# What is Trickle Charger?

By [Elliot Clark](https://energytheory.com/author/elliot_clark/)November 17, 20232 Mins Read

![Trickle Charger](https://energytheory.com/wp-content/uploads/2023/11/Trickle-Charger-1024x683.jpg "What is Trickle Charger?")

The term trickle charger **denotes a battery charger that operates at a low amperage.** Various battery chargers offer different amperages, allowing for either fast or slow charging based on the specific requirement. Some chargers are also engineered for extended, continuous connection to prevent overcharging. Hence, when people discuss trickle chargers, they are generally referring to these types of chargers.

For general purposes, any battery charger, or trickle charger, delivering approximately 1 to 3 amps is sufficient, and there is no real necessity for one with float mode monitoring unless a continuous connection is desired for a specific reason.

Regarding the choice to charge your battery instead of relying solely on driving, two concerns arise. Firstly, the alternator’s amperage output is restricted, potentially leaving the battery insufficiently charged if your usage primarily involves commuting or short errands. Secondly, [alternators](https://blog.nationwide.com/vehicle/what-is-an-alternator/) are not designed to recharge completely depleted batteries.

### **Trickle Chargers Versus Standard Car Battery Chargers**

A trickle charger is primarily utilized for gradual battery charging and to prevent overcharging, although a standard charger can achieve the same result.

Investing in a trickle charger may be prudent if you frequently store batteries for extended periods. Conversely, if your primary battery charging requirements involve swift charging for immediate use, with intermittent battery storage, it is advisable to choose a regular charger and plan to charge the stored battery every 30 to 45 days.

The defining feature of any trickle charger is its capability to provide either a low amperage option or a consistently low charging amperage. While most trickle chargers discharge approximately 1 to 3 amps, this range is not an absolute standard.

### **Who Needs a Trickle Charger?**

Generally, this charger is more of a convenience rather than a necessity. Despite this, it is a reasonably priced and handy tool to possess. If it’s feasible to leave your vehicle with a mechanic for a day to facilitate a thorough battery recharge and charging system inspection, that’s an excellent option.

If being without your car is not feasible, investing in a low-cost trickle charger would be a wise decision. It is crucial to adhere to safe charging practices and prevent battery overcharging, particularly if you opt for an inexpensive manual trickle charger.
