Trickle Charger Buyer’s Guide
In order to more about Trickle Chargers, I am adding this buyer’s guide so that you can have a clear idea about the Trickle charger.
What is a Trickle Charger?
A trickle charger is used to charge the vehicle’s battery at the rate which is equal to its natural discharge rate. It is needed when car or vehicle is parked for a longer period of time as battery keep on getting consumed. It is suggested that a trickle charger is a must-have device for people who store their vehicles in winter time or use them occasionally.
Trickle charger works at a very slow and steady rate that keeps the battery fully charged without causing any overcharge. There are some models of trickle charger that can be linked to batteries for longer period of time without the risk of overcharing or battery explosion.
Types of Trickle Chargers
There are two main type of trickle chargers which are available in the market; one is Dumb and other is Smart. So let’s talk about them.
Dumb is the traditional style of trickle charger that comes with lots of cables plugging into a socket. They are available in a very reasonable prices that are reasonably powerful. It is available for almost all type of battery sizes.
Smart type of trickle chargers are the modern one which is why they are a bit expensive as compared to the dumb. It comes with ability to automatically adjust the power as per the battery requirement. Smart trickle chargers are the safer and faster options available out there.
How to Choose the Best Trickle Charger?
There are few things that you need to consider before buying a trickle charger which I have discussed below.
The first thing that you need to consider is the engine size before selecting on the trickle charger. If you have a big car then it is probable that your car will have a bigger battery thus you need a bigger trickle charger. The same principle goes for any other type of vehicle.
You need to make sure that the trickle charger that you are buying is sufficient for your car.
You may consider a following example for general idea;
A 1-Amp trickle charger is enough for a small battery like a motorcycle, golf cart etc.
A 2-amp 6V and 12V trickle charger is perfect for multiple battery connectors and it can help you charge both small and large battery chargers. It has multiple choices which give you a kind of freedom to switch between both demands.
Another thing to consider is the battery type while purchasing a trickle charger for cars. If you have a lead acid battery then it will work with all kind of battery trickle chargers. And if you have a gel or calcium batteries then it works with specific type of battery charger.
If you have deep-cycle battery then you should for a charger with deep-cycle program. If you have a gel or acid battery, then you need a charger that comes with three-stage charging procedure.
If you have a liquid battery then it will work with all type of chargers.
If you are person who store your cars for a whole season then you need to look for a charger with automatic battery-charge monitoring feature which will ensure that your battery is not overcharged and it’s topped off as soon battery level goes down. It will with your battery’s health as well.
This is one of the most important feature to consider and that is having a perfect safety feature that prevent the damage to the battery. Some of the basic safety features include; reverse polarity connection safety, spark-proof, short-circuit protection, overheating and overload protection.
Wall Socket Connector
You need to consider this as well as manufacturers make different type of wall-socket connectors for different countries. So you need to make sure that you purchase a charger with a right kind of wall socket connector.
Trickle Chargers Vs Normal Battery Chargers
There may be some of you who wanted to know about the difference between trickle chargers vs normal battery chargers.
Normally, a trickle charge is used to charge the battery at a rate equal to the natural rate of discharge of a battery thus preventing an overcharge. Although, it can be achieved with an standard charger as well; however, a trickle is important where you store your vehicles for a longer period of time.
Moreover, if you are person who like to charge the battery faster and you don’t store your cars for longer period of time then you should invest in normal battery charger.
While working with batteries and all, you need to follow few safety tips in order to avoid any unfortunate mishap.
- Whenever you are working with batteries then always wear safety goggles which will protect your eyes against corrosive lead-acid in-case battery leaks or any explosion occurs.
- In case you are charging an old battery then you should first fill it with distilled water before connecting the chargers – if the water level is too low.
Q. What is the difference between a trickle charger and a battery charger?
A. A battery charger delivers high-amp electrical current to the batteries thus converting AC power to DC at a very low voltage. Moreover, you can’t leave battery charger stay connected for a longer period of time.Whereas, trickle charger are connected to charge and maintain the battery power at a very low pace. You can leave the trickle charger stay connected for a longer period of time without supervision.
Q. Do it cause a damage to battery if a trickle charger is left connected for a longer period of time?
A. It may vary and depends on the type of charger you are using. There are some trickle chargers that comes with automatic control system that charges the battery accordingly. So you need to look at the trickle charger and see if it comes with this feature.
Q. How long should I connect a trickle charger?
A. Usually, a car battery discharges in 20 hours after being fully charged. You should connect trickle charger 10 to 15 hours after being fully charged. However, if you park your car for week and months then you should connect the trickle charger on. It will keep no charging the battery accordingly.
Q. How to connect a trickle charger safely?
A. Connecting a trickle charger is pretty simple and straight forward. You need to hook up the red and black clamps. You need to look for positive terminal of battery (often red) and connect the red clamp on that terminal. After that connect black clamp to the negative terminal (black) of battery. The add the settings either charging or maintenance mode.
So this was all about Best Trickle chargers for cars and I am sure you must have picked one for yourself. Among all, Battery Tender Junior 12 Volt is the best and carries all the required features that should have in a perfect trickle charger.
