be best to find a trickle charger that is fully automated and needs no user assistance to operate. In this review, you will find the fully automated trickle charger products that feature a smart detection of the battery amperage followed by the automatic adjustment of powering intensity. It is also important that you look for the chargers that automatically enter a float charging mode, because it enables the charger to stop charging the battery once it’s charged fully, thus preventing the battery from overheating.

Another feature that makes the use of the trickle charger more convenient is the user interface which presents you the information about the charging status. It would be best that you find a charger which has a comprehensive user interface because you will be enabled to monitor the charging status easily and decide whether you will unplug the charger or leave it.

The Verdict

This thorough review was intended to provide you with some useful insights into the main features you should focus on before buying a trickle charger. It’s of great importance that you find a product which is safe to use and which also comes with a set of protection features that will ensure both the charger’s and your vehicle’s battery longevity.
Also, the charger should be easy to install and use afterward, so the best case scenario would be if you find a charger that is fully automated, but also well-engineered and programmed. On the market, you may find some eco-friendly battery charging solutions which may provide you with a decent performance, so you can check the ones we included in the review to see if such products can suit your needs.
