Trickle Charger Vs. Normal Car Battery Charger
When it comes to buying a battery charger for the first time, you need to keep certain things in mind like how fast you should charge your battery or how long you should keep the charger plugged in, etc.
A normal car battery charger is designed to charge your car’s battery as quickly as possible. There are certain safety features built-in to these devices to prevent overcharging and keeping the process as safe as possible.
On the other hand, a trickle car battery charger delivers a very low amount of voltage constantly. This is used to keep the battery charged for a long time but at a much slower pace.
Did you know that you can damage the battery if you charge it too fast? That’s why it is important not to rush the process as it can shorten the lifespan or reduce the performance capacity of your vehicle’s battery.
Normal car battery chargers will deliver voltage constantly to recharge the battery as fast as possible. You don’t want to keep it charged for a long time and also check the battery periodically if it is fully charged or not.
A trickle charger is slower, but it reduces the risk of overcharging the battery. Most car owners think that a maintenance charger and a trickle charger are the same. However, while both might have the same functions, they are an entirely different device.
Frequently Asked Questions
Q: Are there different types of trickle chargers?
Ans: Technically, yes. Depending on their features, there are actually two different types of these devices. One is the standard version, and the other is the smart version, which is also more expensive.
The standard ones are ideal for charging any type of car battery, but you should not keep them plugged in for too long. This is where the smart trickle chargers shine the most. They have safety features built-in so that you can keep them plugged in and forget about them.
Q: Are battery maintainers and trickle chargers the same?
Ans: Battery maintainers are designed to cut off the power from the battery when it is full. Afterward, it constantly monitors the charge level, and when it drops to a certain level, the maintainer starts itself and charges the battery again until it is full.
However, a trickle charger doesn’t cut off its power when a battery gets full. It optimizes the voltage flow to match the battery’s self-discharge voltage. Since a battery is always discharging, it will always match the voltage and keep it full topped.
